In physics, the Greek letter "delta'' indicates a change in value, a term that allows you to utter massively cool NASA-speak such as, "What is the delta in vector?'' Or velocity. Or even viscosity.
What do you get for your hard-earned delta? A bump in horsepower, from 325 to 355; a paltry decrease in 0-to-96 km/h, from 4.8 seconds to 4.6; a slight — and almost entirely theoretical — higher top speed of 295 km/h versus 285 km/h. How deep under the jail would you like them to bury you?
