CAR interviews Ian Callum (2013) at Frankfurt motor show

With XK, XF, XJ and F-type, design boss Ian Callum has transformed Jaguar from a brand unable to shake off its retro past into something edgier, cooler and altogether more modern. Now his C-X17 concept promises to take things a step further, breaking Jaguar into the crossover SUV market for the first time ever. CAR caught up with Callum ahead of the concept’s official unveil for an in-depth Q&A session.

Porsche 918 Spyder races toward production

OK, let's put the usual arguments to rest first: The Porsche 918 Spyder is going to be even faster than the Carrera GT in a straight line. That's based on Porsche's own computer simulations in anticipation of the production version of the gasoline-electric-powered 918 Spyder, which is due to roll off a dedicated line within a decommissioned paint shop at Porsche's Zuffenhausen, Germany, headquarters next year. The claimed 0-to-62-mph time is 2.8 seconds; 0-to-124 mph is 8.9 seconds, and top speed should be about 202 mph, thanks in part to series of active aerodynamic functions, including a multistage rear wing.

Lexus CT 200h: The emissions

Teh Lexus CT 200h has emissions of just 96g/km We have to go with the flow on this because, although we have no faith in the assertion that man is responsible for climate change, for as long as Governments penalise and promote cars based on the emissions of CO2 from their tailpipe (I know, it’s barking) we have to accept that car makers will respond to that stick and carrot. Which is why we see a raft of car makers churning out ‘Eco’ cars with a 99g/km emissions figure, as sub-100g/km of CO2 emissions is the Holy Grail for maximising tax effiecencies. Of course, Lexus has gone a step further and seem intent on producing only hybrid cars as soon as possible.
