British supercar-maker McLaren today proclaimed ‘a new era’, as its 212mph 720S model became the first of its second-generation Super Series
The 720S accelerates from rest to 60mph in just 2.8 seconds compared to 2.9 seconds for the outgoing car. And hitting 124mph takes the 720S just 7.8 sec compared to 8.4 seconds for the 650S.
It has a bigger engine – a 4.0-litre twin turbo V8 – that develops the 720 horse-power which gives the new car its numeric name.
That compares the the 3.8-litre twin turbo in the 650S which similarly develops 650 horse-power.
As a result the 720S’s 212mph top speed is 5mph faster than the 207mph achieved by the 650S.
1. The new, twin-turbocharged 4.0-litre V8 engine produces 720PS and 770Nm with a power-to-weight ratio of 561PS per tonne.
2. 41% of the engine is made up of new parts compared to the 3.8-litre engine that feature in other McLaren Sports Series models.
3. The carbon fibre chassis keeps the weight down to 1,283kg.
4. There are no radiator intakes on the side of the car. Instead, this function is carried out by the unique ‘double-skin’ aerodynamic form of the angled upward-opening ‘dihedral’ doors, which channel air to the high-temperature radiators that cool the mid-mounted engine.
5. 0 to 62mph takes less than 3 seconds and just 5 seconds later the car has passed the 124mph mark on its way to a maximum speed of 212mph.
6. It stops even quicker, taking 4.6 seconds to come to a halt from 124mph, covering 117 metres in the process.
7. CO2 emissions at 249g/km are also slightly lower than the 275g/km in the 650S – but still hefty by normal car standards.
8. The structure is based around a new carbon fibre tub and a 'Monocage'. McLaren says this technology 'delivers extreme strength and rigidity in a lightweight structure and is the ideal base for any supercar'.
9. The interior is hand-crafted using a blend of fine leathers and machined aluminium, with a folding driver display and central infotainment screen.
10. There’s space behind the seat-backs for two soft holdalls or carry on luggage bags – equivalent to 210 litres – in addition to the 150 litres under the front panel.
