Porsche has whipped the covers off its new Boxster 25 Years, a 294 kW limited-edition model conceived to celebrate – you guessed it – a quarter of a century of the roadster nameplate.

Yes, the first Boxster was launched back in 1996, with more than 357 000 units having since been produced.

Just 1 250 examples of the new Boxster 25 Years will be built. The special model is based on the 718 Boxster GTS 4.0 and is thus powered by a naturally aspirated 4,0-litre flat-six engine with 294 kW and 420 N.m. The newcomer will be offered with the choice of a six-speed manual gearbox or a seven-speed dual-clutch transmission. Fitted with the aforementioned PDK transmission, the special-edition model will sprint from standstill to 100 km/h in a claimed 4,0 seconds, before topping out at 293 km/h.

So, what sets the newcomer apart from the standard Boxster GTS 4.0 on which it is based? Well, the Zuffenhausen-based firm says it has added a number of references to design features of the Boxster concept car that previewed the original open-top two-seater at the 1993 Detroit Motor Show.

The special model gains elements – such as the front apron, side air intakes, model lettering and two-tone 20-inch alloy wheels – in that concept's “reinterpreted” Neodyme hue, which it describes as a “copper-like shimmering brown”.

The Boxster 25 Years will be offered in GT Silver Metallic, Deep Black Metallic or Carrara White Metallic. The fuel-filler cap, meanwhile, gains the Porsche script from the Exclusive Design range in an aluminium look. The high-gloss tailpipes of the sports exhaust system echo this finish, while the windscreen surround comes in black.

In another nod to the 1993 concept, the special model combines a Bordeaux leather interior with a red fabric convertible top (also available in black). The convertible top bears embossed “Boxster 25” lettering, while an interior aluminium package, 14-way electrically adjustable sports seats, “Boxster 25" door sill trims and a heated GT sports steering wheel all ship standard.

Other standard features of the Boxster 25 Years include Porsche active suspension management sports suspension (with a 10 mm ride height drop) and torque vectoring with a mechanical limited-slip differential.
