Since the launch of its unfortunately named MP4-12C sports car in 2011, McLaren Automotive has built every vehicle using a version of the same carbon fiber chassis and V8 engine. A decade later, McLaren is launching version 2.0 of the company’s product line, with a new hybrid-electric V6 powertrain bolted into an all-new carbon fiber chassis tub structure.
The howling turbocharged V6 engine would have been right at home in Prost and Senna’s ‘80s turbo-era McLarens, though at 3.0 liters, the Artura’s engine is double the size of the power plants in those old race cars. Senna would have envied the alacrity of the Artura’s shifts in comparison to the H-pattern transmission of his F1 car at that time.
and heads. The features inside this engine are too small to create by conventional techniques, according to Grose. “It allows the shortest possible gaps between the cylinder bores, just 2mm,” he says. “That is a really tight, thin core. This 3D printing technology is really good for enabling that.”Computer optimization modeling apparently points to this 120-degree turbo V6 engine layout, as it is the same arrangement Ferrari reached for the 296GTB, that company’s analog to the Artura.
However, the steering wheels on race cars never turn so far that the driver has to reposition their hands, so they can always click up with the right paddle and down with the left. Street car steering wheels, on the other hand, crank through a couple turns from one side to the other, leaving the driver with no idea where the shift paddles are when turning. However, it is unusual to do much shifting while turning so much, so maybe this quirk doesn’t really matter.
Speaking of turning, you’ll need to slow the Artura down from time to time, and McLaren continues to set the industry standard in brakes. While Lamborghini’s carbon ceramic brakes are comfortable to drive on the street, they get vague and imprecise on the track. Other brands like Ferrari and Porsche deliver on the track, but their carbon ceramics are grabby and squeak embarrassingly in street driving.
