TESTED: 2013 Hyundai Genesis Coupe 2.0t & 3.8 by DSPORT (1080HD)

Описание: First look at the refreshed 2013 Hyundai Genesis Coupe by DSPORT magazine.

"The 3.8-liter Lambda DOHC V6 engine adds sophisticated direct-injection technology, adding 42 horsepower (a generous 14 percent increase) and 29 lb.-ft of torque (an eleven percent increase). Peak horsepower rises 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. This new 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.


Not to be outdone by its bigger brother, the turbocharged, intercooled 2.0-liter DOHC inline four-cylinder 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.
