Audi readies flagship Sport Quattro concept for Frankfurt

Audi will unveil its new Sport Quattro concept at next month's Frankfurt motor show, previewed in a number of sketches. We first saw the Quattro concept back in 2010 at the Paris motor show and three years later the carmaker has produced another iteration, a 2+2 coupé, that measures in at 4,699mm – 419mm longer than the Quattro concept (4,280mm). From what the sketches show, the Sport Quattro retains the chunky C-pillar of the 2010 Quattro concept, the 1984 Sport Quattro and the original Ur-Quattro models, while the four headlamp units are another nod to the original.

One Lap of the Web: An awesome Indian Harley, a Toyota 2000GT for sale and vintage snowmobiles on display

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.
