Everyone's favourite space-frame road-rocket is back, and this time it gains a new power plant.
This is the Ariel Atom 4, with the British automaker saying it is all new except for the fuel cap and brake/clutch pedals, which have been carried over.
Thanks to a newly engineered tubular chassis - with longer main and diagonal tubes – stiffness is up 15 percent over its predecessor. There’s also a bigger fuel tank, meaning a larger range, but most importantly, it gain's the Honda Civic Type R's new K20C motor.
Power stays constant, but Ariel have managed to massage an extra 20nm out of the motor by using their own ECU, with outputs now standing at 235kw and 420nm. Power is sent to the rear wheels of the 600kg-odd Atom via a 6-speed manual transmission and LSD. It also gains the launch control and traction control systems from the Ariel Atom V8, meaning the Atom 4 is capable of 0-100kph in 2.9 seconds, and 0-160kph in 6.8 seconds before topping out at 261kph.
The Atom 4 rides on larger wheels and standard Bilstein dampers, or an optional Ohlins suspension. There are also optional carbon-fibre wheels on offer, which apparently cut the weight of its wheels by 50%. Whatever little bodywork it does have, is made of carbon-fibre and has been tweaked to not only increase downforce and lower drag, but also to optimize airflow to the radiator, intercooler and air intakes.
The Ariel Atom 4 is set to make its public debut at this weekend's Goodwood Festival of Speed, before going on sale in the UK early in 2019, with a price tag of £39 975 (ZAR 715 000).
