The success of Mazda's MX-5, or Miata as it has long been known in the U.S, is down to a simple formula.

It's inexpensive, it's fun, it looks good, and it's reliable. It took the best aspects of sports cars from the 1960s and 1970s, but dressed it up with modern comforts and a healthy dose of Japanese sensibility.

Economy has never really been a major aspect of the MX-5 but it might be in future--Autocar reports the next generation of the diminutive sports car could have a diesel option.

The unit would join a standard 1.6-liter, naturally-aspirated SkyActiv gasoline unit, which could be joined again by more powerful variants.

Mazda's consideration of a diesel MX-5 might come as a shock to some, but the company is already generating a buzz around its Sky-D diesel engines, a diesel-powered Mazda6 race car making appearances in some endurance events.

The diesel Skyactiv units promise lower emissions, improved economy and gasoline-style responses--and a smaller-capacity unit could prove potent in the lightweight next-generation MX-5. Mazda is currently aiming for a flyweight target of under 1,800 pounds.

A diesel MX-5 is by no means certain, though--Mazda is unsure whether such a thing would even sell, and the company's engineers favor the higher-revving capabilities and lighter weight of a regular gasoline engine.

For sports car purists, diesel's less-than-enthralling soundtrack might also be an issue, particularly with the roof stowed.

  1. They need to fix the design first. The Miata has been junked up with a bunch of goofy add-on design bits, leftover from Mazda’s various “new directions”. Bulging wheel wells? Yep, they were added to the Miata a while back. Beak-like smiling air intake? Yep, that was grafted on. Mazda 3-ish clear taillights? Yep, paste those on, boys… the result is a stale and over-wrought design that lacks focus and excitement.

  2. Completely agree, on all points!

    I read that they are collaborating with Alfa Romeo on the next generation MX-5, and that in turn could mean that Italdesign and Giorgetto Giugiaro could be involved!

    If that is the case, the next generation MX-5 should look Alfa-Romeo gorgeous...

  3. "Economy has never really been a major aspect of the MX-5 but it might be in future--Autocar reports the next generation of the diminutive sports car could have a diesel option."

    Economy has nothing to do with anything in the case of the MX-5, it is the 310 footpounds of V8-like torque at 1,800 RPM that makes it worth it.

    This is about the Sky-D diesel's performance, which is nothing short of amazing.

  4. The MX-5 will rule the autocross with a diesel! It has an oddball 14:1 compression ratio to reduce weight of internal components. Now if they can just get an aluminum alloy block to work. Unstoppable!

  5. 310 ft lbs is for the 2.2 liter ...not a 1.6 as they mention here. Likely good but far less than 310 you mention

  6. You are right, even so, I would take a diesel sports car over a gasoline one all the time, every time.

  9. yeah, I'd by the diesel to run it on bio diesel if they continue to refuse to build an EV version. More likely I'm going to buy a different affordable and nice EV convertible by a different manufacturer. Unfortunately I can't afford a Tesla Roadster

  10. I love my 2010 Miata, but I would be thrilled with idea of the new diesel as long as I am not giving up the level of performance I currently enjoy.

  11. Diesel engines are roughly 50% more efficient than their gasoline counterparts and can run on a wider range of fuels. They also have considerable torque and are well equipped to pull/carry loads without hindering efficiency. It is not coincidental that more than 50% of all cars sold in Europe are diesel. The real benefit of a diesel engine is that the emission products of biodiesel combustion are easier to manage than that of the alcohol fuels. Developing fuel crops remains a challenge, but is considerably more benign than that of battery manufacturing and disposal and hydrogen production for fuel cells...
