We're used to seeing plenty of highly modified petrol cars but every now and then a tuned oil-burner crops up. This time it's from the Bavarian-based Abt Sportsline, which has taken the wraps off its new AS6 3.0L TDI. The new car boasts a rare 100hp (75kW) per liter output, with a total 300hp (225kW) churned out by its 3.0L TDI mill. The maximum torque, which arrives at 4000rpm, is a staggering 600Nm.
The increases come from a series of upgrades including new engine management software and more boost from a custom Abt compressor. With the new performance numbers, the AS6 completes the 0-100km/h sprint in 6.9 seconds and a top speed of 249km/h.
Ensuring all that torque reaches the ground, engineers added a set of 20in wheels measuring 9in across. They also upgraded the brakes, added an adjustable suspension set-up and a complete bodykit. The latter consists of a set of side skirts, front spoiler and pumped fenders.
