The Genesis Coupe is the most thrilling performance coupe yet from Hyundai and most importantly, it is attainable – It promises to be the most affordable 300 hp sport coupe on the planet!
At the heart of the story are two performance-focused engines: The range-topping, all aluminum 310 horsepower (premium fuel), 306 horsepower (regular fuel), DOHC 3.8-liter V6 Lambda RS. The base engine will be the 223 horsepower (premium fuel), 210 horsepower (regular fuel) 2.0-liter turbocharged Theta.
Based on the highly successful Lambda V6 first introduced in 2004, the high performance RS edition (Racing Sport) of the Lambda features several key modifications which have raised power to a maximum of 303 PS @ 6300 rpm (306 horsepower for US market) and peak torque to 36.8 kg/m @ 4700 rpm enabling the Genesis Coupe to catapult from zero to 100 km/h in just 6.3 seconds. The Lambda RS features all-aluminum construction, Dual CVVT (Continuously Variable Valve Timing) on both the intake and exhaust valves and a revised intake system.
Because of the sporty, low hood line of the Genesis Coupe, RS engineers were forced to redesign the intake and exhaust systems trimming 5 cm from its height.
The exhaust manifold's length and cross section were optimized for reduced resistance which maximizes high speed performance and yields a pleasingly sporty exhaust note. At the same time, the diameter of the intake port in the ETC (Electronic Throttle Control) module was enlarged to improve engine breathing.
Attention was also paid to stiffening the aluminum engine block so it could endure higher stresses while a piston cooling jet was added under each cylinder to reduce thermal loading and prevent heat damage. A further boost in performance was attained by adopting more aggressive camshaft profiles on the Continuously Variable Valve Timing system which governs both the intake and exhaust valves. The V6 is mated to a six-speed ZF automatic with a 3.4 final drive ratio. A six-speed manual is also available and features a short-stroke shifter (under 41 mm), optimized gear ratios and triple cone synchronizers (1st, 2nd and 3rd gears) for smoother shifts.
For economy, Hyundai offers the Theta 2.0-liter inline four cylinder engine with a turbocharger for excellent performance. Maximum power is rated 210 PS @ 6000 rpm (210 horsepower for US market) while peak torque is 30.5 kg-m @ 2000 rpm (30.8 kg-m for US market), sufficient to propel the car from 0–100 km/h in just 8.3 sec. Like the V6, the Theta employs a Dual CVVT system plus a piston oil cooling jet which is positioned under each cylinder to deliver improved cooling and better fuel efficiency.
