Just last week, we heard reports that the KTM X-Bow would be getting a substantial power increase thanks to a new model using the excellent engine from the Audi TT-RS, but now its rival, the Ariel Atom, could be going in another direction for improved track performance. AutoCar is reporting that the open-wheel, open-top sports car could be getting an available all-titanium tube frame for a substantial drop in curb weight.

The article indicates that the weight of the chassis alone could drop by about 40 percent, which would lead to an overall dip in curb weight of eight percent. This would mean that the Atom's already spindly 1,350-pound curb weight could drop to less than 1,250 pounds. A titanium-framed Ariel would likely be a limited edition, according to the report, but it sounds like there are no plans to move the Atom away from its high-revving 2.4-liter four-cylinder sourced from Honda.

      This is going to be bonkers. Throw the V8 into this guy and it over for every other vehicle on the track. I think Top Gear might have a new car on its leader board soon.

      I still want to see an atom with an LSX/LS9 and AWD. Talk about the greatest way to die...

      Why not just go all carbon fiber? just as strong and even lighter.

      Why not aluminum? It would likely be just as light at half the price. I would like mine with a 2.0Turbo out of an ATS please.

        Aluminum loses its heat treatment when welded and soft aluminum is really weak. The only decent production aluminum frames are bonded. This frame does not lend itself to that type of construction. Titanium is very expensive and difficult to cut and weld, so there is a reason why tube frames are usually steel. I would love to see it in Ti, though. I also am curious if post heat treating of welded aluminum frames would be viable....

      I am making my own ariel atom with two bmw 1000cc engines out of their superbike. 400 horses out a 2.0 liter engine.

        And almost no torque..... :) Why not use a 4g63t or a 4b11t?

          Because it will be light enough that a turbo is unnecessary. ******* stupid Evo fanboys
          • 1 Year Ago
          Because nearly 400hp out of a 2 liter engine with no boost.
