British media is reporting Volkswagen is currently working on a larger four-seat version of the XL1.

The ultra-frugal XL1 will soon get a four-seat brother that is expected to feature just about the same amazing fuel consumption number of 0.9 liters / 100 km (261 mpg US or 313 mpg UK) with CO2 emissions of 21 g/km. We remind you the Volkswagen XL1 has an all-electric range of 31 miles (50 km) and an overall range of 310 miles (499 km).

While the XL1 tips the scales at 795 kg (1,752 lbs), the four-seater likely to be called "XL2" will be approximately 140 kg heavier due to the added rear doors, extended center cell, two rear bucket seats and a slightly bigger battery.

The rear doors are rumored to be rear hinged while the XL1's 48 PS two-cylinder 800cc diesel engine will likely get a bump in power. The 27 PS electric motor will probably receive the same treatment to compensate the additional weight. Performance figures should be in the same region as those of the XL1 so expect the XL2 to cover the 0-62 mph (0-100 km/h) run in 12.7 seconds before hitting an electronically-limited top speed of 100 mph (162 km/h).

The XL2 could come out next year as it is believed Volkswagen wants the model to go up against the fuel cell Toyota Mirai.It won't be cheap taking into account the XL1 costs a whopping 110,000 EUR in Germany so the XL2 will be even more expensive.
