In another major point of difference, the Ferrari has a normally aspirated 6.3-litre V12 engine (a developed version of its F12 unit), whereas the McLaren has a twin-turbo 3.8-litre V8.
The pair’s performance is closely matched, with 0-60mph times of around 3.0sec. However, Ferrari claims a 0-300km/h (186mph) time of 15.5sec, a cool 1.5sec faster than the “around 17.0sec” claimed for the McLaren. On the other hand, Ferrari fails to quote a top speed, “because it doesn’t matter”, whereas McLaren is quite specific about its car’s 218mph top end.
Ferrari claims a simulated Nürburgring lap time of less than seven minutes and says F1 driver Fernando Alonso has lapped Fiorano in 1min 19sec on Pirelli P Zero road tyres, whereas the 599XX could do 1min 16sec on slicks. On those tyres, LaFerrari is expected to be faster still.
The Ferrari is around 110mm longer than the McLaren at 4702mm, and about 50mm wider at 1992mm, but a surprising 54mm lower at 1116mm. It also claims a relatively radical 59 per cent rearward weight bias, which engineers label “just about ideal” for a car like this. Ferrari also talks about a “compact” wheelbase of 2650mm and claims that careful packaging of major masses between the wheels allows the centre of gravity to be an impressive 35mm lower than an Enzo’s.
The driving position is similar to that of a single-seater and was designed after consultations with Alonso and team-mate Felipe Massa. The chassis tub is to be made in the autoclaves of Ferrari’s racing department, using four different types of hand-laminated carbonfibre and incorporating components such as seat bases and battery compartment into the main structure, whose torsional rigidity and beam strength is up 27 per cent and 22 per cent respectively against an Enzo.
LaFerrari’s styling — penned by Ferrari’s own design team under Flavio Manzoni, with no hint of input from the Pininfarina design house that has produced the majority of Ferrari shapes — is more angular than the swoopy P1 but is dominated by the dictates of the wind tunnel. The front splitter appears to hang from a single front pylon — a nod to F1 — and the air intakes are huge. However, Ferrari says there is still room to acknowledge the “gloriously exuberant” Ferrari sports car shapes of the past via the low bonnet and muscular arches.
The cabin, believed to be more race-orientated than luxurious, has an F1-style steering wheel whose driving mode manettino offers five different driving modes instead of the usual four.
The car uses sophisticated aerodynamics that deploy automatically according to speed and attitude. There are moveable diffusers and a guide vane underneath the car, plus more moveable components on the rear wing. Ferrari’s aero experts say their brief was to deliver “the highest degree of aerodynamic efficiency ever achieved with any road car”, a claim likely to cause lively debate in Woking, where the P1 has been built to generate a maximum of eight times the downforce of the existing MP4-12C supercar.
LaFerrari pips the P1 on kerb weight. Ferrari quotes 1255kg for its car, although this is a ‘dry’ weight without oils or fluids added. The HY-KERS system contributes 140kg to LaFerrari’s total mass, 62kg of which is down to its centrally mounted battery pack. The remaining mass consists of control systems, wiring and a pair of electric motors, one mounted on the back of the seven-speed dual-clutch automatic gearbox to contribute drive to the car, the other to drive ancillaries instead of powering them directly from the engine.
The battery is charged via regenerative braking and whenever the engine produces excess torque, and its smart ancillaries work the same way. The P1, by contrast, has a single electric motor that mates so closely with its petrol turbo V8 that the crankcase casting is specially shaped to accommodate it, but it lacks regenerative braking.
On the other hand, Ferrari’s HY-KERS does not have the McLaren’s electric-only drive mode for zero-emissions traffic zones, which leaves it with an official CO2 figure of 330g/km that compares poorly with the McLaren’s. However, Ferrari says an electric-only mode can be engineered into the car for customers who really want it.
The Ferrari has a mid-mounted normally aspirated 6262cc V12, closely related to the F12’s engine but with new internals. It produces 789bhp, with a redline of 9250rpm. Add 161bhp for the electric motor and the driver has total command of 950bhp, along with peak torque of 715lb ft. Both outputs exceed the P1’s figures by about 10 per cent, an advantage hardly reflected in the comparative performance until the cars are above 150mph.
Ferrari has announced a price and revealed that 499 cars will be built, but it has yet to announce a date for first deliveries, although autumn is tipped. This is a two-year programme, Maranello says, and while the majority of cars already have owners, some are still available.
