Toyota Yaris Hybrid-R concept (2013) at Frankfurt motor show

Toyota has released fresh information regarding its 414bhp supermini concept ahead of its debut at next month’s Frankfurt motor show. The Yaris Hybrid R drivetrain features Toyota Motorsport’s 1.6-litre racing petrol engine to power the front wheels and twin electric motors generating 60bhp apiece to run those at the back, giving the car all-wheel drive and a combined output of up to 414bhp. The car also makes use of a supercapacitor inspired by Toyota’s TS030 Hybrid Le Mans racer – energy generated under heavy braking is stored and can be quickly deployed to the rear wheels for an extra burst of power.

Nico Rosberg (pictured) takes pole for Mercedes at Monaco 2014 Nico Rosberg has taken pole position for tomorrow’s Monaco Grand Prix, but the way in which he took pole position does leave room for doubt. Rosberg did seem quicker in final qualifying, but he ‘went off’ at the Mirabeau corner as final qualifying was coming to a close and depriving Lewis Hamilton of the chance to grab pole on his last qualifying lap.

Lutz's Cadillac puts on a better show than Lutz

"Hi, I'm Bob Lutz, and this is the Cadillac CTS-V Drive Challenge." General Motors Co.'s marketing chief dons his monogrammed helmet and puts Cadillac's 550-horsepower sedan through some warm-up laps at Monticello Motor Club, a members-only track. In what might have passed as a dismissible moment of Lutz braggadocio, "Maximum" Bob has challenged anyone with a four-door sedan to beat his 2010 CTS-V. Though not a showman by trade, Lutz is bankable for amusing, bald-faced assessments of his employer, his critics and the auto industry at large.
