In recent months, a selection of aggressive Porsche Cayman GT4 prototype have been spied testing. The car is expected to be the most track-focused and fastest variant of the Cayman and now a potential Porsche Boxster GT4 prototype has been spied during winter testing.
Like Cayman GT4 test mules, this Boxster features the same front end incorporating a more prominent splitter as well as enlarged air intakes. Additionally, the car is fitted with beefed up wheels and tyres, upgraded drilled brake discs and bright red brake calipers.
Furthermore, the Porsche Boxster GT4 features a prominent bootlid lip spoiler and certainly looks like the most potent Boxster derivative ever.
If this is indeed the Porsche Boxster GT4, then it will feature the same mechanicals as the Cayman GT4. That means the company’s 3.8-litre twin-turbocharged boxer six engine is likely with power potentially sitting at the 450 hp range.
