Ferrari SF90 Stradale (1000 HP) brings new tech to hypercar heights
Posted On May 29, 2019
This is the Ferrari SF90 Stradale, a 986-horsepower, all-wheel-drive, plug-in hybrid rocketship that will sprint from 0 to 62 miles per hour in just 2.5 seconds. Or, for those who prefer a stealthy departure, the Stradale can travel up to 25 kilometers (about 16 miles) on electricity alone, thanks to its 7.9-kilowatt-hour, lithium-ion battery pack.
Ferrari’s powertrain guys may have started with the F154 twin-turbo V8, but the changes are such that technical director Michael Leiters describes it as a ‘totally new architecture, with only minor parts carried over’.
Its capacity has been increased from 3902cc to 3990cc, due to a larger bore of 88mm. Intake and exhaust have been completely redesigned, and the cylinder head is narrower with an all-new central injector running 350bar. Internal fluid dynamics have all been optimised, the turbo assembly is lower, and while the exhaust sits higher – and exits above the rear bumper – the whole engine sits 50mm lower in the chassis for a reduced centre of gravity. There’s a much smaller diameter flywheel, and the exhaust manifold is made of Inconel rather than steel.
A high performance, 7.9kWh lithium ion battery sends power to the three electric motors, and even with the ICE switched off the SF90 can still hit 84mph. Ferrari’s control logic manages the power flows according to whether the driver is feeling holy or hedonistic, and splits it across four different driving modes, controlled by the steering wheel mounted eManettin
Ferrari’s latest hypercar was unveiled in Maranello, Italy, on Wednesday, and after having some time to look at and sit in it, I can tell you it’s a stunning thing. But, as ever, there’s a lot more to it than that.
