Mazda to Add Diesel Option to New MX-5 Roadster

Date Posted 07-21-2005

HIROSHIMA, Japan — Mazda is about to spring a few surprises on its all-new MX-5 roadster, the car that replaces the much loved Miata.

In addition to the standard 2.0-liter gasoline engine, Mazda is planning to add a high-performance diesel option. A Mazda spokesman told U.K. magazine Auto Express: "There are people working on high-revving diesel engines at the moment, and I can see us using one in the MX-5."

A souped-up gasoline version is also under development, though that won't be powered by Mazda's rotary engine from the RX-8. "There's no reason why we shouldn't build a high-performance MX-5," added the spokesman. "This car deserves a more powerful variant." The 2.3-liter engine from the Mazda 6 is the most likely candidate.

The new MX-5 goes on sale in Europe in November and in the U.S. early next year. Mazda is planning a special numbered launch edition of the car to kick off sales.

What this means to you: Miata lovers, fear not — your car by any other name will hum as sweet. Packaging a bolder moniker with increased performance will make a good thing better.
