The Artura is the first McLaren to be truly new since the the MP4-12C supercar nearly a decade ago. Riding on the new McLaren Carbon Lightweight Architecture (MCLA), the carbon-fiber tub replaces the automaker's MonoCell design that started life in the MP4-12C. Rivals Ferrari and Lamborghini utilize aluminum construction for their lower-level models. The MCLA was designed from the start for electrified powertrains, and the platform will be utilized in future McLarens.
A twin-turbocharged 2.9-liter V-6 produces 577 hp and 431 lb-ft of torque. At 353 pounds, it weighs 110 lbs less than McLaren's twin-turbo V-8 and is shorter for better packaging, which is aided by dry sump lubrication. The aluminum engine can rev to 8,500 rpm, which is just 500 rpm shy of the 2022 Porsche 911 GT3's naturally aspirated 4.0-liter flat-6. The gas engine is paired with an electric motor located in the 8-speed dual-clutch automatic transmission that adds 94 hp and 166 lb-ft of torque. Total powertrain output of 671 hp and 531 lb-ft of torque is sent to the rear wheels via an electronically controlled differential also mounted within the transmission.
The Artura utilizes the electric motor to reverse the car by spinning in the opposite direction. There is no reverse gear in the transmission. Neat trick.
At 3,303 pounds, the Artura is no heavyweight, but McLaren said it packs a punch with a 0-60 mph sprint of 3.0 seconds, a 0-124 mph blast of 8.3 seconds, and a 0-186 mph run of 21.5 seconds on its way to a top speed limited to 205 mph.
The 7.4-kwh lithium-ion battery pack that powers the electric motor provides the Artura with up 19 miles of all-electric range. McLaren said the system can be charged up to 80% in 2.5 hours on a 240-volt outlet, though the battery can also be recharged via the gas engine while driving via various drive modes.
McLaren provides four powertrain modes: E-mode (all-electric mode), Comfort, Sport, and Track. Independently controlled handling modes adjust the dampers and electronic stability control system.
In a bid to provide feedback from the road, McLaren sticks with a hydraulic power-steering system. Every Artura will come with carbon-ceramic brakes and aluminum calipers to save unsprung weight and deliver track-ready stopping performance.
The tech, and all the lengths McLaren has gone to keep the car light,is pretty cool however. As mentioned earlier by another member, I dig the idea of using the electric motor for reverse gear. I just wonder if the car has a proper gear in the event the electric motor is out of juice.

As for running out of juice, I think that's easily solved by the onboard computers limiting battery depletion to a certain % so that you always have some juice to reverse out.
