The Spirra is almost here. South Korea is about to introduce its first supercar, nine years after the Proto Motors PS-II prototype was first revealed to the press. After navigating through rough seas, including being bought out by a company called the Oullim Group, Proto Motors (now Oullim Motors) is confident of a 2010 summer market introduction.
Maximum power will come from a 2.7 liter V6 Hyundai sourced motor with four different outputs. At its meekest, it will produce 129kW (173 bhp/ 175 PS) and torque of 245 Nm (181 lb-ft) at 6,000rpm. The second configuration features a small turbo that helps it push 243 kW (325 bhp / 330 PS) and 471 Nm (347 lb-ft). At the third-highest level is a power output of between 294 kW (395 bhp/ 400 PS) and 309 kW (414 bhp/ 420 PS), assisted by a bigger turbo. Peak torque for this engine is 490 Nm (361 lb-ft).
The most powerful of them all is persuaded by two turbos encouraging between 331 kW (444 bhp/ 450 PS) and 368kW (493 bhp/ 500 PS). The maximum torque is 539 Nm (398 lb-ft). Drive is through the rear wheels via a 6-speed manual gearbox. At its quickest it goes from 0 - 100 km/h in 3.5 seconds. Top speeds range from 212 km/h to 310 km/h.
Road grip is provided by 225/40R 19 front and 275/40R 19 rear tyres. The Spirra has a mid-engine layout and is constructed by hand.
The body is made from carbon fibre, enclosing a tubular spaceframe. It is all lightweight but very stiff at the same time. The Korean auto industry does not yet have a well-developed supercar heritage and as such, these manufacturing technologies are not common for the general market.
