2018 Porsche 718 Cayman vs. 2018 Chevrolet Corvette

The 2018 Porsche 718 Cayman offers top of the line acceleration, handling and overall performance. Its interior is also comfortable with lots of safety features and amenities. However, the 2018 Chevrolet Corvette is a fierce rival, with the looks and performance to make it a true contender. Which of the two should you buy?

Design & Style

The Porsche 718 Cayman has a sleek, aerodynamic exterior which makes it clear it was built for speed. The side profile has a slight rectangular signature with an outer edge that curves in just the right places. It pays homage to previous Porsche models without adhering to them excessively. The Chevrolet Corvette is a real beauty, with sharp lights in the front punctuated by a sophisticated grill and lines etched into its side. The two cars are tied when it comes to appearance, as both are real head turners.

Technology & Safety

The Porsche Cayman has a fuel economy of 21 mpg versus 16 mpg for the Corvette. Both hold the same number of passengers, which is a maximum of two, and both have done well on crash and safety tests. A four-wheel anti-brake system comes standard in both, but the Corvette has a bit more capacity in its fuel tank, at 18.5 gallons versus 14.3 for the Porsche Cayman. The Porsche is lighter however, at 2,943 pounds versus 3,298 pounds for the Corvette.


These two sports cars differ considerably when it comes to the type of engine they employ.  For instance, the Porsche Cayman uses a Premium Unleaded Intercooled Turbo H-4 engine, while the Chevrolet Corvette opts for a V8. In terms of horsepower, the Corvette stands out with a massive 455 horsepower at 6000 rpm versus only 300 horsepower at 6500 rpm for the Porsche. Each car utilizes the same steering system which is rack pinion, with their front and back wheels being made from aluminum.

The Bottom Line

The Porsche Cayman and Chevrolet Corvette are well matched in a number of areas, with the exception of engine power, where the Corvette really distinguishes itself. Its V8 gives it’s a substantial edge; however this means it is overly thirsty when it comes to fuel, and some have criticized Chevrolet for not offering a V6 turbo variant. Furthermore, the body vents can be distracting, and due to traffic laws and speed limits, few drivers will be able to legally take advantage of the true speed and power it offers. Therefore, the Porsche 718 Cayman wins, due to its greater balance of comfort and performance.
