Porsche 718 Boxster GTS spied with up to 375bhp
Exterior upgrades and performance tweaks will make the new Cayman and Boxster GTS models the hottest in the current range
The Boxster GTS was spotted testing completely undisguised on the Nürburgring, revealing its altered front bumper treatment and twin central exhausts, suggesting the fitment of an upgraded exhaust system for an improved engine note and performance boost.
The previous-generation GTS models gained 15bhp and 7lb ft over their standard S counterparts, so it’s likely that there will be a notable power hike on this generation’s flagship, too. An output of about 375bhp is expected, but it isn’t expected to go any higher to avoid treading on the toes of the entry-level Porsche 911, .
The GTS will use the same turbocharged 2.5-litre flat four engine as the 718 Boxster S. Porsche hasn’t yet confirmed how the higher output will be achieved.
As well as the power boost, the GTS will benefit from suspension upgrades; the previous-generation GTS featured Porsche’s electronically controlled adaptive dampers, as well as slightly lowered suspension. Porsche’s Active Suspension Management is likely to feature, as is the Sport Chrono package; this featured on the previous Boxster GTS.
The 718 Boxster S costs £54,569, so the GTS version could easily pass the £65,000 mark. Performance could also match the 4.2sec 0-62mph time of the previous-generation Cayman GT4.
Expect the new Boxster and Cayman GTSs to break cover at the Frankfurt motor show in September, before order books open at the end of the year. First deliveries aren’t likely to take place until early 2018, though.
