Porsche GT4 ePerformance | Car engine and sports

Diving, why not? Because of the spring weather in the Valencia region? There is little time left at the start and straight end of the Riccardo Tormo circuit, which the Porsche GT4e Performance has already evaporated to a large extent with a wild howl at a power level of 450 kW, so quickly plunged into the mothball of motorsports. BMW M1 Procar series, what was that again? Formula 1 drivers who, before their actual race, ride identical race cars to prove their qualities as entertainers at the wheel to viewers – not a bad idea.


It’s also likely the Porsche motorsport team, which doesn’t really know what to do with its concept of an electric-powered GT race car. It’s housed in the enlarged chassis of the 718 Cayman GT4 Clubsport, whose nose is now sinking toward the curve. No, don’t let the upper left handle on the steering wheel bother you. Even if the setup options for ABS are wrong – ePerformance has none. The steering wheel comes from the 911 RSR. On the other hand, the lower right handle works, three clicks, and the competition mode is active.


1.6 tons of pure sport

So please now boldly brake the 1.6t Porsche, but with enough sense that the lights on the left and right above the instrument cluster don’t light up purple. If so: fixed wheels, followed by smoke and perhaps a Michelin angle. hideous. The pit crew told me before the start it would light up before I noticed the wheels were locked, so I released the brakes immediately. Now the boys sit in front of six screens and see every mistake I make on the steering wheel and pedals in real time. But now nothing lights up. Take a lot of speed, a little over 140 km/h, then go back to the throttle, a slight increase, the GT4 ignores it and accelerates relentlessly.

700 kW can leave marks.

Turn a second, brake again, now it’s purple, it’s already smoking, release the brakes a little, hey, you’re driving a meter and a half away from the perfect line. The danger of electric racing cars: Estimating speed and conditioning braking points. why? The voice guidance that your internal combustion engine assembly released is missing. It doesn’t even have to be the traditional shifting and clinging that featured Procar warriors.


On the road?

No, even the automatic transmission in modern touring cars gives the appropriate feedback, backed by the fact that the driver initiates the shifting process by tugging on the steering wheel pedals. None of it there. It seemed, yes, it is. Intense buzzing and howling, not artificial, but real, OK even, but linear with speed. And the speed is always there. Immediately. Also because: grip. Four-wheel drive due to the two motors, ultra-fast and precise power distribution for fat spots. So, pick up a bit before the next left turn, then at full speed for a moment, come back to the brakes, and take off on the tight right turn.


Of course, the GT4 doesn’t feel light here, but it drives frustratingly agile, slams its way into turns, looks steady, is stable, and clearly tells you: Now get back on the right pedal! No matter what! and how to do it. To make it work: two motors and an 82 kWh battery (net: 65 kWh). Although the “single” battery is not entirely correct, because it does not fit into the position where the combustion engine was before: in the middle of the car.

Michelin is preparing special tires for the project, which are said to be particularly sustainable.

So 25 percent of every lawn is under a huge carbon hood at the passenger’s feet and under the front hood. By the way: There is another prototype that works without the smaller batteries. It weighs about 250 kg less. It looks more lively in the corners, but runs only 210 km / h on the strait, otherwise the power will be wasted very quickly. But that’s just by the way.


Now: the ninth mode

Whether it is a brand new battery? No, rather NMC 622 VDA 52 Ah cells. Special Feature: Oil Cooling. Compared to Porsche’s flagship Taycan, it reduces thermal resistance from 1.8 W/K to less than 0.2 W/K. This increases the power density from 1,257 to 1,707 W/kg – with a nearly identical power density from 216 to 217 W/kg. Pregnancy? With up to 350 kW.


In any case, the cell not only withstands about 35 ° C compared to the production car, it withstands twice that. It doesn’t have to last that long either. Well, the GT4 ePerformance should hold up. The grand finale is yet to come, you know, and you’re zipping around in a Porsche across the field. Shift to 13, that is, just before the beginning of the end. The eternal left that is slowly closing. Finding the optimal braking point right here would be like winning the Spanish Christmas lottery.

Timo Bernhard (right) gives final advice for a safe trip.

Now in the box, quick check. “Now: Mode 9,” is the command over the radio. Means: Six additional clicks on the lower right rotary switch in the middle of the steering wheel. The ninth mode unleashes 700 kW. Why not the 800, which is still mentioned in Mission R? He also went. With plug from the rear axle.


value-added fire

However, their extra weight can’t make up for the extra performance, but it will put a lot of pressure on the battery. So: 700 kW. Or in D-Mark: 952. That’s too much, I’m sure already at that moment when the Porsche gets out of the pit lane at 60 km/h limited by the pit selector. The weather is heating up. I get fresh air in front of my helmet from two snorkels on the right and left of the dashboard.


In general, you can sit here very comfortably, adjustable chassis, adjustable steering column, enough space under the roof for large helmets. Stop, don’t go on. 700 kW. The Procar guys were already occupied at about half the power. Fine. Eyes closed and go for it. Nowadays. open your eyes! open your eyes. High towards Turn 2, over 200 km/h, hell is another one. Brakes, no purple lights please. Everything fits. to give in. Down, leaned left, lob, of course. Every step on the accelerator: Jericho. Without a fuss. Just force. Feeling as if the bucket seat was about to push through you as you rammed your rear onto the asphalt while the Porsche continued accelerating without moving. Is the Curva de la Afición (as it seems!) still full, as it did previously with 450 kW? Probably. But I can’t imagine that.

Lots of buttons, but nothing to reset the driver’s senses.

But who knows, because until now I did not imagine that this aircraft would also be interesting with 700 kW. Fear eats the soul and so on. But it fits, at least to the extent that you want to get used to the pace. Then. The GT4 holds its own, then overwhelms when expected, for example when accelerating too fast, secured slightly by the front wheels driven. If you get into a tight corner too quickly with too large a steering angle, the front wheels will roll. The same is true when there is a lot of gas … and electricity … and smoke and a very large steering angle. Poor performance, so to speak – in short: with a very high level of amateurism. Then at Turn 14, the Porsche lets out a rumble over the rails at the start – the finish, soon after the start of the new lap, rips it off in the limiter at two hundred and sixty. Braking, picking up the momentum, come on, dare, there’s still something going on. It actually works, just not for long. The 700 kW level is a qualifying mode, for a 30-minute race, 450 kW should be enough. For now.


Porsche is being careful anyway and doesn’t want to carry a one-man-made trophy until 2026 at the earliest. In what framework? Be silent. Assumption: Formula 1. By the way, the Procar era lasted only two years. Ferrari and Renault did not allow their drivers to play, after all they made road sports cars themselves. Maybe not such a good example after all. So: get out of the mothballs in motorsports. It’s time for something new.


opinion poll

No, the carbon dioxide savings are not so high that it is useful to accept the disadvantages in practice.

Yes, e-cars need less power, emit less carbon dioxide overall, and the issue of range is irrelevant due to the increasing power densities and charging speeds of the batteries.

Conclusion

Politicians demand electric mobility for all. Did she also mean motorsport? Did not matter. In any case, racing cars like the GT4 ePerformance can be a lot of fun, especially because of the insane performance. And for all the traditionalists: motorsport is like road traffic – it will still be some time before electronic technology replaces combustion engines. Longing.
