2013 Hyundai Veloster Turbo Driving Scenes (2012 detroit auto show)

HYUNDAI INJECTS STREET CREDIBILITY INTO VELOSTER WITH NEW turboCHARGED ENGINE 201 horsepower, Ground Effects and Sport-Tuned Engine DETROIT, Jan. 9, 2012 -- Hyundai Motor America today introduced the all-new 2013 Veloster turbo armed with 201 horsepower in a world debut at the North American International Auto Show (NAIAS). Veloster turbo is one bookend to Hyundai's turbocharged sports coupe line-up, paired with the refreshed 274 horsepower, rear-wheel drive 2013 Genesis Coupe 2.0T (turbo) also debuting at the show today. "The turbo further broadens Veloster's hero role in the Hyundai line-up to attract our next generation of buyers," said Mike O'Brien, vice president, product and corporate planning, Hyundai Motor America. "It's powerful, high-tech and fuel-efficient, attributes which we think make Veloster turbo the ultimate innovation in the sport coupe segment." The 2013 Veloster turbo arrives in the Summer of 2012, facing off against worthy competitors such as the Volkswagen GTI, Honda Civic Si and Mini Cooper/Clubman S with a better power-to-weight ratio than all of them, and a unique sport-tuned steering and suspension hardware set.

Hyundai just completed its 24/7 version 2.0 product initiative (seven new or redesigned models in 24 months), with the debut of the 2012 Hyundai Azera. TWIN-SCROLL turboCHARGER AND GDI TECHNOLOGY The 1.6-liter turbocharged GDI four-cylinder engine in the 2013 Veloster turbo produces 201 horsepower at 6000 rpm and 195 lb-ft of torque from 1750 -- 4500 rpm with regular fuel. The Veloster turbo is estimated to deliver 27 mpg city and best-in-class 38 mpg highway for manual transmission models. Hyundai's 1.6-liter Gamma turbocharged engine features a twin-scroll turbocharger that when combined with the GDI system, results in instantaneous power delivery. Twin-scroll turbochargers have traditionally been used on more expensive high performance engines, but Hyundai has brought this technology down its line-up from the Sonata 2.0T. Twin-scroll turbocharger designs have two Exhaust gas inlets divided by split walls inside the turbine housing, with both gas passages controlled by a waste-gate. A twin-scroll turbo recovers even more energy from the Exhaust than a single-scroll turbocharger, thanks to a divided manifold. The twin-scroll design separates the cylinders whose Exhaust gas pulses interfere with each other, resulting in improved pressure distribution in the Exhaust ports and a more efficient delivery of Exhaust gas energy to the turbocharger's turbine. For example, at the start of the intake stroke of cylinder one and when both the intake and Exhaust valves of cylinder one are open (valve overlap period), cylinder three already starts its Exhaust stroke with the Exhaust valve open. If the Exhaust passages of cylinder one and three were connected, the Exhaust gas pulse from cylinder three would increase the back pressure of cylinder one. This would reduce the induction of the fresh air and increase the amount of hot residual gases inside the cylinder. However, with the twin-scroll turbocharger setup, this interference is minimized. The result of this superior scavenging effect from a twin-scroll design leads to better pressure distribution in the Exhaust ports and a more efficient delivery of Exhaust gas energy to the turbocharger's turbine. This in turn allows greater valve overlap, resulting in an improved quality and quantity of the air charge entering each cylinder. In fact, with more valve overlap, the scavenging effect of the Exhaust flow can literally draw more air in on the intake side. At the same time, drawing out the last of the low-pressure Exhaust gases help pack each cylinder with a denser and purer air charge. Maximum Boost from the turbocharger is 18 psi.
