The hot Hyundai i30N - a rival to the Volkswagen Golf GTI and Ford Focus ST, will be revealed at 1pm today, alongside the i30's Fastback variant.
Hyundai previewed its upcoming i30N in a new video of the hot hatch at the Nürburgring - released before the car is revealed on 13 July.
In the footage, the brand's head of vehicle testing and high performance development, Albert Biermann, says the car has been developed to withstand long stints at track pace.
Along with its road car testing, the brand entered two racing i30Ns into this year's Nürburgring 24 Hour event - something it said has helped improve the road car.
"We have everything available," he said. "It's too early now [for hybrid powertrains in N cars], but the time will come soon, definitely."
The car's engine produced 259bhp and 227lb ft at 6000rpm, suggesting the final road car could offer similar performance.
Hyundai has been working on the development of performance models since 2013, when it first launched the ‘N’ brand as part of its World Rally Championship assault. The company has a 3600m2 test facility at the Nürburgring.
