911 beware! Porsche testing new top-trim Boxster

The Boxster and Cayman are like the scrappy siblings compared to their star brother – the Porsche 911. And now it looks like the rivalry is about to get even more serious, as our spies have captured this hotted-up Boxster doing some winter testing. We've already seen Porsche evaluating a higher-performance version of the Cayman, rumored to be called the GT4. It would reportedly offer a taste of the thrills of the 911 GT3, but at a lower price. The coupe appears to have a convertible twin in this Boxster prototype. The biggest giveaway of their possible relationship is the shared front bumper with larger intakes and an extra opening at the tip of the hood. Although, this one lacks the Cayman's big, rear spoiler in favor of a smaller decklid unit. The good news for fans of shifting for themselves is that this tester is fitted with a manual transmission, according to our spies. Being a prototype, though, there's no guarantee that the gearbox makes it to production. At least in Cayman trim, these higher performance models might use a tuned version of the 3.4-liter flat-six with between 370 and 400 horsepower. Though, an earlier rumor suggested that a turbocharged four-cylinder could sit behind the driver. Until we know for sure, glance at the gallery to see a Porsche that might try to challenge its big brother.

2016 Porsche Cayman GT4 First Drive [w/video]

The 2016 Cayman GT4 is the sort of Porsche that purists fear would eclipse the rear-engined 911. The balance inherent in the mid-engined layout of the rigid Cayman chassis meant that it was only the right combination of horsepower and suspension away from whupping a comparable Carrera. Porsche has been very careful to keep this Cayman from doing that, despite the GT4's improvements. If you think this means the GT4 has been hobbled or hamstrung, it hasn't. Even a sopping wet track at Road Atlanta in Georgia couldn't keep us from crowning it the brash, arrogant upstart prince of the track-toy Porsches. The company got a lot right with this ultimate Cayman. To begin with, it absolutely looks the part it's supposed to play. Our tester wears searing Racing Yellow paint, that large wing looming over the rear lid is standard, and rolling stock comprises huge 20-inch wheels wrapped in Michelin Pilot Sport Cup 2 rubber. The front fascia is altered for both airflow to the radiators and downforce, standard fare for a hot track-ready version. What's unusual is that instead of complicating the look with tacked-on contrivances (ahem, like the GTS's grille insert-within-an-insert), it's simpler, subtler, and more purposeful. Between that front splitter and the wing, expect about 220 pounds of downforce at the GT4's 183 miles per hour top clip. Ergonomically, even with these fixed-back sport bucket seats, this car is nigh-perfect. Out back, things are more complicated but no less coherent. The lip spoiler that spans the trans-tailight area grows into a little ducktail, literally overshadowed by the larger rear wing. Rear diffusers are a requisite in this class, so one is present and functional. Optimized side intakes just aft of the doors cram more air into the engine, and gain a little embossed "GT4" script. Ergonomically, even with these fixed-back sport bucket seats, this car is nigh-perfect. The slightly smaller steering wheel, perfectly sized for the application, and the smooth, precise shift action make wrangling the major inputs like an extension of your own limbs. If you want to be cynical, go ahead and call the GT4 a parts-bin car. The 3.8-liter flat-six is cribbed from the 911 Carrera S, and the front suspension, steering system, and rear brakes from the 911 GT3. Want carbon-ceramic brakes? Then you'll get GT3 parts on both axles.
