The XL1 is slated to ride on Volkswagen's new modular MQB platform. No official photos of the car have been released, but sources say that it will closely resemble the concept presented in Qatar. If that is the case, the car will have a length of about 153 inches, a width of 65 inches, and a height of 45 inches.
What is certain is that the XL1 will be powered by an all-new 800cc two-cylinder diesel engine. It is rated at 48 horsepower and 88 lb-ft of torque, and will be bolted to a seven-speed DSG transmission.
The oil-burner will work in conjunction with an electric motor that puts out the equivalent of 27 horsepower and 103 lb-ft of torque. Electricity will be stored in lithium-ion batteries, and the XL1 will be able to travel up to 24 miles in all-electric mode.
The plug-in hybrid drivetrain is expected to propel the XL1 from zero to 62 miles per hour in about 11.9 seconds. Its top speed will be electronically limited to 99 miles per hour.
The first XL1s are scheduled to be delivered in 2013. Volkswagen did not mention how many examples it plans on building, where they will be sold, how much each will cost, but more information is expected to be released before the Paris Motor Show opens its doors next fall.
