Volkswagen has officially unveiled the Formula XL1 concept, ahead of its debut at the Qatar Motor Show.

Essentially the latest in a long line of "one-liter" cars, the XL1 is a symphony of technology and efficient engineering. How efficient, you ask? It has an average fuel consumption of 0.9 l/100 km (261.3 mpg US) and CO2 emissions of 24 g/km.

To get these record-shattering numbers, the XL1 is equipped with a 47 hp (35 kW / 48 PS) 800cc two-cylinder TDI engine and a 27 hp (20 kW / 27 PS) electric motor that draws power from a lithium-ion battery. Connected to a seven-speed dual-clutch transmission, the 795 kg (1,753 lb) concept accelerates from 0 to 100 km/h in 11.9 seconds, before hitting an electronically limited top speed of 160 km/h (99 mph). More importantly, the car can be driven in EV mode for a total of 35 kilometers (21.7 miles).

In terms of styling, the XL1 features an aerodynamic design that incorporates LED lights, upward-swinging doors, and carbon fiber reinforced polymer (CFRP) body panels that were formed using VW's advanced Resin Transfer Molding (aRTM) process.  This, combined with a carbon fiber monocoque chassis, ensures the car is strong and lightweight.

Inside, everything looks pretty conventional (aka production ready) as XL1 drops the L1's tandem seating arrangement for a more traditional side-by-side setup. Despite this practical change, the boot only holds 100 liters (3.5 cubic feet) of luggage so don't go on any shopping sprees.

While the XL1 is technically a concept, Volkswagen mentioned "production" enough to ensure that there's no mistaking a one-liter car will be offered in the near future.
