It's strongly rumored the diesel version of the Audi TT could find its way stateside. With that in mind, the boys over at Popular Mechanics packed their bags and boarded a midnight plane to Blighty to try one out. In a cable back to their New York HQ, they report the oil-burning 2008 Audi TT 2.0 TDI is smooth, refined and makes overtaking easy as a wiggle of your big toe. Exclusively available in the UK with a 6-speed manual, they calculated their average fuel economy during a mix of city and highway driving to be 39.1 MPG (US). That's while making 258 lb-ft and reaching a top speed of 140 MPH, mind you. Please, god of cars, bring us this beautiful torque-heavy 2.0-liter four-cylinder engine. Please!
