In stock form, the rally-inspired Toyota GR Yaris is one of the hottest hatchbacks on the market, but that hasn't stopped aftermarket tuners from tinkering under the hood to extract more power and put established sports cars to shame. Looking at the exterior, you certainly won't mistake this creation for a stock Toyota Yaris.

What you're looking at is the work of aftermarket tuner HKS, which has fitted an aggressive Rocket Bunny widebody kit that adds flared wheel arches to the front and back, along with a massive rear wing that generates more downforce. A colorful HKS racing livery also helps it stand out. The standard car doesn't look tame, but this modified version is on another level.

Transferring all that power to the tarmac is a set of forged aluminum Advan Racing R6 wheels wrapped in Yokohama Advan A052 tires to improve the hatchback's track performance.

The modifications continue under the hood, where the tuner has tweaked the ECU and added a larger turbocharger and a new intercooler with an integrated spray system, boosting the output to 375 hp. Adding a 100-shot of nitrous raised the output to 475 hp - that's a massive increase over the stock car, which generates up to 268 hp and 272 lb-ft of torque from a turbocharged 1.6-liter engine.

A custom coilover suspension lowers the height and stiffens the ride for improved handling when the car is pushed to the limit. To see what the tuned GR Yaris can do, the hot hatch was taken to the Tsukuba Circuit for some timed laps.

In its fastest lap, it raced around the Japanese circuit in just 58.4 seconds. To put this into context, that's faster than the 2020 Nissan GT-R Nismo, which holds the current production lap record at Tsukuba with a time of 59.3 seconds. Now if only the Toyota GR Yaris could come to America because we would love to get behind the wheel of what is proving to be one of most exciting cars of the last few years.
