DRIVEN + VIDEO: The BMW i8 Is Nearly Complete And EVO's Harry Metcalfe Takes It On The Track

So the EVO reviewer concludes that this approx $150,000 BMW i8 drives like a hybrid version of a Toyota GT86 or Subaru BRZ. That must have been insulting to BMW because this is what the German car mags think of the Toyota GT86:

The BMW i8 is not an all-electric vehicle even though BMW has been plugging numerous teasers of the i8 in its advertising and publicity since around 2010. The i8 is a gasoline-powered hybrid with an all-electric driving range of only 22 miles. The i8 will not be the fastest or most revolutionary hybrid -- or electric vehicle -- to be on the market in 2014. Much of the sound that impressed the EVO driver is probably artificially generated (like on BMW's M5 and M135) -- it's unlikely the little 1.5-liter twin-turbo gasoline engine makes all that sound. This wasn't an independent test or review since BMW handlers were with the EVO reviewer throughout the video -- the EVO reviewer is not going to criticize the i8 in front of his handlers.

A Porsche 918 Spyder prototype -- a plug-in hybrid -- has already lapped Nurburging in 7:14 min, which is that track's fifth fastest laptime. Porsche claims it can do 0–100 km/h (62 mph) in 2.8 seconds, 0-200 km/h (120 mph) in 7.9 seconds and its top speed is more than 340 kilometres per hour (210 mph). Here is footage of a prototype on the Nurburgring.

All-electric vehicles are not hybrids since there's no gasoline/diesel engine. The all-electric Tesla Model S (Performance Model) has already lapped Laguna Seca raceway. And I believe Motor Trend is having Randy Probst drive the car on the same track.

Audi and Mercedes have already had car mag writers do laps on tracks with prototypes of their all-electric performance vehicles -- before BMW did it with this hybrid i8.

Several all-electric vehicles (NOT hybrids) have already lapped the Nurburgring race trace. For example, the Audi R8 e-tron did it in 8:09 min -- just four seconds slower than the BMW M3 [one year later, the 417,000 euro Mercedes SLS AMG Electric Drive went even faster, and it's going into production]. See video (onboard and offboard) of the R8 etron's lap on the Nurburgring track.

Wow this is an awesome review. The steering looks very neutral and engaging. And that i-3 sounds pretty nice right now, even if the engine sound is artificially generated. FYI, VW/Audi/Porsche have also been using artificially generated engine sounds for a while.

The reviewer compared the handling of the i8 to that of the GT86. How can any carmaker possibly take that as a slight? GT86 reviews (even German ones) have praised the GT86 especially for its brilliant handling. Fun and engaging handling is what most would describe the GT86, which coincidentally is the opposite of the dull and soulless handling found on the RS6 (according to Auto Bild's UK branch, Auto Express).

The i8 is well-known for its carbon fiber chassis, combination of electric and fuel-efficient petrol engine, low Cd aerodynamics, low center of gravity, sporty handling, and relative affordability.

Comparing the i8's performance to the $850,000 Porsche 918 is tantamount to comparing the LF-A to the M3, and that's downright silly. The only thing the i8, the 918, and a Prius share is their "hybrid" moniker.

BTW, you did not just bring up the R8 e-tron in the same mention as the i8 and SLS Electric Drive. This and the AWD SLS is more of an "Audi" than the RWD R8 e-tron, which is basically a diluted, tech demo version of the one-off, original e-tron concept. An Audi without Quattro? I guess it doesn't matter because electric cars don't need a diff, and since Quattro nowadays just means either Haldex or Torsen - pretty generic stuff.

SLS Electric Drive is coming out? Well, thanks to Audi's ex-chief Duerheimer, Audi has no pure electric car coming anytime soon. That's going to be good for everyone but Audi.

Lol, so you're satisfied with your $150,000 BMW i8 having the "brilliant handling" of the Toyota GT86. That must be why Autozeitung assessed the Peugeot RCZ 200 THP to have more agile handling than the Toyota GT86 (both cars about the same price). Or why Sport Auto's Horst von Saurma -- the highly-respected supercar tester and Nurburgring expert -- supertested the Toyota GT86 on two race tracks (Nurburgring and Hockenheim) and gave it only 44 points out of 100. He was enthusiastic that Toyota/Subaru were brave enough to develop a lower-priced sports car that was useful in "educating the young". Now ask yourself, why did von Saurma give the R8 V10 Plus 87 points out of 100 -- what performance car attributes does it have that the GT86 doesn't?

GreenMachine: "The steering looks very neutral and engaging." Wow, you can see all that from the video.

You shouldn't rely on a kid from Britain's Auto Express to teach you about supercars like the Audi RS6 Avant wagon.
- In Autozeitung's test, the Audi RS6 beat the Mercedes E 63 AMG T-Modell S 4Matic wagon. In Autobild's test of the same two cars, the Mercedes narrowly won only because the RS6 test car didn't have the sport exhaust option, its cargo space was slightly smaller and they didn't know how to use the RS6's launch control.
- Two huge German car mags (Autor Motor und Sport and Autozeitung -- both have much higher circulation is higher than Top Gear) comparison tested the basic Mercedes CLS 63 AMG and the BMW M6 Gran Coupe -- the Mercedes beat the BMW in both tests. Note that the BMW couldn't even beat the basic Mercedes CLS 63 AMG -- that's not the top-of-the-line CLS or E 63 AMG S 4Matic that the German car mags test against the RS6 and RS7.
- Autozeitung tested the Audi RS7 Sportback against the top-of-the-line Mercedes CLS 63 AMG S-Modell 4Matic -- the RS7 won. In other words, the RS7 or RS6 wuld likely beat the BMW M6 Gran Coupe, if ever tested.

The BMW i8 is no big revolution. Audi can easily create a faster hybrid than the i8 by slapping together the S3's 2 liter turbo engine with its existing electric -- and use a light-weight platform from its 'ultra-car' research -- but Audi wants a more revolutionary hybrid than the i8.

It's dumb to assume that Audi has no electric car in development. Audi is still continuing development and trials of multiple electric and hybrid projects. Durheimer's time on the job was too short to have any significant impact on Audi's projects. Besides his replacement is the VW Group's very best manager on technical development. That's why Audi publicized the all-new Audi Sport Quattro hybrid -- based on a different platform than the 2010 Sport Audi -- within six weeks of replacing Durheimer as head of technical development.


Audi could have produced the R8 e-tron if it wanted, though probably higher than its original $150,000 etimated price in 2009.

But Audi wasn't satified with the ran

But Audi wasn't satified with the range of its batteries, especially given the Tesla's range.
My guess is that Audi wants to analyze the actual BMW i8, Tesla, SLS AMG Electric, in order to make an even better all-electric car as well as wait for better battery technology. Audi does not mind being 6 to 12 months late to the party if it makes the better, more advanced and more up-to-date electric car. When Car and Driver drove an R8 e-tron prototype in 2009, it remarked: "the E-Tron looks and acts like a finished product. The flawless execution bears witness to the perfectionism at Audi, which other German carmakers struggle to match."

And even though it decided not to rush the R8 etron into production, Audi is still inviting auto journalists and others to test drive the car, gte feedback and keep making improvments. Unlike other brands, Audi is not willing to rush out an electric car unless it's close to perfect.

Wow that's a lot of babble, with no substance at all.

GT86 has almost 1g in lateral grip, but that doesn't mean other cars can't pull higher numbers. They can. The point is that the GT86 has brilliant handling. Nothing you posted contradicts that fact, or the fact that every major publication has mentioned "fun", "agile", or "brilliant" at least once in their review of the GT86 - Auto Express, Car and Driver, Auto Bild, EVO, Top Gear, etc etc.

I was talking about the handling of RS6. Auto Express said the RS6 was dull and soulless, and yet you brought up a bunch of comparisons like some idiot. None of which actually contradicts Auto Express's remark! In fact, among the publications you gave, one actually supports Auto Express's general view of the RS6, that the MB is better. Truly a good job. Love how you construct arguments with evidences that not only don't support, they contradict.

"Engaging" was his word. I just borrowed it. So now you're also deaf, on top of your other incompetencies.

BTW, I never said Audi isn't coming out with an all electric car at all. But with Audi being completely mum about it, it's pretty clear that Audi is still in infantile pre-production stages.

The truth of the matter is that Audi had to shelve the e-tron projects, due to production concerns. They either can't produce a revolutionary product that's totally different than what's out there or what's coming out. Or they can't make it in profitable numbers.

There are carmakers who haven't figured out the productivity. Audi is obviously one of them. Then there are those who can bring out "revolutionary" products (EVO's i8 review's words). And BMW is one of those companies.

On a separate but related topic - Audi responded to CNN's report that Tesla outsells Audi (and BMW and MB), in a fashion similar to yours: denial and misdirection.

http://www.carscoops.com/2013/05/audi-responds-to-report-about-tesla.html

You probably already know this cuz you follow Audi's page all the time. But then Audi had to quickly take it down. I guess that's the good thing when Audi owns their own website, they can take it down before someone makes them eat their own words. You probably wish you could do that here at Autospies.

"In Autozeitung's test, the Audi RS6 beat the Mercedes E 63 AMG T-Modell S 4Matic wagon."

Interesting the Mercedes out scored the RS6 in most performance categories like handling, slalom, steering, Acceleration, brake feel. Where the Audi scored highest in consumption, multimedia, top speed, and "insurance" lol.

Green Machine: "Wow that's a lot of babble, with no substance at all... some idiot". You're looking in a mirror while typing this, aren't you?

You desperately abuse other posters as "some idiot" while you argue like a used-car salesman trying to sell a car that drives like a $25,000

Toyota GT86 for $150,000. That's the bottom line: the EVO reviewer compared the BMW i8 to the TOYOTA GT86. What should worry everyone interetesting in the BMW i8 is that you are too willing to accept and defend that the i8 will be limited to the drive quality of this Toyota. If you had any pride as a seller of BMW cars you would have stated unequivocally that the i8's drive will be better than an i8.

On the other hand, the Toyota GT 86 is not compared to a Porsche 911 or Audi R8 or even BMW M3. The GT86 is compared against its own class of cheap sporty cars. And yet the GT 86 isn't even the best car in its class of cheap sporty cars, not even in handling -- that's indicated by several authoritative German car mag comparison tests (see below). In comparison tests, the GT 86 is usually the only rear-wheel drive car -- while its rivals tend to all be front-wheel drive cars. So of course some car mags, whose reviewers equate fun to drifting their cars, say the GT86 is fun -- yet the GT86 still loses to other FWD rivals in overall driving aspects.

- Autozeitung assessed the Peugeot RCZ 200 THP as having better handling and dynamics than the Toyota GT86 -- both cars have similar price. Overall, the GT86 came in last, behind the Hyundai Veloster
http://tinyurl.com/mv5swd5

- In Autobild's latest comparison test of eight cheap sporty cars this month, the GT86 came in SIXTH PLACE behind the Renault Megane (1), Ford Focus (2), Volkswagen GTI (3), Mazda 3 MPS (4), Mercedes A 250 (5). After the Toyota (6) came the BMW 125i (7) and Volvo V40 (8). Hmmm, so I guess the i8 is a step up from a BMW 125i, lol.
http://tinyurl.com/ng5aoo2

- Sport Auto's supertest gave the GT86 only 44 points out of 100, and concluded that as a cheap sporty car te GT86 was useful in "educating the young". It's obvious that Horst von Saurma did not consider this Toyota a car for serious or experienced enthusiasts.

Of course Audi will be mum about its future etron projects until each information-release date. It's moronic to claim "it's pretty clear that Audi is still in infantile pre-production stages", especially after I informed you of five things on this blog and earlier blogs:
- in 2009, almost five years ago, Car and Driver drove an R8 e-tron prototype: "the (R8) E-Tron looks and acts like a finished product. The flawless execution bears witness to the perfectionism at Audi, which other German carmakers struggle to match."
- in the past few months, after Audi announced it had postponed production on the R8 etron, it still invited dozens of auto journalists to test that R8 etron as well as other etron projects, thus continually gathering feedback to

- within weeks of Audi postponing the R8 etron, it announced a massive hybrid car in the Audi Sport Quattro.
- Audi has already started advertising the A3 Sportback etron on its website -- it's an etron car that is just awaiting European regulatory clearance to start selling the car. In any case, Audi has already been selling other hybrid models.
http://www.audi.de/de/brand/de/neuwagen/e-tron/a3-sportback-e-tron.html
- Audi can easily create a car to beat the i8 if it wanted. Audi has the advantage of in-house knowledge and competence: Porsche's 918 gasoline-electric hybrid car, Porsche Panamera S E-Hybrid as well as Audi's Le Man-winning R18 diesel-electric hybrid vehicle.

You're babbling BS. Audi did not shelve the e-tron projects, due to production or productivity concerns. Audi simply wasn't satisfied with the range of the existing battery technology (while Mercedes was willing to move into production with a similar range) and, unlike other car companies, Audi is unwilling to use its customers as guinea pigs for beta tests of its first generation all-electric cars. By taking a step back and coming out with an even better product with improved technology, Audi will leap over its rivals like it did with the A8 over the Mercedes CLS and BMW Gran Coupe. When Audi comes out with its all-electric cars, the i8 will possibly become obsolete.

The BMW i8 is definitely not as revolutionary compared to the Tesla Model S or other all-electric performance vehicles. It's simply a gasoline-electric hybrid car that, at best, is an improvement on existing hybrid cars that several automakers already have. At worst it's just an over-hyped hybrid using similar technology that already exists in other hybrids. The EVO reviewer is simply parroting BMW's marketing hype -- he already jumped to the conclusion that i8 is a "revolutionary performance hybrid" in January even though he wasn't allowed to drive the prototype on a frozen lake, lol. And he still has not tested the car, other than just had a short drive with a BMW handler. The reviewer said nothing that justifies calling the i8 "revolutionary".

The i8 is simply a smaller version of a similar hybrid car such as the 'revolutionary' $99,000 Porsche Panamera S E-Hybrid (plug-in with an Audi engine) that's already being sold in Europe: "The Audi-sourced engine alone is good for 333 horsepower and 325 pound-feet of torque, and paired to the battery and electric motors the S E-Hybrid produces a combined 416 hp and 435 lb-ft. Weighing about 250 pounds more than the old S Hybrid, the 2014 S E-Hybrid is the heaviest of the updated Panamera lineup at a staggering 4,619 pounds, yet it still delivers impressive acceleration with the ability to go from 0-60 mph in just 5.2 seconds... In regular driving, the Panamera S E-Hybrid operates in E-Power mode, which does its best to keep the car under full electric power. On the 32-mile 'range and fuel economy challenge' portion of our driving route, we drove 24 miles on

On the 32-mile 'range and fuel economy challenge' portion of our driving route, we drove 24 miles on electricity only and averaged about 1.4 liters of fuel consumed per 100 km (about 168 mpg) in E-Power mode."

You love to throw red herrings on irrelvant
stories that are not related to the topic at hand in order to distract people from the real story -- the 'revolutionary' BMW i8 being compared to the Toyota GT86. STICK TO THE TOPIC. I'm not going to waste everybody's time replying to your irrelevant issues. The comments of an unknown reviewer on a small insignificant car mag like AutoExpress about the RS6 Avant WAGON have NOTHING to do with the BMW i8. Only a stupid person would be obsessed with the steering of the RS6. No wonder an authority like Matt Davis (Co-Chairman of the World Car Awards) said that the whole discourse on Audi's electric power steering "bores us to death at this point... the steering - for an electric setup – is at least smooth, well weighted and predictable – especially as we had the most aggressive optional Dynamic Steering aboard." It's these aspects of the Audi RS6's steering that are important to effectively control the RS6. Thus the RS6 already has the steering it needs -- on a trip through the Alps from Germany to France, Top Gear reported that the $300,000 Mercedes SLS AMG Black Series coupe "had to work hard every step of the journey to keep pace with the RS6."

MercedesSL: The RS6 really should have been compared against the E 63 AMG T-Modell 4Matic wagon (i.e., NOT the 'AMG S' 4Matic wagon which should be compared against the RS6 PLUS that will be coming out next year). After all, the BMW M6 Grand Coupe was comparison tested against the standard AMG cars, not the 'AMG S'. Yet the RS6 wagon (3,129 points) still beat the top-of-the-line Mercedes E 63 AMG T-Modell 'S' 4Matic wagon (3,089 points) -- the RS6 Plus surely will win by an even greater margin.

As everyone can see from the test results and conclusion, Audi won more of the 44 measures than Mercedes did (i.e., not just the few things that MercedesSL pretends to mention). The gap between the Audi and Mercedes were virtually tied on the measures MercedesSL brought up: handling (2 points out of 150 points), slalom (1 point out of 100 points), steering (3 points out of 100 points), acceleration (2 points out of 150 points), brake pressure (3 points out of 25). On driving dynamics, only a miniscule 9 points out of 1,000 separated the Audi and Mercedes.

The Audi RS6 is so good in the real world that even the $300,000 SLS Black Series coupe -- the very best and fastest sports car in the Mercedes product line -- had a hard time keeping up with the RS6 wagon on real-world roads, highways and canyons. Top Gear: "Never forget that this (Mercedes SLS Black) is a very different car from the 'ordinary' SLS.... But you know what? The SLS had to work hard every step of the journey to keep pace with the RS6. The Audi, twin-turbocharged and impossibly muscular, blitzes gaps in traffic and does so with minimal effort. In the SLS, you have to be more alert: you can't just slam on the pedal and spear the horizon -- you need to think about gears and traction and camber and surface and DRIVING the thing. It's immersive and demanding in a way that the RS6 just isn't. In the Audi, once you've mastered mirror, signal, manoeuvre, you don't need to know much more. The car takes care of everything, support you in a quattro cradle, distanced from the actual goings -- on layers of insulation and beefy servos.... The Audi makes speed feel safe; the Mercedes reslishes the danger. We saw 175 mph in both. In the Audi, it was a nonchalant act, done while I was discussing picture requirements with photographer Don Romney... in the SLS, I don't remember breathing.... No one fears the Audi. People get in it and go fast straight away. I bet plenty of people are going faster round the CHarade in the RS6 than anything else. I also bet some of them have outbraked themselves once or twice in the process, faintly shocked at just how effective the twin-turbo 4.0-litre V8 is at heaping speed on."

I never "pretended" the Audi won only a "few" categories....Its just he Mercedes WON MORE of the PERFORMANCE relevant categories, and since these are performance cars...ya know that kind of dictates which is faster and more enjoyable to drive.

Audi & Mercedes cars are prototypes which means they are not in production. And the Range of this car will be about 94 mpg with the gas & electric motors. Find me another car that gets 94 mpg as a sports car.

Porsche 918 spyder is $850,000 + and is powered by a 4.6l V8 / with a small electric motor. Fuel economy is lucky to get around 30 mpg. Maybe 35 mpg to 40 mpg in a leisurely drive.

Audi R8 E-tron is just a prototype and is not going into production at all. So what is the reference to that car ? The range before having to recharge again is 133 miles.

Porsche's claimed fuel consumption is 78 mpg (us). To sum it up: maximum Porsche-quality sports driving fun with minimal fuel consumption.

As far as I know, the Mercedes SLS AMG All Electric Drive is going into production.

Just because Audi decided not to rush the R8 e-tron into production doesn't mean it will never go into production. Even after announcing it's not selling the production-ready car at the moment, Audi is still getting auto journalists to test the car and give their feedback -- in order to improve the car as well as find a better battery solution.

Psst. Do you ever compare like cars or just throw out babble to hear yourself type?

Porsche 918 in all the tests were done on the European cycle and didn't take affect into the electric motor too in which the magazines that have actually tested think that real US fuel economy is going to come in around the 35 to 40 mpg in leisure driving mode, which is pretty awesome. Also the Porsche is $900,000. For that kind of money it had better be the best around without compromise.

The BMW is only going to be slightly over $100,000 and yet you will get around 90 mpg, have state of the art Carbon Fiber frame development, with a 9 gallon tank with a range of up to 800 miles, perform at 0 to 60 is less than 4.6 seconds. That is a crazy combination and is why the reviews are impressive to say the least. Almost shocking to get so much for such low cost.

BMW hit a homerun on this one

Psssssst. Do you always weasel this disingenuously?

BMW4me4ever
: "the Range of this car (BMW i8) will be about 94 mpg with the gas & electric motors. Find me another car that gets 94 mpg as a sports car....

: "Porsche 918 in all the tests were done on the European cycle and didn't take affect into the electric motor too in which the magazines that have actually tested think that real US fuel economy is going to come in around the 35 to 40 mpg in leisure driving mode."

First, you had the audacity to correct my data on Porsche fuel consumption... while you yourself had originally cited i8 fuel consumption claims based on the European test cycle. Why didn't you apply your own standards to yourself?

Car and Driver's Csaba Csere (former chief editor and technical editor) after driving the i8: "BMW claims this plug-in hybrid will be able to drive as far as 22 miles on electric power alone and achieve about 95 mpg—at least on the European test cycle, which provides an advantage to the electric side of the ledger (as does the EPA test). Our admittedly spitballed estimates -- there really isn’t a commensurate plug-in for which we have data -- for real-world combined-system driving are 40 mpg city and 45 mpg highway." MotorTrend: "In comfort mode, BMW is claiming 95 mpg. This is on the European test-cycle and includes the mileage gained from the plug-in hybrid system
http://www.caranddriver.com/reviews/2015-bmw-i8-prototype-drive-review

Second, those "real US fuel economy" on the Porsche 918 you are citing are just guesstimates. No car mag has actually "tested" the Porsche 918 -- they've only had first drives of the pre-production car, usually with a Porsche handler in the car.

Your claim that "The BMW is only going to be slightly over $100,000" is misleading. Thid, Car and Driver estimates the i8 base price at $125,000. Others have had higher figures. [Car and Driver: "Pricing won’t be announced any earlier than the debut of the production version at this fall’s Frankfurt auto show, but don’t expect a number less than $125,000—and that’s for the base car"]

Bottom line, as if anyone who can afford to buy $125,000 / $150,000 cars really cares about fuel efficiency. What they will care more about is why their $125,000 / $150,000 i8 car drives only as well as a $25,000 Toyota GT86.

Car and Driver's Csaba Csere (former chief editor and technical editor) on the i8: "So, from a pure performance-per-dollar perspective, the i8 won’t be able to touch a C7 Corvette Stingray or even a Porsche 911... Whether it lives up to BMW’s bold claims is something we’ll wait to judge until we drive a production i8."
