TOKYO — Suzuki's 2010 Kizashi sedan won't be officially unveiled until late next year, but sketches have leaked to the Internet already. The Japanese automaker has previously shown concept versions of the future midsize sedan, with the most recent being the near-production Kizashi 3 at the 2008 New York Auto Show this past spring.The concept had been an edgy-looking and muscular design notable for a sharp V-shaped grille and fitted with a 3.6-liter V6 making 300 horsepower, mated to a six-speed automatic transmission.The sketches, which the U.K.'s Autocar says were intended for the European patent process, show that some of the design features of the concept remain, especially the front end.Suzuki is expected to produce the Kizashi in varieties from four-cylinder to V6 models with four-wheel drive. Autocar suggests the car will be priced in the U.K. starting at the equivalent of $30,200 in early 2010.What this means to you: The sketches show some of that inevitable slide from invigorating concept car to rather ordinary production model. — Laura Sky Brown, Correspondent
