Mazda Miata 25th anniversary display is roadster heaven on Earth

As part of the celebration of the 25th anniversary of the MX-5 Miata, Mazda has put together a rather large display at its New York Auto Show booth, showing off significant models from the diminutive roadsters history.
The display represents a healthy split of volume models, with cars 14, 15 and 17 sitting alongside cars 500,000 and 700,000. There are also more than a few concept cars in the offering, such as the Super20 Concept we drove a few years back, as well as older offerings, like the Club Racer concept from the 1989 Chicago Auto Show, the M-Speedster from the 1995 Chicago show and the M Coupe from the 1996 New York Auto Show.
We've put together a gallery of images of the historical Miata display, which you can view above. Take a look and then let us know which of Mazda's awesome roadsters is your favorite.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda expands heritage parts program to include the iconic RX-7

Mazda has added two more cars to its heritage parts program. Joining the first-generation MX-5 Miata will be the second- and third-generation Mazda RX-7. It's something fans of Mazda's rotary sports car have demanded for years, and now Mazda is making good with its loyal fans. According to Japanese Nostalgic Car, the program was kicked off today in Japan with a list of 91 parts, 30 for the second-gen "FC3S" chassis and 61 for the third-gen "FD3S". The list is in Japanese and includes basic bits like bolts and washers, as well as vacuum hoses, seals, and bushings. Such rubber parts are typically the first to deteriorate with age and can be difficult to find in the aftermarket. There's even a throttle position sensor for the FD3S. Mazda says more parts will be added as time goes on. The MX-5 has a catalog of 1,100 parts, so there's room for the RX-7 program to grow. There's no word on whether the program will be expanded to full restoration, as Mazda does with the MX-5 or like the program Nissan announced last week for the Skyline GT-R. Mazda also offers the Miata parts in the United States, but it's unknown whether the remanufactured RX-7 parts will cross the Pacific. However, Japanese Nostalgic Car notes that there are 24,000 RX-7s registered in Japan. Sales of the premium sports car were a fraction of that of the Miata, so it would make financial sense to send some parts our way. The Mazda RX-7 was a flagship of the Mazda brand for decades before its discontinuation in 1995 (2002 in Japan). Though known for its commitment to lightness and stellar handling, it's centerpiece technology was Mazda's rotary engine, making it a unique entry in the sports car world. It also has a rich motorsports provenance, having won over 100 IMSA races. The FC3S was sold in the United States from 1986-92 and a favorite of early tuners and drift racers, which means many were destroyed, making good examples quite rare now. The 1993-95 FD3S, famed for its sequential turbo and stunning design, has been appreciating as a collectible classic in recent years. Looks like they might be a bit easier to restore now.
