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.

Five vehicles named Top Safety Pick+ including new Civic, MKZ

In an attempt to help push vehicle safety to a higher level, the Insurance Institute for Highway Safety created a stricter Top Safety Pick+ rating last year, which incorporates a brutal small overlap test and requires cars to get Good ratings in four out of the five categories (and no less than Acceptable in the fifth). Joining the list of the safest cars of 2013, the 2013 Volvo XC60, Lincoln MKZ, Honda Civic (sedan and coupe) and the 2014 Mazda6 have all received the coveted TSP+ rating.
The Mazda6 and Lincoln MKZ have both been completely redesigned, and both received Acceptable ratings in the small overlap test. The Honda Civic, coming off its emergency refresh for 2013, is the first small car to be subjected to the small overlap test, and IIHS says that one of the car's many upgrades includes a stiffer front structure allowing it to receive Good ratings in all categories. Similarly, the XC60 gets all Good ratings thanks to, according to IIHS, Volvo updating the airbag software allowing the side airbags to inflate during the small overlap test.
The 2014 Subaru Forester has not yet been subjected to the small overlap test, so it must make do with just a Top Safety Pick rating until the IIHS tests small utility vehicles, which is expected to happen later in the spring.

Most reliable cars and trucks of 2022

Related: Least reliable cars and trucks of 2022   For years now, Consumer Reports has been one of the most prolific sources of vehicle reliability data around. The organization tests a number of vehicles each year and surveys its members on various automotive topics, including reliability. The results of its 2022 annual auto survey are in, and the list of most reliable vehicles has been revealed. Unsurprisingly, Toyota and Lexus dominated the list of most reliable vehicles, but BMW and Mini snuck into the top 10 as well. The list includes: Toyota Corolla Hybrid: 93 Lexus GX: 91 Mini Cooper: 89 Toyota Prius: 89 Mazda MX-5 Miata: 85 Lincoln Corsair: 82 Toyota Corolla: 81 Subaru Crosstrek: 80 BMW 3 Series: 80 Toyota Prius Prime: 77 In terms of the most reliable vehicle type, Consumer Reports says that sedans remain the best choice. Their average score is 58, which is notably better than SUVs’ average score of 51. Minivans and pickup trucks are lower, at 44 and 39, respectively. As Consumer Reports notes, many sedans are older models that have allowed their manufacturers to iron out the wrinkles, making them more reliable. Domestic automakers' SUVs and trucks performed better in the survey than their imported counterparts, with scores of 45 and 41, respectively. The study also showed that hybrids and plug-in hybrids are becoming more reliable, and have climbed the score ladder to the tops of their segments in many cases.  Consumer Reports says its study includes 17 trouble areas, including small stuff like creaks and rattles and much larger problems like drivetrain failures. The organization states that it weights each issue based on its severity to create its predicted reliability scores, with 100 being the best. A car must be in production for at least two model years to be considered for the list.
