2018 Porsche 911 GT3
You might think hanging a 420-pound, 500-hp 4.0-liter hunk of flat-six over the back wheels of the 2018 Porsche 911 GT3 would make it hard to handle at speed (or otherwise). You might also think adding rear-wheel steering would accentuate that skittishness. You, and probably some physicists, would be wrong on both accounts. Sure, on cold tires, in the morning around a roundabout, the race-bred GT3 can, and will, slide its tail sideways without warning. It IS still for the hard-core. But exiting a sweeper at 80 mph with foot to floor? It’s planted like an old oak tree, even over the shiny, red-and-white curbing at Circuit Guadix in southern Spain. Like we said, it IS for the hard-core. The GT3 is the track car from the track car brand. It’s been 18 years since the first 911 GT3 premiered, and since then, it’s gone from hiding a 355-hp 3.6-liter flat-six to today’s 500-hp, 911 GT3 Cup-derived 4.0. It’s the only naturally aspirated 911 you can buy right now. Peak power is at a screaming 8,250 rpm while all 339 lb-ft of twist are available at 6,000 rpm. The seven-speed PDK-equipped GT3 is faster than the stick, with a sprint time of 3.2 seconds using launch control; the six-speed manual takes 3.8 seconds. The GT3 doesn’t get a seventh manual gear like the Carrera; Porsche tells us that’s because the GT3 doesn’t need a cruising gear. It’s not for cruising. The PDK car takes 11 seconds flat to get to 124 mph, which we can basically verify after hammering down arrow-straight, desolate back roads near Granada. Terminal velocities (197 mph, PDK; 198 mph, 6MT) are achieved in top gear for both. The GT3 gets redesigned front and rear bumpers made of lightweight polyurethane and carbon fiber. New front air blades force air to the brakes, and the fixed rear wing is about an inch higher, which puts it right on the horizon line when on a flat road, unfortunately. The total package makes 20 percent more downforce than the outgoing model while keeping the same coefficient of drag. It’s about 2 inches wider and 1 inch lower than the 911 Carrera. A straked rear diffuser hides just under the back end, cleaning airflow underneath.Porsche’s Active Stability Management system is standard and controls the damping on the MacPherson strut front and multilink rear suspension. Auxiliary springs help keep tension on the main springs in back, helping the car stay composed “after rapid and complete deflection,” like when flying over the crest of a hill. The rear steering system works like similar systems from other manufacturers: It uses actuators to angle the wheels up to 1.5 degrees depending on speed.
2018 Bentley Continental Supersports
Bentley announced its fastest and most powerful production model to date: the new Bentley Continental Supersports. A top speed of 209 mph (336 km/h) and a 0-60 mph time of 3.4 seconds (0-100 km/h in 3.5 seconds) make the new Bentley Continental Supersports the world’s fastest and most powerful luxury four-seat car. Similarly, its soft-top sibling, the Bentley Continental Supersports Convertible, is the fastest four-seat convertible in the world, despatching the sprint to 60 mph in 3.7 seconds (0-100 km/h in 3.9 secs) on its way to a 205 mph (330 km/h) top speed. Bentley’s mighty W12 engine, redeveloped for the Supersports with new high-performance turbos and engine hardware, and a torque vectoring system create a Bentley Continental Supersports as agile as it is powerful. Meanwhile, unique styling cues inside and out give the new model a sharpened athletic appearance highlighting its performance potential. As well as offering supercar pace and a highly focused driving experience, there is no compromise in the refined nature of the Continental’s ride quality. This fusion of extremes in luxury and performance make the Supersports the ultimate iteration of a model that has come to define and dominate the grand touring genre. Wolfgang Dürheimer, chairman and chief executive of Bentley Motors, said: «The Supersports name is legendary at Bentley. From the very first Supersports of the 1920s, to the Bentley Continental Supersports of 2009 — and now with the third iteration of this iconic model — it is a name which excites, impassions and thrills.
