Porsche 919 Hybrid Evo Explained – Video
Porsche works driver Neel Jani lapped the 7.004 kilometre long Belgian Grand Prix Circuit in the Ardennes mountains in 1:41.770 minutes. The 34 year old Swiss has beaten the previous record by 0.783 seconds that was set by Lewis Hamilton (GB) at the wheel of a Mercedes F1 W07 Hybrid. Hamilton’s lap of 1:42.553 minutes dates back to August 26 in 2017 and secured him pole position for last year’s F1 race. Jani achieved a top speed of 359 km/h and an average speed of 245.61 km/h on his record lap that he started at 10:23 hrs. Ambient temperature was 11° Celsius, track temperature was 13° Celsius.
Fritz Enzinger, Vice President LMP1: “This was an absolute fantastic lap – an outstanding drivers’ performance from Neel and the result of great engineering. Today’s track record impressively proves the ultimate performance of the most innovative race car of its time. Our target was to show what the Porsche 919 Hybrid is able to do when we loosen the restrictions that normally come from the regulations.”
Team Principal Andreas Seidl: “This additional success is the result of the LMP team’s hard work and a proud day for the engineers. One can only congratulate Neel and the entire crew for achieving it. All six 2017 LMP1 drivers contributed to the project. It was our target to show the Porsche 919 Hybrid’s abilities when we ease the restrictions that came from the World Endurance Championship regulations.”
With the 919 Hybrid, Porsche has won the Le Mans 24-Hours from 2015 to 2017 three times in a row as well as the world champion titles for both, manufacturers and drivers, in the FIA World Endurance Championship (WEC) during the same years.
Neel Jani: “The 919 Evo is brutally impressive. 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. The speed on which everything happens on a single lap with the 919 Evo is that fast that the demand on reaction speed is very different to what I was used to in the WEC. We are not only faster than the F1 pole from 2017. Today’s lap was twelve seconds faster compared to our WEC pole position from last year! We have had three very intense days at Spa. Today I knew on the very first lap in the morning that the car’s performance was super. The race engineers did a great job setting up the car and the Michelin tyres are sensational. A big thank you to Porsche for this experience.”
Unchained for the record
The technical regulations from the FIA for the WEC and Le Mans successfully delivered close competition between the conceptually very different class 1 Le Mans hybrid prototypes entered by Audi, Porsche and Toyota. As a consequence this never allowed the question – what would be the potential of the Porsche 919 Hybrid if it wasn’t chained by the limitations – to be answered; until now.
Stephen Mitas, Chief Race Engineer LMP1, was heading the project: “It was kind of an engineer’s dream come true for us”, the Australian admits. “Having developed, improved and raced the car for four years, the guys had a very close relationship to it. We all knew, no matter how successful the 919 Hybrid was, it could never show its full abilities. Actually even the Evo version doesn’t fully exploit the technical potential. This time we were not limited by regulations but resources. It is a very satisfying feeling that what we’ve done to the car was enough to crack the Formula One record.”
To prepare the record car, the base was the 2017 world championship car. On top came developments that were prepared for the 2018 WEC but never raced after the end of 2017 withdrawal. Additionally, several aerodynamic modifications were made.
For the ‘Porsche 919 Hybrid Evo’ the entire hardware of the power train remained untouched. The 919 is powered by a compact two-litre turbo charged V4-cylinder engine and two different energy recovery systems – brake energy from the front axle combined with exhaust energy. The combustion engine drives the rear axle while the electro motor boosts the front axle to accelerate the car with four-wheel drive. At the same time it recuperates energy from the exhaust system that otherwise would pass unused in to the atmosphere. The electrical energy that comes from the front brakes and the exhaust system is temporarily stored in a liquid-cooled lithium ion battery.
