10 Things You Need To Know About The New Ferrari SF90 Stradale
Right now, I should be telling you what the Ferrari SF90 Stradale is like to drive. I can’t wait to find out where Ferrari has taken hybrid technology in the six years since the LaFerrari.
Three electric motors rather than one, 25km electric range, a combined 1,000hp, Ferrari’s fastest, most powerful road car ever. However, travel restrictions across Europe mean I haven’t been able to get to Maranello to drive it yet.
But having spent a good proportion of an evening on a conference call to the engineers and designers, I do now know quite a lot about it…
The SF90 Stradale is a new kind of crossover, a car that bridges the supercar/hypercar divide. Technically it’s moved the game on from the LaFerrari – it’s more powerful and advanced but, crucially, it’s not a limited edition model, but a full production car.
Ferrari claims ‘only’ 90 per cent will be sold to existing customers, so you don’t have to have bought a Portofino and a GTC4Lusso just to get your name on the list.

STORY Ollie Marriage
The twin turbo 4.0-litre V8 alone develops almost 800hp
Early criticism was levelled at the SF90 because the aluminium chassis and twin turbo V8 mimic the F8 Tributo. In reality very little is shared.
Take the engine. It uses the same basic block, but pretty much everything – turbos, inlet and exhaust manifolds, the entire, radically different cylinder head, crankshaft, pistons – is new. It’s direct injection.
That’s a first for a Ferrari V8. It’s wider bore. It’s 25kg lighter than the F8 engine, and mounted 50mm lower in the chassis, dropping the centre of gravity by 15mm. The exhaust is made from Inconel, like an F1 car.

Alone it develops 780hp and 800Nm. The F8 motor is already the world’s most responsive turbo engine. Imagine what this is going to be like. Ferrari did admit the lessons they’ve learned on this development will be used elsewhere in the future.
It’s Ferrari’s fastest accelerating car ever
The claims are 100km/h in 2.5secs and 200km/h in 6.7secs. The latter figure is 1.5secs ahead of the F8 Tributo, and in the same league as the Koenigsegg One:1 and McLaren Senna.
The top speed is a less remarkable 340km/h. As Bugatti proved with the Veyron, 1000hp can take you higher, but one of the things about the SF90 is that over 210km/h the electric motors that drive the front wheels can spin no faster and are switched off.
From that point on you have to make do with 780hp. Oh, and it’s a second faster around Fiorano than the LaFerrari.
There’s no reverse gear
Not in the conventional sense at least. The gearbox is an 8spd twin clutch that sits behind the engine. It’s 10kg lighter than the 7spd transmission in the F8, and sits 15mm lower.
One of the ways they saved weight was by removing the components that manage reverse gear. That task is now handled by the twin electric motors on the front wheels.
And don’t worry if you’ve drained the electric on your last lap and don’t think you’ll be able to reverse into your pit garage – in such circumstances the V8 fires up to send power to the battery and on from there to the motors.
The brake pedal isn’t connected
The best way to get the electric motors’ regen braking and the regular caliper braking to talk to each other and feel natural, says Ferrari, is to remove the physical connection between the two and let the algorithms have at it.
The same philosophy also dictated a switch to pure electric power steering (a first for a mid-engined Ferrari), and the management of the 4WD system. The key, says Stefano Varisco, the Head of Vehicle Dynamics, is that “you don’t feel the complexity”.
It’s not made from carbonfibre
Perhaps surprising, but Ferrari continues to insist that an aluminium chassis suits their needs best.
The chassis is substantially modified from the F8, and the rear bulkhead between passenger compartment and engine is carbonfibre, which is 25 per cent lighter and has helped boost torsional rigidity by 20 per cent.
We suspect carbon would have been too much of an investment for a series production car at the moment. The day will come, though.
You can make it 100kg lighter
As standard the SF90 has a 1,670kg dry weight. The Assetto Fiorano pack I mentioned earlier saves 30kg from that. If you then tick all the lightweight options, such as the carbon wheels, you can bring the weight down a further 70kg.
And apparently there’s a level of extra personalisation beyond that, where you can elect to have extraneous items such as the door pockets removed. Needless to say, shedding weight from the car also means shedding weight from your wallet.
It’s friendly to drive
According to development driver Raffaele de Simone, it’s an easy car to drive: “It’s less physically demanding than the 488 Pista, more usable, but still has slight oversteer characteristics with the power on”.
Of course it does. That’s because 800 of the 1000 horses are sent to the back axle, Rafa.
Physical dials are gone
The famous centre rev counter is no more. The mechanical dial has been replaced by a 16-inch centre screen. That’s operated by a thumb swipe pad on the steering wheel.
The lower half of the wheel contains a manettino in its traditional position on the right, while on the left a touch-sensitive panel allows you to choose your hybrid mode. There are four to choose from: eDrive, Hybrid, Performance and Qualify.
It has weight saving aero
Yes, you did read that right. Besides delivering a total of 390kg of downforce at 250km/h, the aero team at Maranello managed to develop a rear wing so clever they’re patenting it.
Instead of it being forced up into the airflow, the main body of the rear wing stays static, and a smaller centre section drops down. The motors that do this operation can obviously be much smaller, hence less mass.
There’s no movable aero at the front, but there’s an S-Duct feeding air through the bonnet and vortex generators underneath. Most significantly, the underfloor of the chassis has been stepped to promote downforce – in the footwell your feet are 15mm higher as a result.
It’s the first Ferrari you can plug in
I know, this hardly seems very radical these days, especially since the Porsche 918 Spyder and McLaren P1 both had this functionality way back when. But for Ferrari to make this leap – to make a turbocharged V8 hybrid their flagship rather than a naturally aspirated V12 – is a big step. The first time since the F40, in fact.
But no, you’re not going to be blown away by the e-stats here. With weight a key concern, the battery pack is only 72kg – just 7.9kwh. Still, that’s enough for a range of around 25km and an all-electric top speed of 135km/h.
Together the twin motors on the front axle (they’re tiny, each only weighs 12kg), deliver a combined 220hp. And naturally there’s full torque vectoring to assist cornering ability. There’s an even more enticing end result too: on the WLTP cycle this is a 154g/km Ferrari that returns 6.1l/100km.
