Brent Rieder Posted: 8/22/2009 8:43am PDT Mazda should rely on its heritage and core strength (Zoom-Zoom) and understand that the US market will be ready for a sporty Mazda diesel when they have one ready to sell here. That means that many Mazda buyers will not require an automatic tranny and would actually be put off by that requirement. A 2.0L hi-performance diesel in a Miata or 3-series could be breath-taking...with a 6-spd manual.
