Lessons learned on the Grand Prix track can bring Bosch’s hybrid racing generation to road cars

Following a trail through a paddock carved out in the area between the Detroit River and the iconic gas-powered machines at the Renaissance Center in Motor City, head to the city track for this weekend’s Detroit Grand Prix races.

However, those fast and sublime brutes are not all the same. A bright blue car sports a sticker on its fender that reveals it’s not just liquid fuel that will strain its high-performance engines.

This label only has 3 words: “Bosch electrified hybrid”. This means that the race car is a LeMans Daytona hybrid vehicle powered by a standardized hybrid-electric formula developed by German automotive generation company Bosch in collaboration with the International Motor Sports Association, or IMSA.

Through this partnership, LMDh cars are the first North American hybrids eligible to compete in Grand Touring Prototype, or GTP, elegance races.

On that day, amidst the hustle and bustle of pre-Award practice laps and other preparations, the IMSA leader and Bosch engineers explained the technical attributes of Bosch’s hybrid formula in the context of the existing event, but the fact remains that the car manufacturers who are fighting for a spot will be able to meet the needs of the Bosch Hybrid Formula in the context of the existing event. In the winner’s circle, I ended up winning sales in the showrooms.

“It’s a laboratory for me. You know the things we’ve learned here, rarely through failures. But when things go bad on the circuit, especially in the race format, it’s like what did we learn here today to make it better. “for the circuit, but think about the customer’s next products. That’s why we do this and I think that’s why OEMs do it,” said John Doonan, president of IMSA at a press conference about Bosch’s hybrid technology.

Transferring the wisdom gained on the track to city cars is a long-standing practice, whether it’s tires, engines, fuels, or technology.

In the case of Bosch’s hybrid formula found in existing LMDh vehicles, it is possible that a number of features will be incorporated into conventional vehicles that increase power, reduce weight and functionality.

“Actually, what we’re doing on the track is accelerating how this generation will look on the road,” explained Jacob Bergenske, Head of Bosch Motorsport. “We have a very mild hybrid, which means we have a small, very compact battery. But to have that much power, you essentially have to be able to charge it by charging it very, very, very fast, and the generation to do that is absolutely at the forefront of the generation on the circuits right now. This is also what greatly contributes to the effectiveness of this system.

The advances in hybrid powertrain generation that Bosch and IMSA are comparing come at a time when consumers who aren’t interested or in a position to ditch their internal combustion engine cars for electric cars seem open to the kind of mid-floor that hybrids can offer. offer.

In KPMG’s American Outlook Survey, only one in five consumers said they would prefer an electric vehicle, compared to 43% who said they would buy a hybrid vehicle for the same load and functionality. Conventional internal combustion cars were the most sensible choice at 38%.

Indeed, while some industry observers see hybrids as a stepping stone for buyers before embarking on an exclusively battery-powered vehicle, Bosch’s director of powertrains believes that advances in hybrid generation may satisfy some consumers’ preference for a sustainable vehicle.

“Basically, the NOx, smog and pollutants that we have can also be reduced by hybrid technology,” Fatouraie said. “Simply put, it optimizes the operation of the engine and eliminates the gaps where the engine might have contaminants in the pipes, because you now have a very solid formula that can increase the torque and force needs that you want so that you can necessarily run your engine at an optimal point.

Improving power also involves reducing the length and weight of batteries and silicon carbide chips, which Bosch plans to start generating in the U. S. The U. S. government is open to the U. S. through 2026, Fatouraie said.

In terms of electric power capability, Bosch’s hybrid formula will be an attractive feature of some battery-electric pickup trucks.

“Now you have in your vehicle the plant that can be your home,” Fatouraie said.

However, he notes that for certain uses, such as commuting or shopping, electric cars are an option. In fact, Fatouraie says he has one.

This weekend, LMDh cars known as the “Bosch Electrified Hybrid” label will compete for Grand Prix victory on the streets of downtown Detroit, with the longer-term purpose of building on what they learned on the track to produce higher-performance hybrids to win in the showroom.
