Audi is a company synonymous with diesel performance. Its efforts at the 24 Hours of Le Mans have repeatedly proven what can be accomplished with a healthy oil-burner at your command, but until now, buyers were unable to pick up spots-oriented models with a TDI badge. That's changed with the debut of the SQ5 TDI at the 2012 Paris Motor Show.
Audi is using the 24 Hours of Le Mans as a launching pad for its latest performance machine. Based on the Q5 crossover platform, the (long-rumored) SQ5 boasts 313 horsepower and 479 pound-feet of torque from its twin-turbocharged 3.0-liter diesel engine to move its not insignificant mass to 60 miles per hour in just five seconds.
