According to a recent report, Volkswagen will introduce a production version of the XL1 concept in 2013. It will be an advanced plug-in diesel-electric hybrid.
According to Autoweek.nl, an engineer confirmed the production vehicle will keep the concept's advanced plug-in hybrid system which combined a 47 hp (35 kW / 48 PS) 800cc two-cylinder diesel engine with a 27 hp (20 kW / 27 PS) electric motor. This setup enabled the 795 kg (1,753 lb) concept to accelerate from 0-100 km/h in 11.9 seconds, hit a top speed of 160 km/h (99 mph) and travel up to 35 km (21.7 miles) on electricity alone.
While these figures don't sound terribly impressive, by themselves, the concept had an average fuel consumption of 0.9 l/100 km (261.3 mpg US) and CO2 emissions of 24 g/km.
In related news, the engineer reportedly confirmed the two-cylinder diesel engine will be offered in the Up!.
