Formula XL1 can travel up to 22 miles on battery power alone

We don't usually think of the Qatar Motor Show as a place where major automotive product announcements/advances are made, but Volkswagen used the show to unveil the latest in its line of vehicles aimed at extracting the ultimate mileage out of a single gallon of gasoline.

The German company today announced its Formula XL1 concept car that makes use of a two-cylinder turbodiesel engine, hybrid electric motor (with a lithium-ion battery pack), and a seven-speed dual-clutch transmission. The Formula XL1 has enough juice from its lithium-ion pack to travel for 22 miles on battery power alone, and gets a total combined fuel efficiency rating of 260 mpg.

When the subject of gasoline electric hybrids is brought up on DailyTech, there quite often is chatter from our European readers stating that they have been getting similar -- if not better -- mileage from turbodiesel engines for years in similar vehicle types. So it's nice to see that VW is taking the best of both worlds with this new vehicle concept. 

And it's not just the turbodiesel-electric hybrid powertrain that gives the Formula XL1 its impressive fuel economy; the vehicle also makes use of lightweight carbon fiber reinforced polymers for the body panels to further reduce weight. The driver and passenger also sit in a tandem arrangement -- the passenger sits slightly aft of the driver and behind the driver's seat (think McLaren F1) -- which allows the Formula XL1's body to cut through the wind more efficiently, which also improves overall fuel efficieny. 

There is no word if or when such a vehicle will be put into production, but we're sure that there are more than a few hypermilers here in the United States that wouldn't mind getting their hands on one.

Anyone who uses a MPG rating based on driving 40 miles is an idiot.

No this care is based on the challenge of the head engineer at VW, to develop a car that drives 100km on 1L fuel(235 mpg)

The original idea came from the One-Liter Car concept 10y ago
quote:
VW unveiled the slick two-seater concept six years ago at a stockholder’s meeting in Hamburg. To prove it was a real car, Chairman Ferdinand Piech personally drove it from Wolfsburg to Hamburg. At the time, he said the car could see production when the cost of its carbon monocoque dropped from 35,000 Euros (about $55,000) to 5,000 Euros (about $8,000) — something he figured would happen in 2012. With carbon fiber being used in everything from airliners to laptops these days, VW’s apparently decided the cost is competitive enough to build at least a few hundred One-Liters.

As its build following that concept, i presume this one also drives whit out plug-in support the rated 261 MPG.

Wired has a excellent article about this car.

I for one would for sure put this ore cars like it on my short list to replace my GS450h in 2 years time.
