Although there are some details has already been announcedFormula E officially unveiled its Gen3 car today ahead of Monaco’s E-Prix this weekend. Big changes will come in terms of power and efficiency when the new cars hit the track next season, but the cars will also have a new look that is different from the current second generation designs. In fact, Formula E has gone so far as to call the Gen3 “The most efficient racing car in the world.”

So far, the focus of the Gen3 has been on significant performance and efficiency improvements, but the car also features a new overall body design. The wheel covers are gone both front and rear, making the new model more of a true open-wheel machine. There are also no separate fenders over the rear wheels. Instead, the Gen3 has two jet fins on the back. This is because the car’s aerodynamic shape was inspired by fighter jets and indeed the car looks a bit like a more modern F-18 on wheels.

Formula E hopes the new design, which is lighter and smaller than the Gen2 model, will make racing more fun. Like the new F1 cars debuting this season, the Gen3 is built for more speed, but also for more agile wheel-to-wheel racing. Any setting that allows for more duels on the track usually means a better view for the fans. In addition, these cars need to be two to four seconds faster in both qualifying and racing.

“Gen3 is a creature made for its habitat: racing through city streets in wheel-to-wheel battles,” Formula E CEO Jamie Reigl said in a statement. In fact, the show says it’s the world’s first racing car specifically designed and optimized for street racing. With that in mind, it’s only fitting that the series debut the car in Monaco, where last year’s E-Prix there were half a dozen lead changes and over 60 overtakes.

In terms of powertrain, Formula E says the Gen3 car is “the most powerful, lightest and fastest race car to date,” Reigl said. “The Formula E Gen3 race car represents a leap forward for motorsport and electric vehicles,” he explained. “Designed to demonstrate that high performance, efficiency and sustainability can be combined without compromise.”

Internally, the electric motor can deliver 350 kW (470 hp) for a top speed of 200 mph (320 km/h). What’s more, Formula E explains that the Gen3’s power-to-weight ratio is twice that of a comparable internal combustion engine (ICE). For reference, the average speed of Formula One cars is between 220 and 230 mph during a Grand Prix, depending on the circuit layout. Then there is engine efficiency. Formula E says that electric powertrains can convert more than 90 percent of their energy into mechanical energy, compared to about 40 percent for an internal combustion engine.

“The overall performance of the car will be much better than it is today,” Roger Griffiths, team principal for Avalanche Andretti Racing, told Engadget. “This is the exciting part — the combination of lighter weight, electric powertrain and regeneration. Two to four seconds faster on the race track is great.”

The Gen3 won’t rely solely on batteries for power. About 40 percent of the energy the cars will use during the E-Prix will come from regenerative braking. It will also be the first Formula car to feature front and rear powertrains, adding 250kW to 350kW at the rear. All this adds up to 600 kW, which is more than double the regenerative capacity of Gen2. Another first for the Formula car, the Gen3 will no longer feature hydraulic rear brakes thanks to the addition of a front powertrain and its regenerative power.

“As racers, we are always happy to race more competitive cars with more performance and more efficiency,” ROKiT Venturi Racing driver Edoardo Mortara told Engadget. “With this new Gen3 car, it will be lighter, more powerful and with more grip, so it will make [racing] funnier.” Mortara said the second transmission up front could be a challenge, requiring a new driving style and allowing for new racing strategies from the current Gen2 car.

Of course, sustainability is also a key element of Formula E’s overall mission, and Gen3 certainly takes that into account. The series says it will be the first Formula car to incorporate life cycle thinking, or how used components are handled after they are retired. In this case, the recycling of tires, parts and battery cells already has a “second life”.

For Hankook’s new tyres, Formula E says the new process allows 26 percent of the tire to be made from environmentally friendly materials, including natural rubber and recycled fibres. The series plans to use the same process used in the aviation and aerospace industries to recycle carbon fiber to produce a material that can be used for other purposes. In fact, recycled parts from current Gen2 vehicles will be used to make components for new vehicles. Formula E says this is the first time that recycled materials have been used in the back of a Formula car. Finally, the Gen3 will be a zero-carbon car, matching Formula E’s achievement as the first zero-carbon sport. Part of this is stringent sustainability criteria for suppliers.

“Efficiency is everything to me,” Mahindra Racing director Dilbag Gill told Engadget. “If you look at each setting, it becomes more optimized. 40 percent regeneration is so cool and I think that’s something that will apply to road cars in the future and that’s something we’ll learn a lot from.”

While Formula E has done some of its own testing and simulations on the track, the teams have yet to get the new car up and running. The series states that seven teams – DS Automobiles, Jaguar, Mahindra Racing, Maserati, NIO 333, Nissan and Porsche – have signed a contract with the FIA ​​to race a Gen 3 car in Season 9. Pre-season testing should begin this winter.
