In 2009 and 2010 entries for the 100 MPG X-Prize will run their cars in road tests to determine the winner...
A car that might lose...if entered...would be the 2001 Audi A2 1.2 TDI.
The A2 1.2 TDI is a three-cylinder turbo diesel. The car has an aluminum frame and bodywork and weighs 1881 pounds. The car has four seats, four doors, and a hatchback. The diesel engine makes 60 horsepower and the car gets up to 95 MPG.
Problems ? Well the 0 to 60 mph acceleration is 14 seconds. And there's no air-conditioning or power steering. Oh...the tires are too small.
Other problems ? Well...the fuel mileage in rigorous testing would probably be something like 70 MPG CITY and 90 MPG HIGHWAY or say 78 MPG COMBINED.
Heralds ? Well this was a production vehicle ! And this is a four seat vehicle that gets up to 95 MPG...
