2014 NAIAS: 2015 RC F Coupe has the most powerful ever Lexus 5.0-litre V8 [Live Photos]

Article by Christian A., on January 15, 2014

The 2015 Lexus RC F Coupe made its debut in the Motor City at the 2014 Detroit Auto Show and as expected, the vehicle looks even better in the flesh. According to Lexus, the RC F Coupe uses a 5.0-liter 32-valve V8 engine that provides increased maximum power at higher engine rpm than previously possible.

For the first time, the RC F Coupe uses the Atkinson cycle at cruising speeds for better fuel economy and switches to Otto cycle at higher rpm. The 5.0-liter V8 generates more than 450 hp and more than 383 lb-ft of torque. Using an eight-speed Sports Direct Shift (SPDS) transmission, the 2015 Lexus RC F Coupe promises to hit 60 mph (96 km/h) faster than the IS F (4.6 seconds), while the top speed will be electronically limited at 168 mph or 270 km/h.

The RC F uses a Torque Vectoring Differential (TVD), which is a first for Lexus, in order to increase driving performance. The TVD has three operating modes: standard, for a balance between performance and stability; slalom, for emphasis on nimble steering wheel; track, for helping with consistent stability. RC F has front and rear coil-spring independent suspension, with monotube gas-filled shock absorbers and ball-jointed stabilizer bars.

The 19-inch forged aluminum wheels helped Lexus reduce the unsprung weight, while the four-wheel power assisted disc brakes (made by Brembo for Lexus) with Anti-Lock Braking System (ABS) and Electronic Brake force Distribution (EBD) and Brake Assist (BA) help the drivers stay safe on the road. In terms of design, the Lexus RC F Coupe is based on the RC Coupe but comes with a new body kit, which transforms it into an aggressive stylish coupe.

The front end is dominated by the signature spindle grille with a subtle F-mesh pattern on the lower half. Moreover, we find a hood air vent inspired by the Lexus LFA supercar and a new active rear spoiler incorporated into the trunk lid that can provide down force at speeds of more than 50 mph.

To the side, front fender ducts in the shape of an L also aid cooling performance while adding to the aggressive stance. Inside, the Lexus RC F Coupe offers uniquely designed components such as combination meters, the steering wheel, seats, ornamentation and pedals, convey a sense of connection with the driver that only a Lexus F performance model can achieve.

As measured, the new Lexus RC F has a length of 4,705 mm, height of 1,390 mm and width of 1,845 mm. Because of its flared and laser-brazed wheel arches, the RC F is around 5 mm wider than the RC. It is also longer by 10 mm and lower by 5 mm. However, both the RC and the RC F have the same wheelbase of 2,730 mm,

Interestingly, each design feature in the RC F contributes to its aerodynamics. For instance, the new RC F features Lexus’s signature spindle grille – with a graduated mesh pattern – flowing to a distinct aerodynamic treatment across the bonnet. Within the grille are cooling ducts bordered by oil coolers. Meanwhile, a large L-shaped cooling outlet located at the rear of the front wing is itself a dynamic styling that also helps in the areas of aerodynamics and cooling.

Meanwhile, the RC F is provided with a raised bonnet that allowed the car to accommodate its powerful V8 engine. The raised bonnet features a centrally located meshed scoop for aerodynamics and cooling. The bonnet smoothly flows to the front wing and through the belt line, it becomes a design feature that helps air flow. The flanks of the RC F are laden with a number of aerodynamic elements that help emphasize the car’s wide and low stance.
