2013 Hyundai Genesis Coupe gets more power
Hyundai rolled out a more powerful and more aggressive looking Genesis Coupe at the Detroit Auto Show.
Under the hood is a 3.8-liter Lambda DOHC V6 engine now with direct-injection technology that adds 42 horsepower (a generous 14 percent increase) and 29 lb.-ft of torque (an eleven percent increase). Peak horsepower been increased to 348 at 6,400 RPM, with peak torque increasing to 295 lb.-ft. at 5,300 RPM on premium fuel. In addition, lambda-engine anti-knock technology gives this V6 the versatility to run on regular fuel. 
Hyundai claims the direct-injected engine will 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 now 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.
Also available is a turbocharged, intercooled 2.0-liter DOHC inline four-cylinder that substitutes a new twin-scroll design for its turbocharger in addition to a larger intercooler with enhanced thermal efficiency. The twin-scroll design is more efficient at recovering exhaust energy and produces cooler cylinder temperatures than the former single-scroll design. In addition, the twin-scroll 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 improvements. Also, a 53 percent larger 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 now generates 274 horsepower (a massive 30 percent increase) and 275 lb.-ft. of torque (an impressive 23 percent increase) 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 cast-aluminum cylinder block and cylinder head. All these improvements give the Genesis Coupe 2.0T a power-to-weight ratio of 12.3, superior to the upcoming Scion FR-S sports coupe and the Honda Civic Si.
Both engines are mated to standard six-speed manual transmissions which have been extensively refined to provide more driver-friendly shift gating and balanced weighting precision. The clutch take-up, feel, and engagement characteristics also have been refined for optimum shifting ease and feel. Both engines now offer an in-house-developed eight-speed automatic with paddle-shift SHIFTRONIC® manual-shifting capability. Each transmission has been specifically tuned to match its engine’s unique power and torque curve characteristics. In addition to the steering wheel-mounted paddle shifters, each automatic offers shift capability via the shift lever according to individual driver preference. A clear LCD readout on the instrument panel shows the selected gear at all times.
Underneath, spring, damper, and bushing ratings all have been precisely recalibrated to match these new powertrains with better road feel, more precise body motion control and improved ride comfort. The Genesis Coupe employs a MacPherson strut dual-link front suspension and a five-link rear suspension setup. The front suspension is mounted to the body via a solid subframe that is lighter and stronger than a comparable multi-piece component would be. To help reduce body roll and tune the Genesis Coupe’s at-the-limit handling for maximum predictability, 23-mm diameter front and 19-mm diameter rear stabilizer bars are fitted.
While all Genesis Coupe models rear-drive the high-performance Genesis Coupe R-Spec and Track models raise the bar even higher with differentiated, track-tuned suspension calibrations. The R-Spec/Track suspension features both firmer front spring rates (seven percent) and rear spring rates (eleven percent), with matched damper rates. The Genesis Coupe R-Spec/Track models also deliver a significant increase in roll control over other versions of the Genesis Coupe via thicker stabilizer bars (24mm front/20mm rear). For 2013, all Genesis Coupes receive improved low-velocity-control dampers for refined ride comfort coupled with improved body control.
In addition, all R-Spec and Track models now receive front strut camber adjustment bolts that can be easily installed in the front strut assembly at their owner’s discretion. These camber adjustment bolts allow approximately -1.5 degrees of negative front camber adjustment for sharper, more responsive apex turn-in and significant understeer reduction in competitive events.
Hydraulic, RPM-sensing rack-and-pinion steering has been recalibrated with an even quicker, 13.8:1 ratio, delivering both linear feel and agile response to driver inputs. This new steering ratio is a full seven-percent quicker than the previous model, yielding intuitive steering response and precision. To further optimize driver ergonomics, telescopic adjustment also has been added to tilt adjustment for 2013.
Brembo® four-piston calipers clamp down on fade-resistant 13.4-inch ventilated front brake rotors and 13-inch ventilated rear rotors on both R-Spec and Track models. All other models get substantial 12.6-inch front ventilated rotors and 12.4-inch rotors in the rear with floating single-piston calipers.
Outside, the Genesis Coupe sports a redesigned front fascia, grille, headlights, LED daytime running lights, fog lights and hood with heat extractor cues. The side view reveals new, a 18- and 19-inch alloy wheel designs with deeper dimensional sculpting. The rear taillights provide a visual spark via premium LED illumination and new contours. The traditional rear-drive sport coupe proportions remain, with a long wheelbase and short front and rear overhangs producing a classic wedge-like profile. Genesis Coupe’s bodyside character line is an innovative “Z”-shaped design that integrates seamlessly with a unique, drop-beltline rear window graphic.
Genesis Coupe’s arching roofline and tapering greenhouse highlight the exterior profile and emphasize the car’s broad shoulders and wide stance. Enlarged openings in the front fascia allow for better engine breathing along with a more aggressive look. Dual asymmetrical exhaust tips integrated with the blackout rear diffuser treatment complete the performance message from the rear.
Inside, the instrument panel crash pad features a stitched-seam appearance for a distinctly upscale look, and the parking brake lever is leather-wrapped on leather-equipped models. The instrument cluster now features an electroluminescent gauge cluster for premium ambience and superior readability. A new driver-side rear seat walk-in assist function has been added for more convenient rear seat access from the driver’s side. Convenient seatbelt assist guides make it easier for front passengers to buckle up.
In addition, driver seat power lumbar support is now available and front seatback pockets are standard on all Genesis Coupes. A center stack multi-gauge cluster with instantaneous mpg, torque level (3.8 models) or turbocharger boost pressure (2.0T models), and oil temperature is standard on all trims. A center fascia tray with cover has been added for enhanced storage, and interior surfaces now have a softer touch with lower sheen for a more up-market feel. Sport front seats with deep side bolsters offer superb lateral support for enthusiastic driving in all trim configurations. Other premium features are an available Infinity® premium audio system and two-stage front seat heaters. Genesis Coupe also offers the convenience of a Proximity Key and push-button start.
Hyundai Blue Link telematics is available on 2013 Genesis Coupe with a 90-day complimentary trial period. The Blue Link platform is available on 3.8 Grand Touring/Track and 2.0T Premium trim levels. Blue Link can be accessed from the buttons on the rearview mirror inside the Genesis Coupe, the web and via smart phone. Blue Link is offered in three telematics service packages: Assurance, Essentials and Guidance.
All Genesis Coupe models feature standard four-channel ABS with Electronic Brake-force Distribution (EBD) to optimize brake performance under various dynamic loading conditions. The system also includes Brake Assist, which provides maximum ABS-level braking force when a panic stop is detected.
All Hyundai vehicles sold in the U.S. are covered by the Hyundai Assurance program, which includes the 5-year/60,000-mile fully transferable new vehicle warranty, Hyundai’s 10-year/100,000-mile powertrain warranty, and five years of complimentary Roadside Assistance.
