Bentley Continental GT Speed

Bentley Continental GT Speed
The Continental GT Speed is the most powerful production Bentley ever and the first to top 200mph (322km/h). A potent addition to the company’s highly successful Continental series, the GT Speed extends the appeal of the Continental GT coupe to driving enthusiasts who place a high value on outright performance and agile handling. The exterior style of the new Continental GT and GT Speed models is defined by a wider, lower air intake and more upright radiator grille that also provide increased airflow to the more powerful GT Speed. Its 600bhp (610PS) W12 engine develops 15 percent more torque and nine percent more power than the standard Continental GT, while engine efficiency is optimised by the use of lower friction, lighter-weight components and a new engine management system.

The resultant performance is exceptional, with a top speed of 202mph (326km/h), a zero to 60mph sprint time of just 4.3 seconds (0-100km/h in 4.5s) and effortless overtaking capability. Both the GT Speed and the 552bhp (560PS) Continental GT benefit from internal efficiency improvements to deliver reduced fuel consumption and CO2 emissions. The Continental GT remains outstandingly quick its top speed is unchanged at 198mph (318km/h), with a 0-60mph sprint time of 4.6 seconds (0-100km/h in 4.8s). At the heart of both Continental GT models is the Bentley 6-litre, twin turbocharged W12 engine, the most compact 12-cylinder engine in production. The 48-valve head employs four camshafts and continually variable valve-timing. Power is transmitted via a ZF six-speed automatic transmission. For the Continental GT, the engine continues to produce 552bhp (560PS / 412kW) at 6100 rev/min and a maximum torque of 650Nm (479lb ft) from1600 rev/min.

The twin, low-inertia turbochargers are a key factor in producing the flat torque curve, characteristic of every Bentley. A new higher output of the W12 engine is specified for the GT Speed, sharing engine efficiency improvements with the GT model. New lighter weight con rods enhance engine response, while new pistons, with anodised compression ring grooves, are designed to withstand increased cylinder pressures. Together with a recalibrated version of the new engine management system, the GT Speed develops nine percent more power than the GT - 600bhp (610PS) at 6000 rev/min. The maximum torque of 750Nm (553lb ft) at 1750 rev/min represents an increase of over 15 percent versus the standard engine. As a result, the GT Speed becomes the first production Bentley to top 200mph (322km/h), with a V-max of 202mph (326km/h). The lightweight, fade-resistant braking system minimises disc distortion under high thermal conditions. Under normal driving conditions the brake discs will last the lifetime of the car. Furthermore, brake pad life is doubled compared with the standard braking system. Complementing the braking systems of both Continental GT models are sophisticated safety systems, including Hydraulic Braking Assistance (HBA), anti-lock braking (ABS), drag torque control (MSR) and Electronic Brakeforce Distribution (EBD). This Bentley features single tone, hide-trimmed multi-function steering wheel in a 4-spoke design,Footpedal with Bentley ‘B’ emblem, Hide and chrome trimmed gear lever with manual shift change facility.
