Joining the Continental GT V8
in Bentley’s lineup this year, but not on the floor at the 2012 Detroit Auto Show, is the new Continental GTC V8 luxury convertible, which like its hard-top sibling has also been fitted with a powerful and relatively frugal V-8 option for the 2013 model year.
That option is for a new a newly developed twin-turbocharged 4.0-liter V-8 rated at 500 horsepower and 487 pound-feet of torque.
Lifted from the recently revealed 2013 Audi S8
but tuned for more low-end torque--peak twisting force comes on at just 1,700 rpm--the new V-8 should see the Continental GTC V8 almost match the regular W-12 model in performance but with 40 percent fewer emissions. Yes, 0-60 mph runs should still take less than 5.0 seconds.
Key to its frugality is cylinder deactivation technology, which allows the new V-8 engine to run on just four cylinders during low load situations. Importantly, the change between four and eight cylinders will remain imperceptible to passengers. This is because special hydraulic engine mounts compensate for the different resonances of the V-8 and its V-4 mode.
Other fuel saving features include direct injection technology, low friction bearings, thermal management, brake energy regeneration, and special packaging of the turbochargers to ensure high efficiency.
There’s also a new close-ratio eight-speed automatic transmission sourced from ZF. The transmission has been designed to not only boost acceleration but also help reduce emissions, helping to curb 6 percent of that previous 40 percent figure.
Apart from its lightweight convertible roof, the 2013 Continental GTC V8 is almost identical to the Continental GTC V8 hard-top. Both V-8 models feature red winged 'B' emblems and a black gloss grille to indicate that a different Bentley powerplant nestles in their engine bays. They also feature a unique center console separating the driver and front passenger, as well as their own wheel patterns (20-inch wheels are standard).
