In February 2012, Volkswagen confirmed that it would build a limited series of XL1s starting in 2013.
The production version of the plug-in diesel-electric hybrid was unveiled at the 2013 Geneva Motor Show.

As with the 2011 concept XL1, it is powered by an 800 cm³ two-cylinder diesel engine with 35 kW (47 hp) and a 20 kW (27 hp) electric motor.
The combined power output is 51 kW (68 hp) and torque is 140 N⋅m (100 lb⋅ft).
Power is delivered to the rear wheels through a seven-speed dual-clutch gearbox.
The drag coefficient has increased slightly from 0.186 to 0.189.
The production version delivers an all-electric range of 50 km (31 mi), in addition to a 10-liter fuel tank which allows for over 400 km (250 mi) of real-life driving until the car needs to be refueled.

In February 2013, Volkswagen announced that it expected the XL1 to achieve a fuel economy of 0.9 l/100 km (260 mpg‑US; 310 mpg‑imp) and emissions of 21 g/km of CO
2.
The test cycle allows for a re-charge of the battery every 75 km (47 mi) which results in a high mpg value.

Using diesel alone the car is capable of up to 2.0 l/100 km (120 mpg‑US; 140 mpg‑imp).
One reviewer found that, in real-life traffic, with air conditioning on and without attempts at hypermiling, the car is able to reliably achieve 2.3 l/100 km (100 mpg‑US; 120 mpg‑imp).
