Both 4-cylinder and V6 engines offer sophisticated engine technology, with direct-injection on the 3.8 liter engine and a precise twin-scroll turbocharger with a large intercooler for the 2.0-liter turbocharged engine.
The 3.8-liter Lambda DOHC V6 engine produces 348 peak horsepower at 6,400 RPM, with peak torque of 295 lb.-ft. at 5,100 RPM on premium fuel. In addition, Lambda-engine anti-knock technology gives this V6 the versatility to run on regular fuel whenever required. This direct-injected engine will easily propel the Genesis Coupe from zero to 60 mph in the lower five-second range on its way to an impressive 149 mph electronically-limited top speed. The Lambda V6 intake system also employs an intake sound induction pipe into the cabin to ensure this engine’s aural character matches its visceral appeal.
To further broaden the power band, the 3.8-liter engine uses Dual Continuously Variable Valve Timing (Dual CVVT) and a Variable Intake System (VIS) that helps cylinders breathe most efficiently at both low and high RPM. The combination of high-pressure, precisely-metered direct injection with efficient cylinder breathing results in outstanding throttle response and off-the-line acceleration coupled with remarkable fuel efficiency. The V6 engine uses an alloy block and cylinder heads for lighter weight and thermal efficiency and features durable, quiet timing chains with no scheduled maintenance.
All these technologies serve to give Genesis Coupe 3.8 an impressive power-to-weight ratio of only 10.0:1, significantly lower than the more expensive Infiniti Q60 and BMW 435i.

The turbocharged, intercooled 2.0-liter DOHC inline four-cylinder utilizes a twin-scroll design for its turbocharger with a large intercooler for enhanced thermal efficiency. The twin-scroll design is more efficient at recovering exhaust energy and produces cooler cylinder temperatures compared with a single-scroll design. In addition, a twin-scroll design is more precise, with improved combustion efficiency, reduced turbo lag, leaner air/fuel ratios and more evenly distributed pressure in the exhaust ports, resulting in simultaneous power, efficiency and emissions benefits over a single-scroll type. Also, a large intercooler further reduces intake temperatures, providing denser, cooler air from which to develop even more power.
This turbocharged engine also benefits from Dual CVVT on both intake and exhaust camshafts. The 2.0-liter turbo generates 274 horsepower and 275 lb.-ft. of torque on premium fuel. And, unlike many competitive turbo engines, this turbo’s anti-knock sensors automatically adjust ignition timing and engine mapping to run perfectly on regular fuel, yielding 260 horsepower at 6,000 RPM and 260 lb.-ft. of torque at 2,000 RPM. The turbo engine also features a lightweight cast-aluminum cylinder block and cylinder head. All this gives the Genesis Coupe 2.0T a power-to-weight ratio of 12.3, superior to the Scion FR-S sports coupe and Honda Civic Si.
2014 Genesis Coupe 2.0 Twin-scroll Turbocharged DOHC 4-cylinder Engine
Both V6 and 4-cylinder engines also feature deep, baritone-sounding dual cat-back exhausts to complement efficient breathing on the intake side. For 2014, 2.0L Turbo models also feature an intake sound induction pipe, enhancing driver involvement during spirited driving. To ensure that all this power is evenly distributed to the pavement, Genesis Coupe also offers an available Torsen® limited-slip differential on R-Spec and Ultimate models.
