The hybrid supercar's performance times have now been verified by McLaren.
It's been a couple of months since the McLaren Artura was shown to the world, the automaker's first series-production hybrid supercar. Replacing McLaren's renowned twin-turbo V8 is a new hybrid setup consisting of a 577-hp twin-turbo 3.0-liter V6 and an electric motor. Combined, this setup generates 671 hp and 531 lb-ft of torque. Since its debut, the Artura's astonishing acceleration times have been officially verified by McLaren.
0-60 mph in the Artura takes three seconds, while 124 mph is achieved in just 8.3 seconds from a standstill. It also takes just 21.5 seconds for the Artura to rocket from 0-186 mph before it maxes out at an electronically limited 205 mph. With this setup, the Artura will blitz the quarter in 10.7 seconds.
"The McLaren Artura's all-new, super-lightweight electrified powertrain is at the cutting-edge of high-performance-hybrid technology, engineered to offer all of the advantages of internal combustion and electric power in one package and establish new benchmarks for combined performance and efficiency in the supercar class," said Geoff Grose, Chief Engineer at McLaren. "The 'clean-sheet' design of the Artura has allowed us to focus on how to make this power accessible to the driver and deliver the levels of engagement expected from a McLaren."
Reducing weight was a key priority for McLaren when designing the powertrain. The 120-degree twin-turbo V6 was originally going to be 180-degrees, but this would have increased the height of the crankshaft and the center of gravity.
Compared to McLaren's twin-turbo V8, the new V6 engine is 7.4 inches shorter and 8.6 inches narrower. Power is sent to the rear wheels through a new eight-speed seamless shift transmission with optimized packaging. The cylinder head and block also utilize 3D printed cores, while the electric motor is similar in size to a McLaren brake disc and weighs 33.9 pounds, making it only slightly heavier than a conventional iron rotor component.
Providing the juice is a 7.4 kWh battery enabling the Artura to travel on pure electric power for up to 18 miles. To optimize the car's center of gravity, the battery is positioned behind the driver and incorporated into the floor. Using an EVSE socket, the battery can be charged from zero to 80 percent in just 2.5 hours.
Deliveries for the McLaren Artura will start in Q3, 2021, with pricing starting at $225,000.
