With the 2008 L.A. auto show teeming with hybrid concept cars, it's nice to visit with the diesel-powered Hyundai HED-5. The HED-5 gives egg-shaped vehicles a good name, and it does wonders for diesel technology as well. The dual-stage turbo setup gives the Hyundai HED-5 well over 200 horsepower and low emissions. Inside, that's first-class leather covering the "swivel" seats, which blend modernity with comfort.
