The diesel-hybrid coupe - an un-named development of the decade-old 1L (for 1.0 litres/100km) concept - is capable of less than 1 litres/100km (260mpg) yet can top 160km/h.

The refined version of the one-cylinder diesel-hybrid XL1 now has a two-cylinder diesel mated to an electric motor and has batteries that are charged both while driving and via a plug-in cord. Volkswagen last year showed the third version of the XL1 at the Qatar motor show. It was later caught testing the coupe in cold weather and this month was spotted in Spain for its warm-weather tests.

It is a further development of the 2011 XL1 concept that is a two-seater, and has its origins in the tandem-seat, single-cylinder 1L of 2002 that weighed just 290kg and claimed an astonishing 0.99 L/100km. Volkswagen updated the concept in 2009 as the L1 which retained the tandem seating but added a two-cylinder engine, effectively a Golf 1.6-litre turbo-diesel cut in half then mated to a 10.4kW electric motor.

It had a top speed of 160km/h, accelerated to 100km/h in 14.3 seconds and had emissions of 39g/km CO2. The latest XL1 is different again, now a plug-in hybrid that achieves 0.9 L/100km (260mpg) and CO2 emissions of 24g/km. The 800cc, two-cylinder turbo-diesel engine is rated at 35kW/121Nm and the electric motor
at 20kW/100Nm.

The two powerplants work together or separately and the XL1 can travel up to 35km on electric power alone. Its length and width are similar to the Polo - 3970mm long and 1682mm wide - but it is only 1184mm high. Volkswagen says the 2011 model has a governed top speed of 158km/h and accelerates to 100km/h in 11.9 seconds. In February, Volkswagen said it intended to build a limited series of XL1s starting in 2013.

GoAutoMedia Cars have been the corner stone to Neil’s passion, beginning at pre-school age, through school but then pushed sideways while he studied accounting. It was rekindled when he started contributing to magazines including Bushdriver and then when he started a motoring section in Perth’s The Western Mail. He was then appointed as a finance writer for the evening Daily News, supplemented by writing its motoring column. He moved to The Sunday Times as finance editor and after a nine-year term, finally drove back into motoring when in 1998 he was asked to rebrand and restyle the newspaper’s motoring section, expanding it over 12 years from a two-page section to a 36-page lift-out. In 2010 he was selected to join News Ltd’s national motoring group Carsguide and covered national and international events, launches, news conferences and Car of the Year awards until November 2014 when he moved into freelancing, working for GoAuto, The West Australian, Western 4WDriver magazine, Bauer Media and as an online content writer for one of Australia’s biggest car groups. He has involved himself in all aspects including motorsport where he has competed in everything from motocross to motorkhanas and rallies including Targa West and the ARC Forest Rally. He loves all facets of the car industry, from design, manufacture, testing, marketing and even business structures and believes cars are one of the few high-volume consumables to combine a very high degree of engineering enlivened with an even higher degree of emotion from its consumers.
