"It's more than the layout or the tires alone; it's the fine-tuning magic that Porsche's engineers conjure during the development process. The Cayman is a sublime mix of heady handling and a relatively relaxed ride." - Car and Driver
Engine and Transmission
The baby Porsche with a turbocharged 2.0L flat-4 engine making 300 hp and 280 lb-ft torque, engine replaces a flat-6 you'd find in the Porsche 911s. The Boxster S gets a larger displacement turbocharger mated to a 2.5L engine, which takes the horsepower to 350, while the Boxster GTS utilizes a variable geometry turbocharger to churn out 365 hp.
Although the flat-4 is an efficient and balanced engine, the grating noise it makes doesn't meet the refinement you expect from a Porsche. The 6-speed manual is quick and precise, however, not as sharp as the 911. The optional 7-speed dual clutch transmission on the Boxster S gets you steering mounted shift paddles along with the bump in acceleration times.

However, the tiny 2.0L flat-4 engine compared to the 6-cylinder and 8-cylinder engines you can find in the rivals at the similar price point make 400+ horsepower. The Boxster's arch nemesis the F-Type convertible with the twin turbo 2.0L inline-4 engine makes 300 hp and sounds monumental.
Acceleration
The 300 hp engine gets your convertible to 60 in 4.9 seconds from a standstill and through the quarter mile in 12.7 seconds. The Boxster S is much faster taking just 4.1 seconds to 60 mph. The Boxster GTS takes that number down to 3.9 seconds in the mile-a-minute sprint.

The Corvette with its massive V8 makes it to 60 in a blistering 3.6 seconds, the next is the Porsche Boxster making the sprint in 4.9. The Mercedes C-class cabriolet is the slowest through the 0-60 taking more than 6 seconds in the process.
Ride and Handling
The stunning stability and virtually zero body roll through twisty mountain roads, kudos to the low centre of mass from the flat-4 engine and massive grip from the tires, puts the Boxster far ahead of the competition in terms of driving dynamics. The electromechanical steering lifted from the 911 turbo, has been fine tuned to forge a telepathic connection with the driver..
In the city the ride is relatively relaxed and controlled, the throttle response is predictable yet precise. However, if you're looking forward to test the limits, you'd want to spec your ride with the multi-mode Porsche Active Suspension Management system on the Boxster S and GTS, which offers a low-riding Sport-spec mode, as well as a revised Sport Chrono Package and Porsche Torque Vectoring.
Braking
The brakes are larger than ever before, with 13s on the front and 11.8-inch discs on the rear, they deliver powerful stopping force. Weighing less than 3000 lbs, the Porsche's work like a charm not only on tracks but also city streets. The brake pedal is extremely precise and direct, much like the steering.

The M240i convertible has huge 13.4-inch brakes up front and 13.6 at the back, but the curb weight is also much more than the Boxster. The Corvette Stingray also is one of the lighter convertibles but still gets bigger brakes to go along with the V8.
