McLaren has just uncovered the new Artura GT4 racer, prior to this week’s public premiere at the Goodwood Festival of Speed (June 23-26). Set to be put through its paces on the famous Hill Climb by the company’s factory driver Rob Bell, ahead of the intensive testing and development program before the 2023 season, it replaces the 570S GT4.
Sharing much of its technology with the road-legal Artura, the new GT4 features motorsport-inspired chassis design and construction, and packs a compact V6 engine. While the twin-turbo in the regular Artura is electrified, the GT4 racing requirements do not permit hybrid powertrains, so it makes do without these components, a measure that has helped it shave 130 kg (287 lbs) from its total weight.
Operated via a Bosch Motorsport ECU, the V6 boasts improved throttle response and better fuel economy over the V8 powering the 570S GT4, even without any electrification whatsoever. On top of that, the mill enhances the power-to-weight ratio and lowers the center of gravity, thus improving the handling of the Artura GT4 compared to its predecessor. Power is delivered to the wheels via a seven-speed transmission, different than the eight-speed one found in the road-legal Artura.
Better aerodynamics and downforce are two more key aspects of the racer. It has a bespoke splitter, hood duct, dive planes, and adjustable wing at the rear, mounted to the chassis using a new ‘G-Pylon’ design. This means that the rear bodywork can be removed without dismantling the wing. Removable hood for ease of access and a 110-liter (29-gallon) fuel cell, with a main pump, and two motorsport lift pumps, are other highlights of the build.
Fixed driver’s seat with adjustable pedals, steering wheel with illuminated buttons, and Bosch DDU instrument display with enhanced graphics are found inside. Customers will be able to order several optional extras, including a passenger seat and harness, data pack, V-Box telemetry, collision avoidance system, and tire pressure monitoring. The extra lights for night racing, drinks system, and left-hand fuel fill, and air jack lance are available, too.
