Ariel Atom 3 by Wimmer RS – Click above for image gallery

It doesn't get much more extreme than the Ariel Atom. But Wimmer RS has managed to do exactly that.

The German tuning house has taken the Atom 3 and boosted output of the 2.0-liter turbocharged Honda four up from 300 horsepower to 340. The engine mods are carried out by a remapped ECU, rebuilt compressor and new fuel pump and exhaust with Rennkat converter. The extra power coupled with the same low 1,034-pound curb weight, the Wimmer RS Atom is capable of rocketing to 100 km/h (62 mph) in a scant 2.8 seconds and on to 200 km/h (124 mph) in 7.1.

That's mighty quick no matter which way you look at it, and look at it you may in the image gallery below, with full details in the press release after the jump.

Extra power - high performance sports car Ariel Atom 3 300 by Wimmer RS
Wimmer RS has tuned the Atom 3 300 up to 340 hp

The Ariel Atom is one of the fastest street cars, maybe the strongest sprint 4-cylinder series car in the world. The standard Atom 3 300 is driven by a turbocharged up to 300 hp two-liter four-cylinder Honda engine. With a weight of only 469 kg, it can easily keep up not only with super sports cars - after the power increase at Wimmer RS it can put some of them in the shade.

A vehicle like a rocket: only 469 kg weight, no doors, no luxury. The Atom is equipped with the unique internal shock absorbers. The suspension is operated via push-rods - the damper struts are at the top. The tube frame replaces the body. This provides rigidity, low weight and maximum safety for corner speeds.

The power increase at Wimmer RS includes the following reconstruction measures: Wimmer engine optimization software, compressor overhaul, fuel pump conversion and sport exhaust system together with Rennkat. Whopping 340 hp and 282 Nm are the result. With such powerful Japanese engine in the rear, this 469-kg rocket accelerates from zero to 100 km/h in 2.8 seconds - Atom achieved 200 km/h in just 7.1 seconds

Direct air suction sounds like a hissing, and by this modification, exhaust system with optimized back pressure from Wimmer RS allows to hide the entire power behind the seat, so you will hear a wonderful sound.

      top speed says top gear USA might be doing a comparison between Ariel atom and vortex F1 should be good.

      Do want

      Look at the back of the car. Do you see a turbocharger there? You got you info wrong (along with several other sites posting about this). They probably did some tuning on the supercharged Honda but it isnt turbo charged unless it is a "before" picture
        • 4 Years Ago
        A supercharger on such a light car helps with the learning curve since the torque curve is flat. But once I learned to handle the car, Im much happier with the turbo. Much more power without having to struggle to keep it running cool.
        • 4 Years Ago
        agreed, sth. went wrong there. the funny thing is that they mentioned a rebuilt compressor (the german word for supercharger) in the next sentence...

        the combination of such a light trackcar car and the nonlinear power output of a turbocharged engine just doesn't match imo.

      Would love to see a GM lnf motor in this car

      This is very cool.

      But there are better... like the Atom powered by the Hartley H1 V8.

      Or the SDR Sportscars WR3 V-Storm with a Subaru turbo boxer and longitudinal driveline.

      340hp is a *mild* tune (as in as simple as an ECU flash) for an STI-grade EJ25 turbo, or even a closed-deck EJ22 block, and there are Cosworth parts available to turn it into a dry-sump engine, and mount it even lower to the ground than it already is.

      And as far as interesting engines go... it would be interesting to see one with a well-built mazda 13B upgraded turbo rotary installed, too. On a race car, who cares about fuel and oil consumption, and the service intervals are pretty much expected anyway... but light weight, and revving to the sky would be a matter of course. A rotary is somewhat well suited to be a race engine more than a daily-driver, anyway.

        the subaru boxer engines are only mounted longditudinal, none are transverse
        • 4 Years Ago
        The V8 is totally bonkers fast, I think it may be one of the fastest road legal(UK/EU) cars you can buy. I've owned a Caterham in the past but nothing prepared me for a blast in a friends Honda Type R engined Ariel Atom and yes you do need to wear a helmet whilst driving it. Best descibed and treated as a four wheeled motor bike that dosen't fall over in corners because they handle very well on the twisty bits as well.
      • 4 Years Ago
      Yeah, like the car wasn't fast enough before, right?
      To be honest, I really don't put this in the same class as a true "car". Personally, it's more of a super go-cart.
        • 4 Years Ago
        Super go-kart or not, I want one.

        Extra power is always nice as long as you can put it down.
      • 4 Years Ago
      Yea I got a 09 ss sedan with the lnf and I love that motor
      • 4 Years Ago
      I always say I am going to buy one of these used in the future rather then a bike.
      • 4 Years Ago
      oh boy simplecar is going to love this
        • 4 Years Ago
        i get down-voting a annoying comment, but is there any need to bait strangers?
        • 4 Years Ago
        And you don't?
      • 4 Years Ago
      There isn't a lot that I wouldn't do to own one of these.

      I'd even promise to make it my DD for the next 5 years. Rain, sleet, snow, cold, I don't care, I'll drive it.
        • 4 Years Ago
        They are allowed at Summit Point, that is where I run mostly. I am pretty sure they are allowed at VIR at some HDPEs as well.

        I was riding in a friends track prepped C5 Z06 running on hoosiers and we were passed like we were standing still in a Atom 300. This was at Summit Point.

        I've seen a street legal one a couple times around here in the NoVA area.
        • 4 Years Ago
        I'd agree, but I realized that I couldn't drive it much of anywhere. It's not street legal if you buy the car built as opposed to getting the kit and assembling it yourself, and a lot of tracks and HPDE organizations near Austin don't allow the Atom because they classify it as an open-wheeled vehicle.

      This car owns all!
