“A” is for Artura at McLaren

McLaren has been a lot of things in its existence including a dominant force in Can-Am competition, a revolutionary arrival at the Indianapolis 500, a champion in Formula 1 and to help pay the bills, the purveyor of million-dollar megacars. Like many manufacturers, McLaren, a wellspring of leading-edge British technology, is pivoting to embrace the growing market demand for carbon-neutral road vehicles. McLaren’s response is this week’s introduction of the Artura, the first in what McLaren posits will be an expanding High-Performance Hybrid series of supercars. The Artura is indeed a full hybrid, motivated by the combination of an all-new, twin-turbocharged 3.0-liter V-6 with four powertrain modes plus an axial flux electric motor, lithium-ion battery pack and a new eight-speed transmission powering the rear wheels. McLaren assures a 0-60 time of three seconds flat and an electronically limited top end of 205 MPH.

The Artura is the first McLaren road car to incorporate the British firm’s new McLaren Carbon Lightweight Architecture (MCLA) in its underlying design. McLaren operates a composites research center in Sheffield, England, which creates substructures specifically to accommodate the HPH line of powertrains as it develops. For the Artura, the MCLA strategy incorporates a central carbon-fiber safety cell for the occupants, with that monocoque fitted to alloy structures for the chassis/suspension components, with the other subframe dedicated to electrical architecture. The electrical structure incorporates ethernet capability that reduced the necessary amount of electrical cabling by 25 percent, while simultaneously controlling the vehicle’s HVAC system electronically. The narrow 120-degree V-6, with both turbos positioned in its valley for still better packaging, produces 430 horsepower on its own, not factoring in the electrical boost.
