200-mph electric racecar to break track records

Paul Drayson unveils his racecar at the 2011 Motorsport Association’s Low Carbon Racing in Birmingham.

The Lola/Drayson B12/69EV racecar is designed to go from 0 to 100 mph in 5.1 s.

The new features active aerodynamic at the front and rear (shown in that were developed by Cars.

The electric racecar’s battery pack sits behind the driver’s cockpit.

Drayson, Managing Partner at Racing Technologies of Kidlington, is looking to make a statement his new Lola /Drayson B12/69EV a 200-plus-mph (322-plus-km/h) electric demonstrator.

“Even though the car market is struggling a bit right it seems certain that cars are going to be an important of the car business, so if motor racing to remain relevant it needs to go he said. “And electric will provide a new opportunity to get the public to appreciate and understand the of electric cars.”

“At the moment, we seen electric racing but it’s the only way to judge the performance of electric cars,” the peer and former Minister of and Innovation continued. “After we don’t judge the ultimate of internal-combustion cars by what a Focus can do.”

“Of course, we’re not doing for charity,” he added. “We see it as a good opportunity.”

Low carbon racing

The electric racecar was introduced at the 2011 Motorsport Industry ’s (MIA) Low Carbon Racing in Birmingham. Drayson, who is president of the hopes that a derivative of the car be entered in the FIA Formula E series for racecars, which begins in

The fact that “it will be as fast as conventional racecars” come as no surprise, he noted, the car exploits “the know-how the U.K. motorsport industry has to something quite extraordinary.” The e-racer showcases innovative including active aerodynamics, charging, electrical regenerative and perhaps structural battery “making it one of the most innovative motorsport projects in the world.”

electric B12 is a prototype whereby we can many of the systems and new ideas we to use on the racetrack,” he said. “To build high-performance electric cars, you need to get running experience on the where the stresses and strains are different than those by a road car.”

Such trials are particularly for learning how to optimize high-power motors for racing, “which is parallel to what we had to do with racecars powered by internal-combustion

Track testing will later this year.

fact that the cars are to be on streets right in the heart of makes it more relevant to and that’s what motorsport has to he emphasized. “The real of electric racing is that it can people’s perceptions about an electric car can do.

“It also spurs which is what motor has always done—accelerate the development of new which then come to road cars a few years Drayson continued.

Despite the new high maximum speed, drive technology is nowhere competitive in terms of range, so the E race format will run 15-minute heats with a battery-recharging period in between. The itself is designed to operate for 20 at maximum power, he said.

believes that Formula E’s open rulebook has the potential to racing: “The rulebook no limit on power and is completely regarding aerodynamics.” Its main are that the vehicle fit into “a box specified dimensions and that weight should not exceed 300

“The car, for example, has charging,” he said. “No power is needed to charge the car, that’s sure to come to cars in the not-too-distant future.”

aerodynamics

The electric racecar began at the start of last in collaboration with Lola International, a leading chassis based in Huntingdon, U.K. with Lola’s participation is Drayson stated, because the brings with it its extensive in high-performance chassis technology and its developments in active aerodynamics.

The new racer is based on today’s LMP1 B12/60 Le Mans chassis. At 1085 kg (2392 with driver, the modified car somewhat more than the 900-kg (1984-lb) LMP1

In wind-tunnel experiments, Lola have developed moveable surfaces on the front wheel flaps, the rear panel, as as the rear wing, he reported. actuators under the driver’s adjust position of the surfaces to downforce or shed drag as The driver can, for example, opt to cut on the straights to place less on the battery by lowering the wing.

the degree of drag reduction “is because we don’t want to balance of car, it is quite he said, noting that the use of aerodynamic surfaces “means it takes a finite amount of for the airflow to reattach and alter the characteristics.” This is a new effect the drivers will have to how to control correctly.

Electric powertrain

The company’s electric drivetrain, which four asynchronous pancake affixed to the rear axle, 850 peak hp (633 kW). The motors were supplied by Motors. a start-up firm was spun out of nearby Oxford .

“The high power-to-weight of the motors pose some challenges, which led us to use dual and air circuits for cooling,” he said.

The 300-kg (661-lb) battery which was manufactured by Mavizen of Cross, U.K. consists of two modules containing lithium-ion cells from A123 of Waltham, MA. The battery units, are embedded in the structure itself to weight efficiency, reportedly 60 kW·h of energy at 700 V (maximum).

The power feeds into inverters provided by Rinehart Systems of Wilsonville, OR. The B12/69EV’s control technology was supplied by of Cambridge, U.K. which the original system for the standard B12/60 chassis.


Together, the electric powertrain can the prototype EV from 0 to 60 mph (97 km/h) in 3 s, and 0 to 100 mph km/h) in 5.1 s.

Structural batteries cut weight

Drayson said his team is also experimenting structural battery technology U.K.-based BAE Systems. which both save weight and energy storage capacity in versions of the car.

“The of the carbon-fiber composites not only load-bearing structure but operate as an storage device,” he explained. The of the two functions improves volumetric and efficiency as well as delivering flexibility in design and mass

Right now the development team is to incorporate structural battery into the rear wing.

The Manufacturing Group (WMG) at University. working in cooperation Lola, will provide new carbon fiber-composite body technology.

Battery charging is in the pit garage using coils in the car that are powered inductively contact by charge pads The wireless system is made by Halo. a spin-off from the of New Zealand. The current charging is static, but eventually the technology be able to power up the batteries on the track.

Another innovation is the application of regenerative damping technology Canada-based Multimatic of Markham, These suspension dampers energy when the driving-over-road are stored in a capacitor for later “The regenerative dampers produce a small but meaningful Drayson said.

During his travels, Drayson has heard older race enthusiasts whether electric racing is viable, citing issues the lack of the traditional engine of the racetrack and the like.

“But people, especially those in without an established motorsport such as India, China, and the East, don’t ask those he counters. “They know electric car technology is the future, and want to take part in
