Jaguar XJ 4WD tackles the coldest town on earth (video)

Jaguar XJ 4WD (pictured) tackles the coldest town on earth If you’ve ever driven a Jaguar XJ in any amount of snow, you’ll know it’s pretty useless. You need a handy supply of snow socks and winter tyres too if you’re going to make any length of journey in seriously cold and snowy conditions without stopping to dig yourself out at regular intervals. But Jaguar now has an XJ that can tackle poor and snowy conditions in the AWD XJ (although, sadly, it’s not on sale in the UK) so they’ve headed out on a 2,000 mile round trip in temperatures down to -50 degrees to show that the 4WD XJ just keeps on going.

"Carry-on" engine will power Le Mans racer

NISSAN will this year compete in the famous Le Mans 24-hour race using a revolutionary 1.5-litre, 400bhp engine that’s small enough to qualify as carry-on luggage. The astonishing new technology produces more power per kilogram of engine weight than the 2014 Formula 1 engines, and what’s more it’s set to lead to road car technology. And while the engine block is too heavy to take onto a plane as hand luggage, its 50cm height, 40cm length and 20cm width makes it small enough.
