This supercharged V-6 engine was powerful enough that we didn't miss having a V-8.
Jaguar has been at a competitive disadvantage recently - while its cars may be some of the best-driving, best-looking, and best-priced in their categories, they were all only available with rear-wheel drive with a big V-8. Enter the 3.0 - essentially Jag's 5.0-liter supercharged V-8 with two cylinders lopped off. The new forced-induction V-6 is just as fantastic as the eight. Still intact from the powertrain's downsizing is the deep well of power at any speed--even if, unlike the V-8, the V-6 doesn't feel like it has the power of a freight train. Neither does it have the V-8's sonorous and addicting exhaust note, but it still sounds sweet, and appropriate for an $84,000 luxury sedan.
