Track Tested: 2009 BMW 750Li vs. 2009 Mercedes-Benz S550

These are the big guns from BMW and Mercedes-Benz. Well, not the biggest guns, but with prices near or above the $100,000 range, they're big enough. The BMW 750Li is all-new for 2009 and looking better than ever. Its 400-horsepower twin-turbo V8 makes it the closest thing to a "Motorsport" 7 Series we have ever seen. The Mercedes-Benz S550 is getting a face-lift next year, but the current model has held up well. And with a 382-horsepower V8 of its own, it doesn't give up much to the new BMW

I saw my first new 7 at the dealership this past Sunday, a 750. I remember back to 2002 when the new Bangle 7 came it - to me the new design (in 2002) was very exciting and revolutionary/cutting edge. Sad to say, the new 7 does not do much for me. The interior looks great but the exterior is very bland/sleepy/ultra conservative. I would rather take the Benz, which in my opinion, has much more presence and character.

MB is heavier than the Bimmer for more than 100 pounds, it have 18 hp less than the bimmer but still it supass it on the track, that was not fair. I like the benz but to get correct numbers both cars should be equiped in the same way, this test is worthless. BMW should be equiped in the same way (sport package, ABC or whichever they use etc.). If you see the test price there is difference of more than 20,000.00$. Engines are Ok cause the natural aspirated V8 is enough for the ttv8 of the Bimmer....If we compare the cars they should have the same dark color or silver. For "me" the benz looks better than the Bimmer and the facelifted 2010 will be superior by far to the "overconservative" bimmer.

Yonder7....it sounds like you're having a hard time accepting the fact that the Mercedes S550, while being heavier and less powerful, is better rounded than the new 7 series. Give credit where it's due. BMW can't win them all.

There was a review a while back where a 335i w/ sport suspension was compared to an IS350 with standard suspension. And it wasn't surprising that the BMW was the better handler; however noone was calling foul on BMW. Seems to me that only BMW nuts get all bothered when their cars are not the clear winners in a comparison.

Just to clarify, BMW 5.1 sec 0-60, MB 5.7. Despite an "artificially" higher cornering number than the BMW, the MB had identical slalom time. There's no question the BMW would have even more impressive numbers comparably equipped.

Agreed on the overconservative BMW design. Its almost as if BMW is following Lexus' design philosophy of being bland in order to appeal to more (mass) markets.

I disagree. It doesn't get more radical than the grille on the new 7. They "conservati-zed" the rest of the body purely out of criticism from the last one. Despite that, I think BMW created a much more handsome vehicle this time around. All this in mind, I still would take the S-Class as well.

well PUT — Anthony......granted it has a conservative look to it but you cant go overboard with a car like this. the reason why the S550 looks good for 1000th time is because they carbon copied the maybach 57 with VERY little changes. ok they took an exotic design and put on their premium cars of course people will flock to it because they want that maybach look. Do you see BMW taking the Rolls Royce PHANTOM design and making it into the new 78 series NOOOOOOOOOOOOOOOOO because they wanted to stay true and orignal to their designs.....I feel that BMW went back to the 90's on this design the interior the exterior remind me of an updated 94-2001 BMW 7 series. You haters can say what you want but BMW did an outstanding job with this car.

Because they actually do tests right, with scrutiny due, using precise measuring devices and Society of Automotive Engineers correction factors.

Results:

BMW 750Li (Mercedes-Benz S550)

Handling:
Slalom (mph): 63.4 (63.4)
Skid Pad Lateral G: 0.84 (0.87)
Handling Rating: Very Good (Very Good)

Braking:

60 - 0 (ft): 111 (108)
Braking Rating: Excellent (Excellent)

Remember these readings, children. Clearly BMW "legendary" handling and driving dynamics are completely overrated. The big Mercedes, typically considered floaty and pensioners - oriented handles just as well and comes with even higher limit of grip and braking performance.


| BMW handling comment: [...] Amazingly "buttery" steering feel [...]

As you can see, even the "magic" steering feel has left BMW.

Remember the BMW did not come with ABC and what about the tyres, the BMW came on all season tyres the Benz did not, there will be a big difference if they where equiped the same way.

Fair enough, we'll remember if you promise to remember to read before you speak. The Benz had the AMG Sport package. It was $22k more than the BMW. The BMW was essentially totally base. And yet in base form, the BMW held dead even with the most sport S550 they make. With no Active Roll Stabilization, no four wheel steering, etc., it was dead even with the top of the line AMG Sport S550. I wonder how it would've done with those items?

MrBratwurst: I am and MB fan but you have to read the whole article before to talk....please do it and then place your coments again...and again MB price tag is more than 20.000.00$ bucks over the bimmer....ABC and AMG Sport package may be?....please read..

Obviously I read it carefully. Yes, the Benz is more expensive but you get better handling and more equipment for the money.

I just wanted to point out that BMW driving dynamics are overrated.

"Yes, the Benz is more expensive but you get better handling and more equipment for the money."

No, you get what you pay for. If you read the comments section of the Edmunds article, they say they were unable to procure a loaded 750Li. The difference in price was a whopping $22k between the two cars. Considering what they testes was the most basic, non-sporty 750Li against the highest level, most sporty S550, that says more to me about how good the 7-Series is than how good the Benz is. Imagine how good the 7 would have been WITH the ARS and four wheel steering? It would have beaten the Benz in every performance category.

Do I think performance is going to be what drives sales for luxo-cruisers like these? No. But if that's what we're using as a yardstick here, the 7-Series wins. It just does, period.

Everyone knows that the LS460 is simply a rebadged Camry. It is cheap, unreliable, ugly, slow, tacky, and has no snob appeal, no heritage and is only a immitation of the real thing. Why would anyone in their right mind compare it to anything German? Germans make the best cars, don't argue with me, even if I'm wrong.

Wonderful.

As if the original David999 with his constant Toyota/Lexus spin was bad enough, we have had to listen to faux David969 who has taken the joke (that was barely funny to begin with) way too far, and now we have another David, 959, further inundating the site with useless comments.

Bmw8ter, Do not get me wrong, I am a MB fan but not biased. I like fair numbers, so in order to get those we need the same conditions...Now even in the case that the numbers claim the Bimmer as winer...In luxury the benz still the king. BMW is the king in M3 category on the tracks, C63 have better numbers in almost every line but it is heavier and it can not win to the newton laws (inertia). The "new" bimmer looks already outdated...

Another comparison with out comparing like optioned cars. The BMW 7-series, is a LWB version with the optional 19" wheels. Missing is the Sport Package ( 4 wheel steering & Active Roll stabilization ). Those 2 features alone would make a huge difference in the handling of the BMW.

The Mercedes on the other hand has the Sport Package on it + the Active Body Control. If the Mercedes S550 didn't have that package, then it would be a softer drive. Hence the figures would have been different.

Either way, the BMW is a better overall car than the Mercedes S550. Luckily where I work we offer both the S550 and BMW 750Li
