Jaguar XF gets an early boost

Jaguar XF S diesel now packs 272bhp
Although it only seems like two minutes since the Jaguar XF was launched, it’s already received its first tweaking. The new XF S model goes straight to the top of the diesel tree thanks to its award-winning twin-turbo engine, which has been been expanded to 3-litres and 272bhp.
With an increase in power of 33 per cent to 272bhp, performance has been usefully boosted – but the most impressive of the numbers produced by the new car is its torque figure, which rises to 420lb/ft from 320lb/ft. That should allow the XF S to trade punches with the BMW 535d, the performance leader of the class.
But there shouldn’t be a financial penalty at the pumps or in your tax return, as overall consumption is 42mpg, and the car’s CO2 emissions fall from 199g/km to 179g/km.
The XF S will trade punches with the BMW 535d, the performance leader of the class…
The 3-litre unit comes in two forms, though – with a 237bhp version being offered. It returns the same fuel consumption and CO2 emissions, but it’s marginally slower, with its 0-60mph rising to 6.7sec.
The XF S can be identified by its new 20-inch wheels and a boot lid spoiler.
2009 also sees the arrival of the XF Portfolio, which receives a similar treatment to the XK and XJs; bespoke interior trim and colours, and exterior tweaks will mark these out.
Models to come include the new 5.0-litre XF R super-saloon (supercharged and packing 503bhp) as well as a new entry-level diesel powered by the 2.2-litre unit found in the X-TYPE.
Considering how good the 2.7 was this should be fantastic, and seriously call into question the existence of the NASP V8. 6.7 seconds to 60 for the lower power version – what does the 272bhp one get??

What I would like to know is when is the equivalent of ‘BlueMotion’ going to appear for these cars. I believe that it is 100% possible to dip the CO2 output down to below 150g/km and possibly even further by re-tuning the engine and paying attention to the frontal aerodynamics as well as modifying the under body, and using low rolling resistance tyres.

No, the V8 is for those that don’t want a tractor engine, no matter how fast.. they are still horrbile. The V8 on LPG is still cheaper to run than the deisel version and a vastly more refined
