The secret behind the world’s most energy efficient car – New Technology

It is produced in 200 copies, weighs 795 kg and cost a fortune.
Ny Teknik have test driven one-liter car, the world’s most energy efficient car.

Volkswagen XL1 is small and easily. Self should be small and pretty to smoothly tricks down in the car. Ny Teknik test pilot hits his head on the carbon fiber roof.

The spectacular model, called “one-liter car” because fuel consumption is less than one liter of diesel per 100 km. That makes it the world’s most fuel-efficient car, according to Volkswagen.

As early as twelve years ago, the company’s then-CEO Ferdinand Piëch an acclaimed travel from Wolfsburg to Hamburg in the company’s first enlitersbil. It was an extreme prototype that was never intended to be made. But today’s XL1 is ready for the market and are manufactured in 200 copies.

Though it there with enlitersbil is not entirely true. XL1: an cheat with little electric power to meet the low diesel consumption. The car is a plug-in hybrid, where the electric motor plus lithium ion battery provides a range of 50 km. Then, take a diesel over.

This way you can run 100 km on 0.9 liters of diesel. Carbon dioxide emissions will then be 21 grams per kilometer, provided that the battery is charged with fossil-free electricity.

The low fuel consumption has two explanations: extreme aerodynamics and hard dieting. Little XL1 is not higher than the average six year old, 115 cm. The body is pear shaped and has enclosed rear wheels, but no mirrors.

The car’s total weight is 795 kg, about 600 kg less than a VW Golf. Most of the steel is replaced by reinforced carbon fiber, aluminum and other lightweight materials. Power Steering missing, but narrow tires and low weight makes the steering quite easy though. Though the test ride is noisy – even soundproofing missing

Suddenly you hear a rattling sound behind your car. A hovering helicopter? Nope, it’s the engine that kicks in when I press a little extra on the gas pedal.

What extreme car cost? 1.1 million. But Volkswagen has not developed a car manufactured in 200 copies to make money. Instead, some of the technology from the project come in handy in future energy-efficient vehicles.
