All-new Ariel Atom 4 gets Honda Civic Type R engine and arrives in 2019
The new Ariel Atom 4, the latest instalment in the British marque’s track car series, has been revealed. Despite the familiar aesthetic, the new model is ‘an entirely new car from the ground-up’. Four years in the making, it represents the ‘biggest change on the Atom since 1999’, according to Ariel Motor Company general manager Tom Siebert.
Just like its predecessor, the Atom 4 boasts impressive headline performance figures: 0-100km/h is dispatched in 2.8sec, 0-160km/h takes just 6.8sec and it’ll reach a 260km/h top speed.
Honda supplies the engine, which comes from the Civic Type R, marking a switch from supercharged to turbocharged power for the Atom. Siebert explained the move was forced to satisfy emissions standards. ‘With the previous car, the Honda engine was only Euro 4 so we couldn’t have gone for type approval even if we’d have wanted to.’
In this application the 2-litre four-cylinder engine develops 238kW and 400Nm of torque, representing increases of 7kW and 170Nm respectively over the Atom 3.5; bespoke engine mapping, a stainless steel exhaust and the 4’s unique intake deliver the 3kW advantage over the Type R.
To best deploy the performance, Ariel has calibrated the Atom’s ECU to accommodate both traction control and launch control (which are optional extras), and has also installed a (turbo) boost controller.
The tubes forming the all-new chassis are larger in diameter, and have been designed to create the lightest, yet strongest structure possible. As a result torsional rigidity is up 15 per cent compared to the 3.5.
