Porsche 718 Boxster Spyder To Get GT3’s Flat-Six

Sticking to its promise of creating more enthusiast-focused vehicles, Porsche Motorsport is said to be developing a new 718 Boxster with the naturally-aspirated flat-six engine of the 911 GT3.

Autocar reports that the next-generation Boxster Spyder will be heavily related to the new Cayman GT4 and ditch the car’s existing turbocharged 2.5-liter flat-four. Keen to give Porsche enthusiasts what they’ve been begging for, the motorsport-related six-cylinder of the GT3 promises to transform Porsche’s entry-level model.

Fittingly, it seems inevitable that power from the flat-six, rated at 493 hp in the GT3, will be slightly reduced for use in the Boxster Spyder, perhaps nearer the 425-450 hp mark. Mated to the engine will be a six-speed manual transmission but a dual-clutch, seven-speed PDK will also be offered to customers looking for slightly more convenience.

Beyond its new powertrain, Porsche will look to strip out any unnecessary weight and potentially ditch the likes of air conditioning, radio and sound insulation. Michelin Pilot Sport Cup 2 tires are expected to come standard and like previous iterations of the Boxster Spyder, the folding soft top will be replaced by a manually removable fabric top.

A debut in 2018 seems likely.

    That’s great. Actually may consider over a 911…

    *may*

      Great, yes indeed, by it self…, but this over the 911, no!

    • SteersUright

      I’d have to agree. The Spyder in particular, with the top down to take in that glorious engine noise, would be my choice despite the slight rigidity benefit of the coupe (Cayman).

    why not same engine from GT 4?

    • Vassilis

      The current one? Because it isn’t as special as the GT3’s.

  • Vassilis

    So the new GT4 will have the same engine? Awesome!

      718 Cayman GT4 with GT3 engine and 9000rpm… PDK or manual, I’d take either. Would give Evora GT430 a run for its money.

    Man… if this thing has like 450 hp it’s going to be crazy. I just don’t think that I could bring myself to pay $100,000 for a Boxster though. I’d do it for a 911, but not a Boxster. Especially since I don’t track my car but a few times a year. I would definitely pick this car over the 911 for track days and mountain carving, but the other 95% of the time I’m in the city or on the road between cities where I’d prefer the additional space and creature comforts of the 911.

      When a 911 with this engine transacts at around $180k new and you can have all of the performance (perhaps even more so), stunning looks, and save $80k, I think I can easily make the case for buying one of these. Now, to try and remember where I hid that briefcase with my spare $100k…

      Also, the GT3 is not a “creature-comfort” car by any means, so you’d be better served by any other 911 below it which are all amazing cars. For me? Boxster Spyder all day!!

    These next two Porsche GT versions of the Cayman and Boxster will be the most desirable ever and likely spur another 991 R speculator-flipping scene. These will be hugely collectible so I truly hope Porsche makes them in massive numbers so that those who want to drive the shit out of their, CAN(!!!) and wont have to worry about it being 1 of 750 sold worldwide or some nonsense.
