Audi A8 facelift revealed ahead of Frankfurt Motor Show 2013

Audi is pulling weight out of its A8 limousine and sticking in more power in an effort to stem the expected upsurge from Mercedes-Benz’s all-new S-Class, also being unveiled for the first time at the 2013 Frankfurt Motor Show. The all-wheel drive Audi, which is the top-of-the-range Audi limo, may only change a little visually but delivers big upgrades in its driver assistance systems, as well as tightening its fuel consumption by up to 10%.

JCB DieselMax

Following its display at the Goodwood Festival of Speed last month, the JCB DieselMax has recently proved itself the fastest yet diesel-powered car during Speed Week at the Bonneville Salt Flats, Utah. Andy Green, who in 1997 broke the sound barrier on land in Thrust SSC, piloted DieselMax to reach a top speed of 350.09mph, increasing the existing record set in 1973 by over 100mph. Helping the JCB DieselMax achieve this is a drag coefficient of just 0.174 and two 4.4-liter four-cylinder engines, each producing 750PS.

"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.
