Porsche has dropped its 2.5-litre, four-cylinder turbocharged 718 Boxster and Cayman GTS models from its portfolio, replacing them with new variants powered by the 4-litre, naturally aspirated flat-six engine from the Spyder and GT4.

These two new models sit above the 2.5-litre, four-cylinder turbocharged S variants and below the aforementioned Motorsport Department cars, and will go one sale later this spring, with the Cayman GTS costing from £64,088 and the Boxster equivalent an additional £1861.

> New 2019 Porsche Cayman GT4 review - it's a bit special

Besides a tweak to the ECU reducing the four-litre’s output by 20bhp (the GTS models produce 394bhp), the flat-six engine is carried over wholesale from its more exotic family members, as is the sports exhaust system. While torque and weight figures haven’t been quoted – expect in the region of 295lb ft and 1420kg – Porsche has confirmed the performance figures: 0-62mph in 4.5sec and a 182mph maximum for the pair. And currently, only a six-speed manual transmission is offered.
