Last year, Drayson Racing and Lola announced they would partner on an all-electric race car and now, at the 6th MIA International Low Carbon Racing Conference, the very impressive result of their collaboration has been revealed. The Lola-Drayson B12/69EV is an 850-horsepower (640-kW) monster that will seek to destroy many an electric vehicle speed record this year, while simultaneously serving as a development platform for a different design Drayson Racing will bring to the 2013 FIA Forumula E series.

If, however, a racing series is announced that will accept the Lemans-style prototype as is, they might very well campaign it. It should be interesting to see then, if the just-announced ALMS-IMSA-Quimera initiative might be a viable option for them. With projected acceleration numbers of 0-to-60 miles per hour in 3 seconds, 0-to-100 mph in 5.1 seconds, and a top speed somewhere north of 200 mph, it should be pretty competitive.

The B12/69EV gets all that motive power from four YASA-750 axial flux motors running on a 700-volt system. The 60-kWh battery setup that provides the asphalt-sizzling energy consists of three separate packs of A123 cells – cylindrical ANR26650M1-B's sourced through Mavizen, to be exact – that are structurally integrated into the Lola carbon fiber chassis. Charging is also appropriately high tech, using an inductive system from Qualcomm Halo.

Besides an incredible amount of power and torque, the racer weighs in at about 1000 kg (2205 lbs), which is within 100 kg of a typical internal combustion LMP1, so handling should be pretty similar. Of course, the proof of the racecar pudding is in the driving and we look forward to seeing this machine in action once video is dished out.

      And don't forget the adaptive aero package :-)

      It will run like a raped monkey, but for only about 10-12 minutes.

        @BipDBo
        uh...gross analogy. LOL Besides, it would run for about 17-20 minutes due to regen braking and the fact that they don't stay on the juice at 100% during the entire lap. But point taken, it would be short.

          ROFL Much better analogy! No worries, I'm sure he'd be drinking a diet coke. Great link, I forgot about those guys. But note that they measured that as the power from the grid, not the content of the batteries. So you can add ~10% to the distance they drove on the batteries themselves. Plus, I can't find the weight or any other specs like the Cd and frontal area for it. The aero measurements are hugely important for the energy used at high speeds. I'm hoping that with the active aero on the Drayson beast, that they can get much better efficiency at the higher speeds on the straights. Of course, now that I know they don't have 4 wheel regen, and considering that the Ring has lots of relatively long straights with flat-out running and less chance for regen, I'm definitely being to optimistic/wishful. I would still hope they could get 15 minutes or at least 2 laps in.

          Fine. It'll run like Bill Clinton with a gift gard to McDonalds. I figured I was being pretty generous with an estimate of 10-12 minutes. When track racing, you are basically slammed on the accelerator, or slammed on the brake, but most of the time, it's on the accelerator. You won't get a a big portion of your energy back through regenerative braking this way, either. The EV Raceabout, which has less than half the power (300 kw), lapped the Nürburgring in 8:42, using 25.6 kw*hr doing so. http://green.autoblog.com/2011/09/27/electric-runabout-clinches-new-nurburgring-ev-speed-record/

      640 kW electric motor. Interesting, got any better pictures?

        Motors...4 of them :-) One on each wheel so they have torque vectoring, true all wheel drive and all wheel regen braking.

        You can see pictures of them on their website (www.yasamotors.com). Also, our stories featuring Yasa Motors can be found at (http://green.autoblog.com/tag/yasa) I would point out that the car isn't actually AWD. It has four motors but they are sandwiched together in the rear of the vehicle and drive only the rear wheels.

          Thanks Domenick, I should have looked at the pictures more closely. That means they won't have as much control and they won't be able to do regen on the front wheels. Much less regen braking then and more energy per lap. Still great stuff, but one step at a time I guess.

          @Domenick
          Also, if it doesn't have AWD, and knowing it would still weigh1000kg in its current configuration, then it would still have a chance to break the 7 minute barrier, but I don't think it could get near the track record 6:11. But as Dan said...it would depend on the driver! It is amazing how much difference it makes to have someone like Sabine because she practically lived on the Ring :-)

      The batteries are more interesting than you would gather from the above: 'Traction power for the Lola LMP is provided by three Li-ion battery packs manufactured by Mavizen comprising li-ion battery cells made by A123 Systems. Additionally, the car features structural composite batteries (earlier post) from BAE systems—i.e., multifunctional structural composite material which can store and discharge electrical energy and which is also strong and lightweight enough to be used for car parts. BAE Systems has been investigating and demonstrating structural batteries and capacitors as part of recent projects funded by the UK Ministry of Defense as well as by the private sector. The projects demonstrate the feasibility of generating multifunctional materials and methods to convert inert structural elements into load-bearing, energy-storage media. BAE says that this approach enables the creation of energy storage devices with very high volumetric efficiencies that can be built into the structure of an object providing an integral battery to deliver greater design flexibility and distributed mass. BAE has eight patent applications filed or in progress on this technology that incorporates the chemicals that batteries contain directly into composites. For the Lola Drayson B12/69EV, structural battery technology offers the opportunity to house power for some onboard electronic systems within the structure, allowing the main batteries to be dedicated to propelling the car.

        hehe I'm not entirely displeased with it. but alas still not quite perfect. on the positive I think it will be a rather good racer. they should really run it at nurburgring asap to get it out of the realm of paper tigers. for it's power it has relatively slow acceleration to 100km/h but because it is direct drive we might expect that acceleration rate to continue towards its top speed which is where it really counts for a track racer so it might do very well. could it threaten the 7 minute limit.. scaring the ICE cars is the good stuff. the Yasa motors are interesting for this application. I don't as such like the 500kg A123 pack however, it's probably quite good for nurburg times, at least until a better design comes along but for racing I'd like to see a much smaller pack in a lighter car and have battery swap. the car weighs a ton and that is really much too much for what pretends to be an all out racer. a well built single seater racer should weigh maybe 100kg without drivetrain. it's so curious that it never occurs to them that weight is the enemy in some holistic sense. I guess it's born from the heavy combustion engine and then builds from there. and the human failure in thinking that more is better. if it breaks the 7 minute barrier on the ring I will spare its life : ) am I not merciful : ) for the ring they might try reducing the pack a bit so it only has enough for one lap. if they could shave off 100kg that way that has to matter. and put Jason Plato in it, he seems like a crazy intense driver. maybe also give Sabine a couple of tries. it's time she got out of those pathetic BMWs

        Imagine this thing on the 'Ring'! It will blow away 7 minutes without even breathing hard! pun intended :-) As you say, they could drop some weight, actually 250kg of batteries in this case, and make a lap of the ring. Those A123 cells can actually peak out at 20kW/kg so that would still leave them with plenty of power to drive those 640kW worth of electric motors and it would only take about 12kWh for this car to lap the 'Ring so the 30kWh left at 300kg would be plenty for even 2 laps. So it would weigh about 750kg, have 640kW of power, 4 wheel vectored drive and active aerodynamics. This compares to the current record holding Porsche 956 which weighs 800kg, had 474kW of power, only 2 wheel drive, and no active aero...and they ran 6 minutes, 11 seconds. This car will DESTROY the 7 minute barrier if they want to set it up and go for it. It make a bit of tweaking to get the balance right and work out the kinks...but this car would beat 7 minutes at the ring and most likely beat the 6:11 record once they get it tuned/balanced right. EVs are going to blow people away when they get these things really tuned out. I wonder how the ICE crowd will react when they get their A$$E$ kicked? I know it's only for 20 -25 minute sprint races right now, but it will keep growing.

          Maybe, though less battery means for same C rate less power (see "Why bigger battery options give Tesla Model S better performance" post). I missed the Toyota Motorsport GmbH EV P001's lap time of 7 mins 47.794 in August 2011, nicely done. "The TMG electric powertrain uses two electric motors to deliver peak power of 280kW and a top speed of 260km/h with zero emissions. That makes it ideal to power any future single-make electric motorsport series and TMG will begin commercial sales of its electric powertrain technology in 2012. Total weight of the two-seater sports car is just 970kg, including the lithium-ceramic battery which allows for nimble handling around the demanding Nordschleife, essential for setting a competitive lap record."

          skierpage, I'm fairly certain that the power would not be a problem. I don't have specs on this pack so we can only extrapolate from other known sources. But the A123 batteries they use in Formula1 only weigh 11kg yet put out 60 kW of power to the motor. So I'm assuming that 250kg of those batteries could put out MUCH more than 640kW. Of course, their system is spec'd at 700V so that would probably have to change but I can't be sure about that because I don't know for sure the cell size and arrangement.

          that's a rather aggressive prediction : ) 6:11 would certainly get attention. that would flip a lot of minds and help the cause a lot. your optimism is infectious : ) beating 7 would be a good start but if it can threaten all time records I'm all for it. the thought of heartbroken porsche engineers pleases me : )

          Actually the Lola-Drayson B12/69EV is rear-wheel-drive, not AWD. The four motors are configured in two "sandwiched" pairs in the rear of the vehicle (as per the technical drawing in the gallery). Torque vectoring will be limited to the rear wheels for now.

      If they added swap battery technology, range wouldn't be an issue.
