McLaren abandons V8 and switches to plug-in hybrid V6 for its next supercar

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

And the Artura is really brand new. Previous McLarens, starting with the MP4-12C, have all used variations of the same carbon fiber monocoque chassis and derivatives of the same V8 gasoline engine, either in 3.8L or 4L capacities. Instead , the Artura will use a new platform, called McLaren Carbon Lightweight Architecture. And the powertrain is also entirely new.

The internal combustion component is a 3.0L, 120-degree, twin-turbocharged hot-vee V6 with an output of 577 hp (430 kW) and 431 lb-ft (584 Nm). McLaren says that, at 353 lbs (160 kg), this new engine – codenamed M630 – weighs 243 lbs (110 kg) less than the V8, in addition to being significantly shorter.

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

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

19 miles at 25mph

Unlike McLaren’s previous hybrids (the aforementioned P1 and the newer Speedtail), the Artura’s electric motor is able to propel the car on its own, with an electric range of only 30 km, albeit at speeds going up to 25 mph (40 km / h). And similar to those earlier McLaren hybrids (non-pluggable), the electric motor also provides “torque fill”, where it’s used to supplement the output of the V6.

McLaren managed to reduce the weight of the Artura, despite adding an electric motor and a battery. With a dry weight of 3,075 lbs (1395 kg), the PHEV Artura compares favorably with non-hybrid supercars like the Ferrari F8 or Lamborghini Hurácan.

The tech upgrade isn’t limited to the Artura’s powertrain. On the one hand, there is a suite of advanced driver assistance systems, including adaptive cruise control. And there’s a new infotainment system that now features Apple CarPlay and Android Auto functionality, along with McLaren apps like Track Telemetry. The car is even fitted with new Pirelli P Zero Corsa tires with what the rubber company calls “Cyber ​​Tire” technology, which combines software and hardware in the tires that “generates a high-value data feed based on on specific tire conditions relayed to Artura’s control systems to deliver the best tire performance. “

Deliveries are expected to begin in Q3 2020, and in the US, the Artura starts at $ 225,000.
