McLaren drops the V8, moves to V6 plug-in hybrid for its next supercar

McLaren unveiled its latest supercar, the Artura, on Tuesday night. This is the company’s first built-in hybrid EV, which promises all the usual performance superlatives associated with McLaren: 0-124 mph (200 km / h) in 8.3 seconds, a quarter-mile time of 10.7 seconds and a top speed of 205 mph (330 km / h). h) put it in good company with the rest of the brand. But it should also be the most efficient McLaren to date, with only 129 g / km CO2 according to the EU’s WLTP test.

And the Artura is really brand new. Previous McLarens, from the MP4-12C onwards, all used variations of the same carbon fiber monocoque chassis and derivatives of the same V8 petrol engine, whether in 3.8 liters or 4 liters. Instead, the Artura will use a new platform called the McLaren Carbon Lightweight Architecture. And the driving force is also completely new.

The internal combustion component is a dual turbocharged 3.0L 120-degree ‘hot-sweep’ V6 with a output of 577 hp (430kW) and 584Nm. McLaren says that this new engine, codenamed M630, weighs 160 kg (110 kg) less than the V8, and is also significantly shorter.

But the V6 is only half the story; it’s a PHEV after all. So there is an axial flood electric motor of 94 hp (70 kW), 166 lb-ft (225 Nm), which according to McLaren is denser than conventional radial flood motors. In fact, McLaren claims that the Artura’s electric motor has 33 percent more power density per kilogram than the electric motor used in the P1 hypercar. The electric motor also functions as the Artura’s reverse gear – the forward movement from the engine or the electric motor is via an eight-speed dual-clutch transmission.

The electric motor is connected to a 7.4kWh liquid-cooled lithium-ion battery pack, consisting of five modules and mounted behind the monocoque. The batteries can be recharged by excess power from the engine while driving; connected to an AC wall charger, the car (according to McLaren) should take 2.5 hours to reach the 80 percent charging state.

19 miles at 25mph

Unlike McLaren’s previous hybrids (the above P1 and the recent Speedtail), the Artura electric motor can drive the car on its own, with an electric range of only 30 km, although only at speeds of up to 25 km / h. u (40 km / h). And similar to the earlier (non-plug) hybrid McLarens, the electric motor also offers ‘torque filling’, where it is used to replenish the V6’s output.

McLaren managed to keep the weight of Artura, despite the addition of an electric motor and a battery. With a dry weight of 1,395 kg, the PHEV Artura compares favorably with non-hybrid supercars such as the Ferrari F8 or Lamborghini Hurácan.

The technical upgrade is not just limited to the Artura drivetrain. First, there is a range of advanced driver assistance systems, including adaptive cruise control. And there’s a new infotainment system that now has Apple CarPlay and Android Auto functionality, as well as McLaren apps like track telemetry. The car even features new Pirelli P Zero Corsa tires with what the rubber company calls “Cyber ​​Tire” technology, which combines software as well as hardware in the tires that generate a stream of valuable data based on the specific tires. transferred to the control systems of the Artura to deliver the best tire performance. ‘

Deliveries will begin by Q3 2020, and in the United States, the Artura will start at $ 225,000.
