Remember the Toyota GR Super Sport? Toyota presented the it as a concept back in 2018 previewing a new hypercar that will take on the Aston Martin Valkyrie, Mercedes-AMG One, and Koenigsegg Jesko. It was going to be a road-going version of the GR010 Hybrid currently racing in the 2021 FIA World Endurance Championship.

After the concept was revealed, Toyota presented a prototype of the GR Super Sport at Le Mans. Unfortunately, it looks like plans to develop a road-going version of the GR010 Hybrid have already been scrapped before the project got off the ground.

According to Japanese media via Racer magazine, a pre-production prototype of Toyota's Valkyrie rival was involved in a "serious incident" earlier this month while being tested at Fuji Speedway. The pre-production prototype reportedly caught on fire, causing serious damage to the car.

This has reportedly caused Toyota to have second thoughts about developing a road version of the GR010 Hybrid. While it sounds like Toyota's road-going hypercar has been canceled, the incident does not affect Toyota's racing program for the GR010 Hybrid. Unlike the Valkyrie, the GR010 was built to meet technical regulations for a prototype-based hypercar. These regulations do not require manufacturers to make an equivalent road car.

It seems silly to cancel a production car because of one development accident, but perhaps Toyota is looking to avoid future issues and law suits arising from selling a vehicle that is tough to handle. After all, it wouldn't want to face similar suits to what Porsche endured after Paul Walker met his demise in a Carrera GT.

It will be a shame if Toyota abandoned plans to make a production version of the GR010 Hybrid as it would be nice to see Toyota with a halo in its road car lineup besides the Lexus LC. Whereas the GR010 generates 671 hp from a 3.5-liter twin-turbocharged V6 and a motor-generator unit, the GR Super Sport road car was going to be powered by a 2.4-liter twin-turbo V6 and three electric motors.

Combined, this setup would have reportedly produced around 1,400 horsepower. Each example was expected to cost around $3 million.
