2010 Jaguar XK Portfoio & XKR
2010 Jaguar XK Portfolio & XKR
Press release: http://www.autoblog.com/2009/01/10/d...tty-has-claws/
Performance and efficiency. These are the two cardinal attributes that all car designers are aiming for these days, and Jaguar is no different. For the last few years, the automaker's latest XK has relied heavily on its riveted and bonded aluminum-intensive architecture to achieve low weight, which is the first necessity for sporting credentials. For 2010, Jaguar is taking that successful formula and adding lots more power via an enlarged version of its AJ V8 engine. Direct injection, variable valve timing and a variable-geometry intake manifold all conspire to increase power to 510 hp while also having the desirable effect of improving fuel efficiency. Of course, an impressive engine is only a small part of the overall desirability of a new car, and Jaguar claims to have given its XK line, available in both a Portfolio model and uplevel R-model for the 2010 model year, a thorough freshening. So, what are they on about? Plenty, it seems. Keep reading.
The all-new AJ-V8 Gen III engines are the most efficient Jaguar has ever produced. They deliver significantly more power and torque than the previous generation of engines: 510bhp and 461lb-ft of torque in the new supercharged XKR and 385bhp and 380lb-ft in the XK Portfolio.
With the introduction of these all-new 5.0-liter direct-injection V8 engines comes a new level of performance for the XK, with improved acceleration from standstill and stunning in-gear acceleration times. All models are electronically limited to a maximum speed of 155mph, but the 0-60mph sprint for naturally aspirated coupe models falls from 5.9 to 5.2 seconds, while for the supercharged XKR Coupe, 0-60mph is reduced from 4.9 to 4.6 seconds.
