Audi's Roadjet concept is yet another crossover in a show that's full of them. This high-riding hatchback/wagon/SUV is sized between the A4 and A6. A 3.2-liter V-6, amped up to 300 hp and 236 lb-ft of torque, drives all four wheels via a seven-speed DSG transmission. Audi claims a 0-to-60 mph time of 6.3 seconds. Although the Roadjet is a concept, Audi says a similar vehicle "will be available soon in series production." While the exterior looks ready for production today, we'd expect the interior to see some changes. In the show car, there are four individual seats in two rows, plus, in the third row, a centrally located center seat that slides forward and back; alternately, a rear-facing child seat or a center console can be installed in the space. Audi's MMI Multimedia Interface is enlarged to 10 inches and incorporated into the gauge cluster. Rear-seat riders each get their own, smaller MMI screens. In place of sun visors, the windshield's opacity can be controlled electronically. The rear load floor powers up and back to ease loading. The rear-seat console features a built-in espresso maker, for those long stretches between Starbucks.
