The Illicit Love-Child of the Toyota Avalon and the Mercedes C-Class

That would be the 2011 Hyundai Sonata which should go into production early in 2010.

...At launch, the new Sonata will only be available with one engine, a 2.4-liter direct injected four-cylinder...

With over 90 percent of current Sonata sales coming with I4 engines and a firm commitment by Hyundai to meet future CAFE standards early, the company has opted to take a pass on a V6. In single exhaust form (read: GLS and Limited), the four banger yields 198 horsepower and 184 pound-feet. The dual exhaust system on the SE adds two units to each of those numbers...

All transmissions in the new Sonata will receive six forward gears and the base GLS will be available with a manual transmission...

Additional powerplants in V-6 and hybrid formulations appear to be on the horizon.
