2019 Porsche 718 Cayman vs Audi TT vs Mercedes-Benz SLC vs Alfa Romeo 4C

Sports car shoppers are often faced with a difficult decision when it comes time to purchase. With an array of various manufacturers all vying for the same type of customer, competition remains fierce. The Porsche 718 Cayman delivers an optimized balance of handling and power thanks to its rear-drive, mid-engined platform which has been perfected across four generations. If you’re having trouble deciding is the 718 Cayman is the right fit for you, Porsche Ann Arbor is here to help. We’ve assembled this competitive comparison which compares the 718 Cayman against a diverse lineup of rivals. Let’s see how the Porsche 718 Cayman performs against the Audi TT, Mercedes-Benz SLC, and Alfa Romeo 4C.

One glance at the performance data from these two rivals reveals some noticeable differences. Offering greater horsepower and torque than the Audi TT, elements of the track-inspired nature of the Porsche 718 Cayman provide a thrilling experience. As a result, the 718 Cayman can accelerate from 0 – 60 MPH nearly half a second quicker than the TT. The Porsche also has a top track speed of 170 MPH, while the Audi TT tops out at 130 MPH. Also boasting a 171-pound weight advantage over the TT, the 718 Cayman has more agility and sharper handling response.

During high speed cornering and other demanding situations, driving enthusiasts always prefer to have access to critical engine operating information. The Porsche 718 Cayman comes standard with an oil pressure gauge, perfect for keeping an eye on how the vehicle is performing. Audi TT drivers will have to do without this feature.

Other driver-assistive technologies found on the Porsche 718 Cayman provide helpful support when you need it most. For example, adaptive cruise control including Porsche Active Safe (PAS) actively monitors the speed of your vehicle in relation the speed of the vehicle in front using radar sensors. If necessary, the system can react by automatically applying the brakes to avoid or mitigate a collision. Both are extremely useful features, although Audi TT drivers have no access to them.

The final advantage of the Porsche 718 Cayman over the Audi TT is cargo room. Offering three additional cubic feet over the Audi, Porsche drivers don’t have to hesitate when packing that extra suitcase for their next weekend getaway.

Porsche 718 Cayman vs Mercedes-Benz SLC

Next up to challenge the Porsche 718 Cayman is the Mercedes-Benz SLC 300 Roadster. Once again, the 718 Cayman delivers greater horsepower and torque than the rival Mercedes-Benz. Offering a 0 – 60 time almost a full second quicker than the SLC 300, the 718 Cayman provides a far more exhilarating rush of adrenaline down the straightaway. Tipping the scales at 3,296 pounds, the Mercedes-Benz is a great deal heavier than the Porsche which results in handling that’s less crisp and tossable in the corners.

Although the Mercedes-Benz SLC 300 Roadster has a convertible roof, top-down thrills can still be had with the 718 Cayman’s closely-related sibling — the Porsche 718 Boxster. Notable exterior differences between the 718 Cayman and SLC 300 are also apparent. The Porsche sports larger 18-inch alloy wheels, giving it a commanding side profile appearance. It also offers a power-deployable rear spoiler as standard, hinting at the track-inspired engineering.

Standard satellite radio allows drivers and passengers to enjoy their favorite music, sports, news, and more while on the road. Giving you a helping hand in tight spaces, standard front and rear parking sensors take the guesswork out of maneuverability. Porsche 718 Cayman drivers will have almost 5 cubic feet of additional cargo room as compared to the Mercedes-Benz SLC 300 Roadster.

The third and final competitor to face off against the Porsche 718 Cayman is the Alfa Romeo 4C Coupe. Although both models share virtually identical price tags, there are some alarming distinctions between the two.

In terms of performance, again the Porsche 718 Cayman shines with its more powerful 2.0L H4 which produces 300 horsepower and 280 lb ft of torque. Its mid-mounted boxer engine offers an inspired balance of agility and superlative power. Another drastic difference, the 4C Coupe lacks the speed-sensitive power steering found on the 718 Cayman. Drivers will find themselves worn out from muscling the 4C Coupe through the corners.

This same lack of refinement of the 4C Coupe translates to its interior as well. Its seats offer half the adjustability positions as the Porsche and is unavailable with heated seats. Standard satellite radio keeps drivers entertained on the way to their destination inside the 718 Cayman. Navigation systems help you get where you’re going with ease. Alfa Romeo doesn’t offer a navigation system on the 4C Coupe. It also delivers a laughable 3.7 cubic feet of cargo capacity.

Turning our attention towards safety equipment, choosing the Porsche 718 Cayman will provide you with greater reassurance and confidence behind the wheel. Most notably, the Alfa Romeo 4C Coupe lacks side-impact airbags on both the driver and passenger sides. In the event of a side impact, your safety could be completely jeopardized. The Porsche 718 Cayman comes standard with this potentially life-saving feature. Optional blind spot monitoring and a standard parking camera highlight the Porsche commitment to safety, whereas Alfa Romeo fails to make this equipment available to its customers.
