Mazda doubles down with a pair of Threes

Looking to appeal to the compact tuner crowd, Mazda brought two different flavors of its 2014 Mazda3 to the SEMA Show in Las Vegas this week. The Club Sport 3 Concept hatchback (above) has more of a racing vibe to it, while the Vector 3 Concept sedan (right) looks to inject a little extra fashion into the all-new Mazda3.
Hotting up the 3, Mazda stuck with the stock 2.5-liter engine on the Club Sport 3 Concept but added a limited-slip differential and six-speed manual gearbox, the latter of which was lifted from the CX-5 crossover. Other upgrades include coil-over shocks, a performance exhaust, Brembo brakes and an aero body kit - the latter of which will be offered to buyers at a later date.
While the Vector 3 Concept does get some performance bits like two-piece Brembo brake rotors and grippier tires, the focus on this sedan is all about styling. Starting with a custom paint job and ghost stripes, the whole look is tied together with 19-inch, V-spoke Rays wheels.

Ward's releases 10 Best Interiors list for 2014

While we're still a ways off from the automotive awards season proper, where things like North American Car and Truck of the Year, Motor Trend's Car of the Year and Car and Driver's Ten Best are named, that doesn't mean there aren't trophies being handed out to deserving automakers. Ward's 10 Best Interiors being one of them.
As the name might imply, the magazine focuses on the very best interior treatments in the US market. Whereas some awards purposely exclude extreme, high-dollar offerings, Ward's considers them - the only requirement is that a vehicle has a "new or significantly redesigned interior."
Ward's offered up the list of winners in simple, alphabetical order, and it only seems fair to do the same:

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.
