2008 Hyundai HED-5 i-Mode Concept

(from Hyundai press release) HYUNDAI HED-5 "i-MODE" CONCEPT MAKES NORTH AMERICAN DEBUT AT LOS ANGELES AUTO SHOW WITH NEW ECO-FRIENDLY POWERTRAIN

2.0-liter, Four-cylinder Turbo Engine with Gasoline Direct Injection Approved for U.S. Market Intro in 2010

Hyundai unveiled the HED-5 i-Mode concept at the 2008 Los Angeles Auto Show , featuring an all-new, eco-friendly powertrain making its first-ever appearance for Hyundai. The six-passenger family crossover, which debuted at the Geneva Motor Show earlier this year, combines visionary styling with future technologies and advanced eco-dynamics.

For its North American debut, Hyundai added a turbocharged 2.0-liter, four-cylinder engine with state-of-the-art Gasoline Direct Injection (GDI) that improves efficiency and reduces emissions. The HED-5 i-Mode concept and the new powerplant, called the Theta Turbo GDI, have been green lighted for the U.S. market. Variants of the engine will appear in various Hyundai models. Timing and specifications for a production version of a family crossover similar to HED-5 i-Mode are currently in development.

For the U.S. market, the HED-5 i-Mode reveals a first-ever powerplant for Hyundai, the Theta Turbo GDI. The 2.0-liter, four-cylinder engine uses gasoline direct injection technology. By injecting the fuel directly inside the cylinder in small, precise amounts, the performance and response of the engine improve thanks to the intake charge cooling. Both fuel efficiency and exhaust emissions improve due to the improved combustion. Combine GDI with turbo charging and the result is exceptional power output. The engine has capacity for up to 286 horsepower, greater than most six-cylinder engines on the market, while improving fuel economy by 15-20 percent. The Theta Turbo GDI includes Continuously Variable Valve Timing (CVVT) to further improve efficiency. This ultra-efficient, high-tech gasoline engine will be fitted in various Hyundai models in future model years.
