ELIICA


The Eliica (or the Electric Lithium-Ion Car) is a battery electric vehicle prototype or concept car first shown in 2004 and designed by a team at Keio University in Tokyo, led by Professor Hiroshi Shimizu. The 5.1 m (17 ft) car runs on a lithium-ion battery and can accelerate from 0–100 km/h (62 mph) in four seconds (faster than the Porsche 911 Turboat the time). In 2004, the Eliica reached a speed of 370 km/h (230 mph) on Italy's Nardò High Speed Track. The team's goal is to exceed 400 km/h (250 mph), breaking the record set by today's street-legal gasoline-powered vehicles.




Called the Eliica - short for Electric Lithium-Ion battery Car - this radical 800bhp eight-wheeler from Japan is proof that electric vehicles can be fast and fun to drive, too. Boasting a four-second 0-60mph sprint and seven-second 0-100mph time, the Eliica is faster than a Porsche 911 Turbo.

So what is it like on the road? In this world exclusive, we took the controls to find out. As soon as you climb into the snug cockpit, you realise this car is built for speed. It's more than five metres long, shaped like a bullet and carries its batteries, software and motors in a narrow chassis bed, giving it the lowest centre of gravity of any prototype we've come across.

In tests, the Eliica has recorded a top speed of 370kph (230mph), although its inventor Hiroshi Shimizu claims it could clear 400kph (250mph) in the right conditions. "When you're dealing with technology thought by most to be slow, heavy and lacking range, you must do better than any supercar," he said.

At our drive at Keio University near Tokyo, we punched the 'D' button on the dash, pointed the car down the road and flattened the gas pedal. With a faintly audible whirr of eight 100bhp in-wheel motors, the 0-60mph sprint was smooth, effortless, quiet - and surreal. The mind-boggling acceleration was on a par with that of a 500bhp GT racing car. Yet the lack of a transmission meant there were no jerky cog swaps as we were thrust back in our seat by an incredible 0.8Gs.

With that ultra-low centre of gravity, the car handles surprisingly well, and has virtually no body roll or nose-dive. It turns in sharply with well weighted steering through the front four wheels, and gives adequate feedback. And it does not feel as big or as heavy as its length and 2,400kg kerbweight suggest.

The only downsides, apart from the tiny cockpit, are that it takes 10 hours to recharge, and a production version would cost £170,000. To bring Shimizu's research back to the future, he needs a major firm's financial power behind him and the whole electric car movement.

DESIGN DETAILS

The Eliica weighs 2,400 kg (5,300 lb) and seats the driver and three passengers. The body was tested in a wind tunnel. The front doors open forward and the rear doors open upward like wings. The car's platform contains 4 tracks of 80 batteries, which make up one third of the vehicle's cost. They currently require about 10 hours of recharging at 100 volts from empty to full charge, and can be easily charged off a residential power grid.
The car has eight wheels to improve traction, and they are smaller than normal passenger vehicles, so it can be lower to the ground for better aerodynamics and stability. Each of the wheels has a 60 kW (80 hp) electric motor, giving a 480 kW (640 hp) eight wheel drive which can tackle all kinds of road surfaces. The four front wheels steer. The electric motors mean that the Eliica can deliver a smooth acceleration free from gear shifts of about 0.8 g. Each wheel contains a disc brake and employs a regenerative brake system to recover energy.
There are currently (as of 2005) two versions of the Eliica: a Speed model and an Acceleration model. The Speed model is made to challenge gasoline-based records and has a top speed of 370 km/h (230 mph) with a range of 200 km (120 mi). The Acceleration model is made for the street and has a top speed of 190 km/h (120 mph) with a range of 320 km (200 mi).
The estimated cost of development was in excess of US$320,000. Once the team receives corporate sponsorship, they plan to produce at least 200 units. As of early 2007, the projected price was ¥30,000,000 JPY (aboutUS$255,000).
On December 19, 2005, then-Prime Minister of Japan Junichiro Koizumi tested this vehicle in a 10-minute ride to theJapanese Parliament. In 2006, the car was tested by Shintaro Ishihara, the governor of Tokyo, as well as by Naruhito, Crown Prince of Japan.
