2018 Porsche 718 Cayman vs. 2018 Alfa Romeo 4C

Automobile enthusiasts have praised both the 2018 Alfa Romeo 4C and 2018 Porsche 718 Cayman for their looks, handling, performance and pricing. Each of these cars is outstanding, so much so that it will be difficult for some buyers to choose, so below is a side by side comparison which will help in this regard.

Design & Style

These two vehicles are spectacular when it comes to looks. This is especially true for the Alfa Romeo 4C, with its triangular front grill, oval-shaped headlights and sporty side profile. The interior is just as nice, with plush leather seats design to relax passengers with navigational controls that are in all the right places. The Porsche Cayman is also a true gem, with sleek, aerodynamic curves which adheres to the high society style that the brand has become known for.

Technology & Safety

Both the Porsche Cayman and Alfa Romeo 4C incorporate the latest in safety tech and gadgets, so long as it does not hamper their performance. After all, both of these cars were designed with speed in mind. Drivers can expect surround sound, climate control which is dual zone, Bluetooth connectivity and infotainment, but neither of these cars are SUVs so don’t expect the same number of amenities. The Alfa Romeo 4C has a fuel economy of 24 mpg while the Porsche 718 Cayman has a fuel economy of 21 mpg. Both seat a maximum of two passengers, and have performed well on safety tests.


The Porsche Cayman has a higher fuel capacity than the Alfa Romeo, with 14.3 gallons versus only 10.5 gallons for the 4C. Each car uses rack pinion steering with a standard four-wheel anti-brake system. The Porsche weighs more, at 2,943 pounds versus 2,465 pounds for the Alfa Romeo, but both utilize aluminum wheels, both in the front and back. When it comes to engines, the Porsche Cayman houses a Premium Unleaded Intercooled Turbo H-4 with 280 horsepower at 1950 rpm, which surpasses the Premium Unleaded Intercooled Turbo I-4 engine housed in the Alfa Romeo 4C, which produces a maximum of 258 horsepower at 2200 rpm.

The Bottom Line

Both of these cars are closely matched for a number of metrics, which means that any metric where one has an advantage matters a great deal. In this case, the biggest difference between the two is in the performance of the engine, where the Porsche 718 Cayman is simply superior. Throw in the fact that the Alfa Romeo sacrifices too much for its looks, especially comfort, it becomes clear that the Porsche 718 Cayman wins.
