Diesel cars are increasingly grabbing better auto market shares, owing to the fact that diesel has gotten approximately 30% better mileage than conventional gasoline. Gladly, diesel engines have very impressive torque, due to their marvelous compression ratios and combustion processes. This is the main reason why several trucks that require low-end pulling power wisely use the diesel technology.
Audi unveiled the extremely powerful Q7 V12 TDI concept SUV with a diesel engine at the Detroit Motor Show 2007 to demonstrate its “Vorsprung durch Technik” once again to the auto admirers and consumers. The six-liter SUV supplies 500 bhp of power, and a 738 lb-ft of maximum torque. Audi’s power plant in the US has become the crowning glory of various engines yielding extraordinary efficiency, power and dynamism. The vehicle utilizes an unparalleled twin-turbo diesel 6.0-liter V-12 engine that results to the outstanding torque and horsepower. This cleanly beats the gasoline V-6 and V-8 Q7s designed by the same auto maker, Audi.
The Q7 V12 TDI concept differs in a few ways from its siblings and it’s certainly my pick any day, if it’s lined up with other Q7 models. The most outstanding feature is the monotonous paint strategy, which winds around the side sills and lower bumpers. On the contrary, the lower sections of the standard Q7 are painted with gray color. On the front side of the SUV is located a single-piece grille with two side portals – presumably for tidying up some minor issues of the standard production model of the Q7 that sports a face with unwelcome openings.
Looking at the interior of the concept SUV, you will notice that the standard Q7 seats with smaller side bolsters and separate head restraints have been replaced with one-piece sport seats. Apart from that, there are other minor modifications. Just as other Q7 models, the Audi Q7 V12 TDI concept incorporates accessories like leather upholstery, power front seats and dual-zone automatic climate control system.
Considering the concept vehicle technologically, the 6.0-liter turbo diesel V12 engine has everything except wings to fly. The changeable inlet vanes of the twin turbochargers enable diverse degrees of turbo boost for each exhaust condition. Nitrogen oxide emissions are minimized with a thoroughly-developed interaction between the high- pressure direct fuel injectors and exhaust treatment. This ground-breaking green technology helps the concept SUV to emerge as a vehicle that adheres to the strictest US pollution standards. It’s not surprising why it quickly became the darling of numerous environmental activists.
The V-12 engine with 500 horsepower clearly outperforms the 3.6-liter V-6 (280 hp) and 4.2-liter V-8 (350 hp) engines in the other Q7 models. With just 1,750 rpm yielding an incredible 738 pounds-feet of torque, the Q7 V-12 TDI possesses more low-end grunt than both the V-6 and V-8 models of the Q7 put together.
The power is all routed via a 6-speed auto transmission system with Audi’s trademark Tiptronic manual shifting provision. Subsequently the Quattro all-wheel drive channels the generated power to all the vehicle’s four wheels. As a result, the concept vehicle speeds from 0 to 60 mph in approximately only 5.5 seconds.
