After 12 years and 600,000 units built of the previous V8, Jaguar has engineered a completely new motor, with just two parts carried over: the exhaust tappets and the cylinder head bolts.
Designed and developed in-house, the new Jaguar V8 arrives initially in 5.0-litre form in both supercharged (503bhp) and naturally aspirated (380bhp) forms. Despite the hike in size compared with the outgoing 4.2-litre V8, and the leaps in power and torque, the new engine does not use any more fuel.
As well as direct fuel injection and variable camshaft timing, the Jaguar XFR’s V8 is fitted with a new, sixth-generation supercharger. Company engineers say the unit is "much, much" more efficient than previous blowers.
It also helps deliver some 331lb ft of torque for the Jaguar XFR from below 1000rpm, before peaking at 461lb ft between 2000 and 5000rpm. Project engineers say that a key aim with the new Jaguar XFR was to provide better throttle response than in rival cars.
The engine drives an upgraded version of Jaguar’s well-established six-speed ZF auto 'box. As well as being able to handle more torque, the ‘box also ‘locks-up’ in second gear and above once the engine has reached 1000rpm. This helps remove the typical ‘slushy’ feel associated with auto 'boxes.
k I want one... Not as much as I want 60K though...OK I found some more info, this page is good

I really do like the lastest jag's the XF and XK, the new engines look great too, if i won the lottery tomorrow, i think i'd honestly take an XK over a Aston V8 vantage, hopefully once this credit crunch has passed i can pick up an older 4.2 supercharged XK for a price thats more affordable, but i do like the way jag is going now, rather then trying to outsell BMW, Merc, with 3 series rivals etc and instead focusing more on making fewer but more desirable cars, looking forward to seeing the rumoured roadster, and XF coupe

Looks fabulous. Love the new wheels. 
I thought these models were going to get the new 7 speed auto g'box?
I think they've updated the 6 speed box (so it locks into each gear), so that it performs better as is.....does a car with this much torque and bhp really need a 7 speed box?I thought these models were going to get the new 7 speed auto g'box?
Also, am I right in assuming that they've dropped the 4.2 petrol completely now? Doesn't that leave quite a big gap from 3.0 litre to 5.0 litre? Didn't they used to have a 3.5 litre, which could provide a bit of a stop gap in the range? And make it feel a bit more complete?
