One of them is called the 718 Cayman GTS 4.0 and has the engine in the center of the vehicle’s architecture. The series itself marks the entry into the world of sports cars from Zuffenhausen. The GTS 4.0 is again the top model of the 718 cars. What does the mid-engine fun cost you in everyday life? Find out here.

Our test consumption

It’s not often that the standard consumption in the WLTP cycle (here: 10.9 liters of Super Plus per 100 kilometers) is higher than our test consumption. But the 718 Cayman GTS 4.0 completed our lap with an average thirst of 10.5 liters. This puts the fuel costs at 14.58 euros over a distance of 100 kilometers. The gentle Eco lap lowers consumption to 7.6 liters, while 10.5 liters shoot through the pipe again on the commuter route. If the top Cayman is driven as it should, consumption rises to 13.6 liters of Super Plus. The fuel costs are calculated on the basis of the current fuel price on our partner portal (29.12.2020 / Super Plus: 1.389 euros/liter).

The test consumption is made up of 70% commuter round and 15% each Eco and Sport.

Monthly maintenance costs

The economy mode therefore costs 10.56 euros at the pump after 100 kilometers. By contrast, those who drive the same distance in a decidedly sporty manner pay 18.89 euros. The annual vehicle tax is 384 euros. Third-party liability insurance is available for 343 euros per year, while partial and fully comprehensive insurance cost an additional 194 and 1,272 euros respectively. If you drive 15,000 kilometers a year, you can expect monthly operating costs of 413 euros. If you drive the sports car 30,000 kilometers over the asphalt, you pay 749 euros. We leave the depreciation out of this calculation.

The Porsche 718 Cayman GTS 4.0 costs at least 80,703 euros.

How it’s tested

The auto motor und sport test consumption is made up of three differently weighted consumption journeys. The so-called “commuter consumption” accounts for 70 percent. This involves a journey from home to work that measures an average of 21 kilometers. A particularly fuel-efficient 275-kilometer eco-trip accounts for 15 percent of the total. The remaining 15 percent is accounted for by the sport driving lap. The length is roughly the same as the eco lap, but the route includes a larger proportion of freeway and therefore higher speeds on average. The basis for calculating fuel costs is always the price quoted by the “mehr Tanken” portal on the day the article was written.

The monthly maintenance costs include maintenance, costs for wearing parts and vehicle taxes for an assumed annual mileage of 15,000 and 30,000 kilometers without depreciation. The calculation is based on test consumption, a three-year holding period, no-claims class SF12 for third-party and fully comprehensive insurance with Allianz including discounts for garage parkers and the restriction to certain drivers (not under 21). SF12 means a discount rate of 34 percent for liability and 28 percent for comprehensive insurance at Allianz.
