2016 Mazda CX-3 scores 29/35 mpg EPA ratings

Looking for a subcompact crossover that won't cost you too much at the pumps? Your best bet is now the new Mazda CX-3, according to fuel economy figures released by the EPA. Mazda's new baby crossover has been rated by the US government agency at 29 miles per gallon in the city, 35 on the highway, and 31 on the combined cycle. That's in front-drive spec, giving the CX-3 better fuel economy than anything else in its class (at least, that is, with an automatic transmission.) Option it with all-wheel drive and you'll take a slight penalty at 27 mpg in the city, 32 on the highway, and 29 combined. According to Mazda that still "makes it among the most fuel-efficient all-wheel-drive vehicles available in the US." Whichever drivetrain option you go for, the CX-3 packs a 2.0-liter inline-four with direct injection (Skyactiv-G in Mazda-speak) good for 146 horsepower and just as much torque, mated to a six-speed automatic transmission. The first examples will begin reaching American showrooms later this summer.

As Mazda's first foray into the quickly burgeoning subcompact crossover class of vehicles, CX-3 provides those seeking a purposeful, stylish and sporty vehicle option that bucks convention. CX-3 offers standard keyless ignition and backup camera, and is available with features that are unrivalled in its class like Mazda Radar Cruise Control, adaptive LED headlights and Mazda's signature driving experience. Front-wheel-drive models have EPA-estimated fuel economy of 29 mpg city/35 mpg highway/31 mpg combined, while models equipped with Mazda's predictive i-ACTIV AWD have EPA-estimated fuel economy of 27 mpg city/32 mpg highway/29 mpg combined. That makes it among the most-efficient all-wheel-drive vehicles available in the U.S. "SKYACTIV Technology means we don't have to compromise when it comes to performance, efficiency and fun-to-drive dynamics," said Jim O'Sullivan, president and CEO, Mazda North American Operations.

Las Vegas reporter makes literal street food

A reporter in the American Southwest did a test to see just how hot it was this week, and received her just deserts. With a promised high of 115 degrees in the Las Vegas Valley on June 20, Caitlin Lilly and Kira Terry of the Las Vegas Review-Journal decided to find out if they could bake cookies and cook breakfast using just the ambient heat of the day and some handy flat surfaces. First, the pair attempted to bake a couple dozen pre-mixed cookies on the dashboard of a Mazda. Starting around 1:00 pm, they left the cookies on a sheet tray propped up beneath the car's un-tinted windows. By 5:00 pm the cookies were done and, according to various R-J staffers, quite delicious. While the cookies were baking, they decided to make themselves something a little more substantial, something to justify the desert they had baking in the Mazda. They found a nice patch of parking lot and tried to fry an egg, some bacon, and a handful of shrimp. The shrimp cooked quickly, as shrimp are wont to do, but after 20 minutes the bacon only browned at the edges while staying raw in the middle. The egg remained uncooked, unfortunately, since even the hottest asphalt isn't hot enough to actually fry an egg. Record high temperatures are baking the American Southwest and Southern California as the region suffers the effects of a weather phenomenon called a " heat dome." Highs of over 100 degrees were reported throughout SoCal, Arizona, and Nevada, which is surprising for mid-June. The threat of wildfires is already astronomical, and people are suffering from heat-related illnesses. Recent Video:

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.
