Rimac: An E.V. Dark Horse Heads to Frankfurt

“Croatia has no auto industry,” says Mate Rimac, a 23-year-old entrepreneur and automotive designer. “But that is about to change.”
Mr. Rimac has recently founded Rimac Automobili in an industrial park near Zagreb, the Croatian capital, where he has been constructing what he calls “a tremendous supercar.”
Mr. Rimac is taking that vehicle, the Concept One, to the 2011 Frankfurt auto show next week, where it could be regarded as the most unexpected vehicle of the hundreds to be displayed.

“It is an electric supercar,” Mr. Rimac said. “It makes 1,088 horsepower, 3,800 newton-meters of torque (2,803 pound-feet) and is capable of going more than 300 kilometers per hour.” For now, he says that the top speed is being electronically limited.
Claims of generating Veyron-like power are remarkable for a car powered by an internal combustion engine, let alone an electric propulsion system. Asked whether the Concept One had been tested to 300 k.p.h. — or if it had indeed been driven at all — Mr. Rimac would say only that the car’s components were tested in a prototype on closed courses. A teaser graphic posted on the company’s Web site depicted the Concept One only in the design and construction phases.
The Concept One is powered by “four independent electric motor drive units,” Mr. Rimac said, producing a total of 800 kilowatts — the factor by which its horsepower calculation was achieved. He anticipates building 88 examples of the car and pricing them “a bit below the gasoline-powered competition from Pagani, Koenigsegg and Bugatti.” Rimac Automobili has firm preorders from “the Abu Dhabi royal family,” he added.
“The front and rear systems are separate units,” he said. “Each of them includes two high-speed, liquid-cooled permanent magnet electric motors, two liquid-cooled inverter units and two reduction gearboxes, integrated into one small unit.”
Mr. Rimac claimed that the vehicle would have a range of 366 miles on a single charge, beating the 300-mile range projected by Tesla for its Tesla Model S Signature series sedan. The Concept One features a carbon-fiber body atop an aluminum frame; total vehicle weight is said to be 3,630 pounds.
Additional details on the vehicle will be made available when the Concept One is introduced on Sept. 13, the first day of press previews at Frankfurt, Mr. Rimac said.
Mr. Rimac said he competed last month in an 800-kilometer “e-miglia” race in the Italian Alps for electric vehicles; he drove an older-model BMW E30 that he converted to run on some of the same electric propulsion technologies he developed for the Concept One.
“We didn’t know what we were doing, but we had fun,” he said. “The car performed great, even though we couldn’t use our speed advantage. We did enjoy passing all the Teslas, though.”

2011 Audi A2 Electric Car Concept









Late last week Audi released some teaser sketches of its A2 concept car due at the 2011 Frankfurt Auto Show, now less than a week away.

Due to be positioned between the A1 minicar and upcoming Audi A3 Sedan compact car, the new A2 is spiritual successor to the original A2, an aluminum-bodied, ultra-efficient subcompact that went on sale in Europe in 1999.

The early information and sketches didn't reveal many details about the A2 Concept but we now know it also uses aluminum construction, and carbon fiber elements too. This helps keep the weight quite low, at 2,535 pounds. That's more than the original A2 but certainly light by electric car standards. That aluminum body is a svelte 12.47 feet long, 5.54 feet wide and 4.89 feet high, but Audi promises impressive interior space.

The electric drivetrain uses a 114 horsepower, 119 pound-feet of torque electric motor, with power going to the front wheels. Performance is brisk at 9.3 seconds to 60 mph, and top speed is limited to 93 mph.

A lithium-ion battery under the floor gives enough charge for 124 miles of range, and can be charged in as little as 1.5 hours using a custom 400 volt charger. Recharging from a regular wall outlet takes 4 hours.



The A2 concept will showcase Audi's new dynamic lighting technology too, known as matrix beam lighting. It uses microreflectors to direct a high resolution and low-glare light pattern onto the road. LED lighting also runs the length of the body and permeates through into the interior.

High-tech rear lighting adapts its illumination depending on visibility and weather conditions, and a laser light unit at the rear can even project a warning triangle onto the road behind the car.

The interior itself is stark and modern as you'd expect from a concept car. It uses a flat floor to give a feeling of space despite the small body size, four individual seats and a center console attached to the driver's seat.

The Audi A2 Concept will join Audi's other take on an urban electric car at Frankfurt, the sporty Audi Urban Concept.

The 2011 Frankfurt Auto Show begins on Tuesday, September 13. You can keep up to date with all our Frankfurt coverage by clicking here.

Tazzari Zero.mp4



Tazzari Zero Electric


The Tazzari Zero is a compact two-seat vehicle powered by lithium-ion batteries.  This gives the car a range of around 140km or about 87 miles. The car has an electronically capped top speed of around 100 km/h (62mph) with acceleration from zero to 50km/h (31mph) in less than five seconds.

Tazzari Zero from the sideThe Zero is therefore not really for your long distance journeys.  It is an urban-focused electric car for those who want to look good as they cruise about town. Including the 142kg battery pack, the Zero weighs under 550kg!
One thing to note however, unlike other electric vehiclest, the Zero has been built to fit within European quadricycle rules, rather than the full-blown passenger car regulations.  Quadricycles are not required to pass crash tests or meet certain other safety regulations.
