The EX37 is powered by a new 3.7-litre version of VQ engine family. Regularly honoured in independent awards the world over, the twin cam 24 valve V6 produces over 310PS and an impressive over 350Nm of torque.
Among its many features, the lightweight aluminium engine features a bed-plate construction. A technique that has been used in motor racing for many years, the resulting two-part construction of the cylinder block is more rigid than a single piece casting. Among engine specialists, this configuration signifies a high-performance sporting engine which is uncompromisingly designed for the highest strength and reliability.
Other benefits include reduced vibration levels and higher engine speeds to be reached consistently without damage.
The VQ37 unit also features V-VEL (Variable Valve Event and Lift) technology to optimise efficiency and, in turn, the balance between power, response, fuel efficiency and emissions.
V-VEL continually alters valve lift and therefore the quantity of air in the combustion chamber. At partial throttle – in stop-go city traffic, for example – it will make a small lift thus achieving a more precise fuel/air mix with lower quantities of both to improve fuel consumption. At full throttle, the valve lift is greater, inducting a larger quantity of air into the combustion chamber.
The result is a more powerful combustion phase increasing torque and power… while the increase in power is balanced by more efficient combustion to the benefit of fuel economy.
Precise mapping of the ECU, meanwhile, helps the engine provide a progressive ‘swell’ of power and torque, providing a ‘building wave’ of acceleration rather than a peaky power delivery.
EX37 will be available with a new seven-speed automatic option with Adaptive Shift Control (ASC).
With its additional forward gear, the new automatic transmission has a wider spread of ratios which benefits both fuel consumption and drivability. The seventh speed is effectively an overdrive ratio, returning improved fuel economy on a steady throttle without compromising in-gear flexibility for overtaking.
Shift points are tuned to keep the engine in the largest part of the torque curve, ensuring there is always a healthy reserve when the driver wants to overtake. The linked ASC system switches between three different programs depending on input from the major control systems throughout the car. The seven-speed automatic transmission also features a manual mode with blip control to enhance the driver’s driving pleasure.
