The XL1, which looks like it could have driven off the set of a sci-fi movie, is the most fuel-efficient production car in the world, with a European combined fuel consumption rating of 261 mpg and CO2 emissions of 21 g/km. Thanks to its plug-in hybrid system, this two-seater can also cover up to 31 miles as a zero-emissions electric vehicle.
To achieve this incredible fuel economy, Volkswagen engineers married an incredibly efficient, diesel-electric plug-in hybrid (PHEV) powertrain with a lightweight carbonfiber structure and the best aerodynamics of any production car in the world. The XL1 weighs just 1753 pounds, has a coefficient of drag of just 0.189, and uses a 48-horsepower two-cylinder turbocharged and direct-injection TDI® Clean Diesel engine that is mated to a 27-horsepower electric motor, a seven-speed DSG® dual-clutch automatic transmission, and a 5.5 kWh lithium-ion battery. Thanks to this formula, this super-efficient Volkswagen can cruise at a constant 62 mph while using just 8.3 horsepower. In all-electric mode, the XL1 requires less than 0.1 kWh to cover more than 0.6 miles (one kilometer).
The 261 mpg fuel consumption figure is a record for a production car, showing that Volkswagen is in the automotive industry’s technical vanguard. The XL1 also has a top speed of 99 mph and can accelerate from 0 to 62 mph in 12.7 seconds.
Conceptually, the XL1 represents the third evolutionary stage of Volkswagen’s 1-liter car strategy. At the start of this current millennium, Prof. Dr. Ferdinand Piëch—currently Chairman of the Supervisory Board of Volkswagen AG—formulated the visionary goal of producing a practical car that had a combined fuel consumption of one liter per 100 km (235 mpg). In the two-seat XL1, this vision has become reality.
Despite the tremendous efficiency of the XL1, the engineers and designers successfully came up with a body design that delivers more everyday utility than the two previous prototypes. In the L1, the 1-liter car that was shown in 2002 and 2009, the driver and passenger sat behind each other for optimal aerodynamics; in the XL1, the two occupants sit slightly offset, side by side, almost like a conventional vehicle.
The XL1 is 153.1 inches long, 65.6 inches wide, and just 45.4 inches tall. By comparison, a Volkswagen Polo is slightly longer (156.3 in) and wider (66.2 in), but is significantly taller (57.6 in). Even a purebred sports car like today’s Porsche Boxster is 5.1 inches taller. Just 250 XL1s will be produced at the Volkswagen factory in Osnabrück, Germany, priced at approximately $145,000.

The Volkswagen XL1, the most fuel-efficient and aerodynamic production car in the world, made its U.S. debut at the 23rd Annual Society of Environmental Journalists (SEJ) Conference at the Chattanooga Convention Center today. The XL1 offers an estimated European combined fuel consumption rating of 261 mpg (more than 200 mpg estimated in the U.S. cycle) and can cover up to 32 miles as a zero-emissions vehicle in all-electric mode.
“The XL1 offers a glimpse into Volkswagen’s present and future eco-mobility capabilities, and highlights the ultimate successes of ‘Thinking Blue’,” said Oliver Schmidt, General Manager of the Engineering and Environmental Office (EEO), Volkswagen Group of America, Inc. “Volkswagen is proud to debut this ultra-fuel-efficient vehicle before the Society of Environmental Journalists, a group that shares in our commitment to environmental stewardship.”
In addition to the XL1 display, Volkswagen’s participation in the SEJ Conference included a tour of its LEED® Platinum-certified Chattanooga manufacturing plant and solar park; test-drives in its line of eco-friendly cars, such as the e-Golf, Passat TDI Clean Diesel and Jetta Hybrid; and a bird-watching expedition on Volkswagen Chattanooga’s sanctuary grounds.
XL1 Features
The XL1 is an automotive standout that follows pure sports-car design principles: light weight (1753 pounds), exceptional aerodynamics (Cd 0.19), and a low center of gravity. This super-efficient Volkswagen has the ability to cruise down the road at a constant 62 mph while using just 8.4 PS (6.2kW) horsepower. In all-electric mode, the XL1 requires less than 0.1 kWh to cover more than a kilometer.
The XL1 emits just 21 g/km of CO2, thanks to its high-tech lightweight design, aerodynamic efficiency, and a plug-in hybrid system consisting of a 48 PS (35kW) two-cylinder TDI® engine, a 27-hp electric motor, a seven-speed DSG® dual-clutch automatic transmission, and a lithium-ion battery.
The estimated European driving cycle of 261 mpg fuel consumption figure is a record that has not been achieved by any other vehicle to date, showing that Volkswagen is redefining what is technically feasible in the automotive industry. The XL1 also has a top speed of 99 mph and can accelerate from 0 to 62 mph in 12.7 seconds.
Conceptually, the XL1 represents the third evolutionary stage of Volkswagen’s 1-liter car strategy. When the new millennium was ushered in, Prof. Dr. Ferdinand Piëch, now Chairman of the Supervisory Board of Volkswagen AG, formulated the visionary goal of putting into production a practical car that had combined fuel consumption of one liter per 100 km (235 mpg). In the two-seat XL1, this vision has become reality.
Despite the tremendous efficiency of the XL1, the engineers and designers successfully came up with a body design which delivers more everyday utility than the two previous prototypes. In the L1, the 1-liter car that was shown in 2002 and 2009, the driver and passenger sat in a tandem arrangement for optimal aerodynamics; in the XL1, the two occupants sit slightly offset, side by side, almost like a conventional vehicle.
The XL1 is 153.1 inches long, 65.6 inches wide, and just 45.4 inches tall. By comparison, a Volkswagen Polo is slightly longer (156.3 in) and wider (66.2 in), but is significantly taller (57.6 in). Even a purebred sports car like today’s Porsche Boxster is 5.1 inches taller. The XL1 will look spectacular going down the highway—a car of the future, built for today.
Volkswagen’s futuristic XL1, the world’s most fuel-efficient production hybrid car, took to the streets of the capital yesterday.
The two-seat diesel-electric hybrid, which achieves a fuel consumption figure of 313 mpg while emitting just 21 g/km of carbon dioxide, turned heads as it passed through the streets of the city, with its white carbon fibre body shell standing out in contrast to black cabs and red double-decker buses.
While one XL1 made its way to the Goodwood Festival of Speed to take pride of place on the Volkswagen stand and make its way up the famous hill climb, another crossed the capital, heading to Buckingham Palace where it will be displayed as part of the Coronation Festival this weekend (for more details see below).
The super-innovative, ultra-frugal XL1 model looks like a vision of the future, but it is in fact already in limited production. Its body is made largely of carbon-fibre reinforced polymer, while its drivetrain melds a two-cylinder 800 cc diesel engine with an electric motor. Like any good supercar, it is also low (at 1,282 mm high it is lower than a Porsche Boxster) and features scissor-opening doors (although its 120-litre boot does make it somewhat more practical than supercar enthusiasts may like).
To achieve the target fuel consumption figure the XL1 was aerodynamically optimised, adopting the classic ‘tear drop’ shape and utilising innovations such as removing traditional wing mirrors and replacing them with small cameras called e-Mirrors which transmit exterior images to interior displays.
The XL1 is manufactured (left-hand drive only) at Volkswagen’s Osnabrück factory in Germany (which also produces the Golf Cabriolet and Porsche Boxster). Unlike these cars, the XL1 is ‘handcrafted’ using small series production processes. An initial production run of 250 XL1 vehicles will be made. Pricing and sales channels are yet to be confirmed.
