SDR WR3 V-Storm – Click above to watch video after the break

Britain's kit car industry isn't just alive and well, it is hale and hearty if last year's Exeter Kit Car show is anything to go by. The newest home-built contraption is the SDR Sports Cars WR3 V-Storm. Like a number of other British cars most famously represented by the Ariel Atom, the V-Storm is basically scaffolding with seats and an engine.

The previous model was powered by the V-twin from an Aprilia RSV1000. The latest model gets its scoot from a Subaru Impreza engine with more than 300 horsepower, good for a run from 0-to-60 of about three seconds. The "3" in the WR3 moniker refers to the seating: a McLaren F1 style center position for the driver and two wingmen behind. Kits start at £3,995 ($6,534 U.S.), or £19,995 ($32,700 U.S.), plus VAT and fripperies, for a turn-key car.

      There's a good reason for Britain's kit car industry being in good health. In the UK small companies can be registered for limited type approval. This means the cars can be bought fully assembled, not just as kits. Obviously, this makes them a far more attractive purchase than having to spend a year or so in the workshop trying to put the thing together.

        Thanks Hoss! Maybe that's our path to the 100mpg car. Does anyone know any "Open Source" designs out there yet? Or affordable lil'kit cars that wouldn't need$5000 of batteries or 150KW electric motors. Pop in a high-compression (12:1) 1.6L Honda engine tuned to run on E85, 5 or 6 speed tranny, some homemade stop start pedals. Remove the alternator, remove the water pump and pray.

      Wow nice ICP sticker on the hood of that car. *immediately writes off story*

      Wonder if they offer an actual real roll bar. their bar seems pretty aesthetic. Not that the atoms stock bar is much better, but Ariel offers a functional one if you want.

      would it be possible to have this with something like a viper engine or the new mustang 5.0? add AWD drive to that and it would be perfect
        • 5 Years Ago
        yea, i wasn't sure about the mechanics of it, i just thought it would be an amazingly fun car
        • 5 Years Ago
        This is already a RWD, Mid-engined car powered by a WRX STI.

        The STI motor already makes an easy 300+hp and torque stock, and can do more with tuning. Like 400-450hp with the right parts. And probably significantly lighter than a big V8 engine, and certainly FAR more compact, and lower to the ground, not to mention the engine being half as long.

        AWD would be a challenge, to route a driveshaft 180 degrees around, under the transaxle and engine, and under the whole chassis... and with a light front end, it wouldn't add that much traction, for the weight it would cost, and would likely numb the razor sharp steering a bit.

        AWD on a road car is a bit of a different set of compromises than putting it on a race car like this.

        And this isn't exactly a car to drive in inclement weather, or ice and snow, anyway. With a Mid-engined weight bias, as long as the rear tires are properly sized and the suspension is as good as it claims... traction should be fine for the chassis' capabilities.

        Dropping the clutch and hammering on it will certainly smoke the tires, but otherwise, this car should be seriously quick, still quite light weight, and with good amounts of grip.

        It may be possible, but with those tire sizes and weight, you're going to mostly just be spinning the tires. AWD is just going to add weight, and isn't optimal for an american V8. It could work, but the increased delicacy of AWD over a good RWD setup makes it more vulnerable to engines with significant low end torque.

      Use a couple of covers where your passengers are at and, bam, cheap open-wheel track-day car.
        • 5 Years Ago
        The chassis is actually modular, and can be sized down for a single driver, in the construction stage.

        OR, supposedly the company is developing shell covers and alternate bodywork for what you describe, also. There is also a suggestion that SDR is developing a roof-skin and windscreen version of the car's bodywork.
        • 5 Years Ago
        I know I am in the minority here, but why can't someone take this or this idea, stick body panels around the passenger compartment, stick a roof and windshield and throw in an electric motor.

        With light weight, you would get oh so much more mileage out of one between charges, rather than the burden of a full car. much more entertaining commuter car than a Smart.

      Now I know what to get for light attack vehicles once Mad Max comes around. One Driver, two gunners in a small package that can out manuver just about anything? Yes, Please
        • 5 Years Ago
        @mda571
        Dune buggy suspension and rolling stock... and two mini guns mounted to the frame sides, for the rear seat gunners...

        I could see how that would work... :D
      • 5 Years Ago
      Sooo they basically just tried to make a direct copy of the ariel atom and then change the seating? Or are they actually getting the frame from ariel?
        • 5 Years Ago
        A trellis frame is not original to Ariel, either. One could take inspiration from almost any ground based antenna mast.

        There is a little graphic similarity, no doubt. but the construction type is kinda dependent on that spatial arrangement. Otherwise it would be a composite monocoque, or some other design.

        A steel trellis, especially optimized for minimum tube lengths but maximum rigidity, and thus minimum weight, is going to come out looking like this time and time again.
        • 5 Years Ago
        Good point with the Cobra. Regardless, I think that I would be a bit frustrated if I was an engineer at Ariel. I mean, its not like SDR thought up that frame design on their own...
        • 5 Years Ago
        No, their website shows that the frame is custom made for this car, it is wider than Atom, and is CNC cut tubing and milled intermediate members for suspension attachment.
        http://www.sdrsportscars.co.uk/home.html

        It is much like the Atom, but it isn't a direct copy. It originally used an Aprilia V-twin motorcycle engine, and now uses a longitudinal WRX STI turbocharged boxer engine drivetrain.

        Ariel Atom uses a transverse FWD-style drivetrain in the mid-engine position.

        Just as a contrast... how many kit car companies copy the 427 Cobra? Yeah. a lot.
      • 5 Years Ago
      it would be fun to scare the crap out of the kids with - they need to fix that ugly snout.........
      • 5 Years Ago
      so, for the most basic kit, how many pieces does it come in? how much work would it take to fully assemble?
      • 5 Years Ago
      Subaru STI power, with an STI 6-speed converted to lateral RWD/Mid-engine... This thing is likely SERIOUSLY quick.

      I have wanted to build a car with that layout for so long... but always wondered what gearbox to use. Porsche/VW gearboxes required adapters...

      And the car itself looks well built, and the 1+2 seat layout, like a McLaren F1 makes a lot of sense here.

      I hope there is a significant chance of this being imported.
