McLaren has used experience gained over the past decade to create a new carbon passenger cell, which no longer uses associated steel reinforcements, and the windshield frame and B-pillar are made entirely of carbon, with energy-absorbing aluminum structures at the front and rear. The additional hybrid drive was compressed with a shorter motor and transmission, with the battery installed directly behind the seats in the floor. The suspension is an entirely new design, with the front upper swing arm attached to the carbon passenger cell, for example, and the lower part of the aluminum safety frame, with the battery case frame used as a support between the lower swingarm contact points.
A special feature of the 3.0-liter V6 twin-turbo engine is the large cylinder angle of 120 °, which was necessary because the turbine is now inside the V. The block and cylinder head are 3D printed, so that the coolant and oil channels have a particularly impressive interior, for example A 2 mm wide radiator channel between the cylinders. The resource is made entirely of aluminum, there are no bushings, and the holes are specially processed. The V6 twin-turbo engine produces 585 hp (7,500 rpm) and a maximum torque of 585 Nm (2,250-7,000 rpm). The newly developed dual-clutch transmission has eight gears, the reverse gear is saved – the car moves in reverse with an electric motor rotating in the opposite direction – and an electric motor with a power of 95 hp / 225 Nm (constant power 50 hp) is installed. System power is 680 horsepower and system torque is 720 Nm.
With constant weight savings, despite an additional 130 kg hybrid engine, we were able to keep our weight under 1.5 tons – 1395 kg dry in dry weight – the Artura is lightning fast. Acceleration from 0-100 km / h lasts 3.0 seconds, acceleration from 0-200 km / h 8.3 seconds, 0-300 km / h 21.5 seconds, top speed is electronically limited to 330 km / h – a quarter mile distance is completed by Artura in 10.7 a second ; These aren’t bad values for a purely rear wheel drive car. Deceleration is also noticeable, with a braking distance of 126 m at 200 km / h and only 31 m at 100 km / h.
With a lithium-ion battery with a useful capacity of 7.4 kWh, an electrical range of up to 30 km can be achieved, but on the other hand, it has not been revealed whether it is less realistic than the NEDC or a more realistic WLTP standard. In electric mode, the maximum available speed is 130 km / h.
The car has a completely new electrical system, which results in new and faster driver support systems, but also due to the advent of the electronic differential lock and the fact that the head unit actually provides wireless connection to the phone. There is more space in the passenger compartment than before, and the instrument cluster does indeed move with the steering wheel when it is modified, so the engineers made sure everyone could see the tools well. The center display is slightly oriented towards the driver and by default you can choose from three interior modes, individual needs will be catered for by MSO. The McLaren Artura is now available at dealerships in the UK for £ 185,500 or £ 76.5 million.
