| 11-01-2012 at 08:00: Hyundai Injects Veloster with Turbo | |
|
Although Australia has not yet seen the naturally aspirated Veloster, launches in Australia in February this year, the turbo model is going to be a model well sort after in the US. It is not yet known if Australia will see the turbo model with more details to come later in the year. The 1.6-litre turbocharged GDI four-cylinder engine in the 2013 Veloster Turbo produces 150 kW @ 6000 rpm and 264 Nm of torque from 1750 – 4500 rpm with standard unleaded fuel. The Veloster Turbo is estimated to deliver 8.7 L/100km city and best-in-class 6.2 L/100km highway for manual transmission models. Hyundai’s 1.6-litre Gamma turbocharged engine features a twin-scroll turbocharger that when combined with the GDI system, results in instantaneous power delivery. 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 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. Another advantage is improved low-end torque and faster transient torque response. By adapting the motor-driven electrical waste-gate, the boost pressure is precisely controlled. The back pressure is reduced when turbo boost is not necessary by opening the waste-gate, which improves fuel efficiency. During cold starts, the waste-gate remains open, which results in faster catalyst light-off for reduced exhaust emissions. A GDI fuel delivery system contributes to improved fuel efficiency and lower emissions. This shorter, more direct path of fuel delivery allows for greater control of the fuel mixture at the optimum moment, thus improving efficiency. The fuel is injected by a camshaft-driven, high pressure pump operating at pressures up to 2175 psi. Direct injection also utilises a higher-than-normal 9.5 compression ratios, while achieving a best-in-class93.6 kW-per-litre. The piston heads are “dished” to increase combustion efficiency in the cylinder. Thanks to the integrated stainless-steel turbine housing with the exhaust manifold, not only is the weight and cost of the casting dramatically reduced, the durability of the turbine housing is also improved. In addition, heat energy recovery and thus turbo efficiency is significantly improved based on the fact that a traditional two-piece design effectively insulates some of the heat energy at the joint/gasket area. CUSTOM TWO-WHEEL TUNER INSPIRATION SPORT-TUNED suspension TRANSMISSIONS The Veloster Turbo is mated to a six-speed automatic transmission with steering wheel-mounted paddle-shifter controls rather than the naturally aspirated Vesloster’s DCT. This is due to the increased torque output from the 1.6-litre Turbocharged-GDI engine. The gear ratio spread on the automatic transmission is slightly narrower than the DCT (6.0 vs. 6.38). A narrower spread maintains the engine in the power band when going from one gear to the other. The base Veloster’s DCT is tuned for fuel efficiency and not for the performance feel needed for the Veloster Turbo. OVERALL DIMENSIONS Advanced Standard Safety Technologies VSM works to control two effects. The first is when a driver accelerates or brakes on a surface with varying grip (e.g. slippery on one side and dry on the other) and the vehicle wants to pull in one direction. VSM detects this condition and sends a signal to the MDPS to apply steering assist. VSM counters the pull and automatically provides up to eight Newton meters (Nm) of counter steering. VSM reacts the same way during sudden lane changes or fast cornering. All Velosters feature six airbags—including dual front, front seat-mounted side-impact, and front and rear side curtain airbags. Velosters feature a state-of-the-art braking package. The package includes four-wheel disc brakes and an Anti-Lock Braking System (ABS) including Brake Assist, to provide maximum braking force when a panic stop is detected, and Electronic Brake-force Distribution (EBD), to automatically adjust the braking force to front and rear axles based on vehicle loading conditions. 2013 Veloster Turbo highlights (exclusive Turbo features for U.S. market) Powered by a new 1.6-litre Turbocharged-Gasoline Direct Injection (T-GDI) engine and in-house six-speed automatic or manual transmissionHorsepower: 150 kW @ 6000 RPMBest-in-class highway fuel economy estimated at 6.2 L/100kms(manual transmission)Best-in-class specific output at 94 kW per litreSport-tuned engine intake and exhaust noteSport-tuned steeringUnique front fascia, fog lights and ground effectsHyundai Matte Grey paintUnique 18-inch alloy wheels with chrome insertsProjection headlights with unique LED headlight accentsSide mirrors with turn signal indicatorsUnique LED taillightsSupervision clusterLeather seating surfaces with driver’s lumbar supportHeated front seatsNote: Specifications, features and options relate to the U.S. market Veloster Turbo.
