Porsche 919 Evo specs


The 2019 919 Evo runs on a 2.0L V4 turbo hybrid engine that puts out 900 ps.

That’s stored in a liquid-cooled lithium ion battery, and then used to drive an electric motor on the front axle while the engine drives the rear, for maximum all-wheel-drive acceleration. The Porsche 919 Hybrid Evo's time breaking design set a new lap record at the Spa Francorchamps racing circuit. It could easily be developed to survive an endurance race at this output level, Mitas says.The Evo uses an all-new brake-by-wire system, allowing adjustable brake-based torque vectoring and yaw control.The Evo recuperates roughly 30 percent more energy than what's mandated during WEC competition, which leads to higher speeds on straights and more forceful braking. So the Evo uses fixed-height skirts, though they are larger than what the Le Mans racer wore.To contend with the Evo's higher loads during cornering, "we added a second power-steering pump in tandem to the original module, which increased assistance by 40 percent," explains Mitas.Michelins with a softened compound and less durability provide significantly more grip for the Evo. "However, we are currently unable to test this hypothesis. If it is not then what is the reason for poor math skills and notes about "nitro" results instead of "regular ones".The 919 Hybrid Evo (the ultimate version of the 919 Hybrid) just set a new world-record on Spa - faster than all the F1-cars. Adjustable elements make for less drag on straights.Redline stays put, but the engine makes more torque across the operating range. Even in low downforce mode, these cars can brake 4+Gs.

Our car experts choose every product we feature. They are the same size that the 919 used in WEC competition but run at higher pressures to contend with the Evo's increased downforce.

Porsche's engineers cut the 919 Evo's weight by dumping useless frills like the windshield wipers, lights, air conditioner, electronic race controls, and the pneumatic jack. Without imposed limits, that motor now adds another 440 horsepower (as much as the total power of a BMW M3), up 10 percent.This record setting lap is part of a farewell tour for the Le Mans winning car. The Evo exaggerates the 919 Hybrid, but only to a point. “It is definitely the fastest car I ever drove, the grip level is at a fully new dimension for me, I couldn’t imagine this amount beforehand.”Turns out, when you get to ignore the rules that govern the World Endurance Championship (which includes Le Mans), there's a lot you can do to go faster. They upgraded the suspension and tires to deal with the extra loads.The Evo carries the same two-liter, turbocharged V4 engine as the Le Mans-winning car, minus the fuel flow meter that limits how much gasoline goes kaboom. They are the same size that the 919 used in WEC competition but run at higher pressures to contend with the Evo's increased downforce.

Porsche gives its Le Mans program a blistering send-off.Quick at Germany's legendary 12.9-mile, 73-turn Nürburgring Nordschleife is The Evo was born as a tribute to Porsche's three-time Le Mans–winning 919 Hybrid after Porsche quit the World Endurance Championship's LMP1 class at the end of the 2017 season to focus on developing a car for the Formula E series. So when Porsche gave its people the chance to break free and show what their machines can do, they overdelivered.

In 2017, the 919 Hybrid was limited to 0.65 gallon of fuel for every 4.35-mile lap of Spa. In Evo form, it slurped 1.03 gallons per lap at that track, a 58 percent increase. "An autonomous 919 should be able to match the lap time of the perfect human driver, as the performance limit would then be the vehicle," Mitas says.
