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.

Recharge Wrap-up: BYD sales surge, new Mazda MX-5, plug-in VW Passat

BYD has enjoyed a tremendous leap in sales since last year, according to Want China Times. Sales from January to April were ten times that of the same period last year, with much of the credit going to government subsidies for clean cars. BYD claims, though, that battery production is limiting the number of vehicles it sells, and that by increasing that production capacity, it will see even more success. BYD's Qin plug-in hybrid, introduced in December, has already sold 4,500 units with another 8,000 orders already placed. Read more here. Mazda will reveal the fourth generation of its MX-5 roadster in September. To celebrate the car's 25th anniversary, the all-new two-seat convertible will debut during simultaneous private events in Spain, Japan and the US on September 3 and 4. Furthermore, the new Miata will be the center of a more public event in Barcelona on September 6. For fans in the US, Mazda will hold a Miatas at Mazda Raceway event from September 5 to 7. The 2016 MX-5 promises to continue to offer a lightweight, balanced design for fun and efficiency. The new Volkswagen Passat will feature a plug-in hybrid version. Volkswagen confirmed the Passat PHEV for Europe at the model's unveiling at the Volkswagen Design Centre in Potsdam, Germany. The plug-in Passat uses a 154-horsepower TSI engine and an 80-kilowatt electric motor for a total output of 208 horsepower. With a full charge, it can travel up to 31 miles on electricity alone. All versions of the eighth-generation Passat use stop-start and regenerative braking. Read more at Green Car Congress. BBC warns that the costs of charging an electric vehicle in the UK could surpass those of fueling a gasoline engine. Not so fast, says The Green Car Website. While the BBC cites charging services like Charge Master introducing fees for rapid charging making it cost about as much per mile to drive as traditional internal combustion engines. The Green Car Website points out that most people usually charge at home for much less, that paying for rapid charging is still not that expensive and that the BBC article misses the point about EVs, anyway.

2016 Mazda CX-5 [w/video]

It's difficult for me to get excited about crossovers. I try hard not to be the stereotypical car guy: ignoring the fact that the rest of the world loves these tall hatchbacks, while yelling, "station wagons make more sense!" until I've voided my lungs of air. Deep down I am that guy, but I work around it. Historically the Mazda CX-5 is one crossover that has been quasi-immune to my knee-jerking. It doesn't weigh two tons, offers a manual transmission (in poverty spec, but still...), and looks faster than its competitors. Most importantly, the CX-5 can round a corner without wobbling like a Slinky at the top of the stairs. No item on that list of plaudits would likely crack the top ten "desirables" for average small CUV shoppers. So, for the 2016 update, Mazda instead upgraded the in-cabin experience along with the requisite nips and tucks to the exterior. I borrowed a 2016 model CX-5 to see whether or not those concessions to comfort affected the car-nerd stuff. And to see if the Mazda could still be my go-to CUV recommendation. Driving Notes The engine options are unchanged for 2016. You can still have the fine, 2.5-liter four-cylinder engine, with its 184 horsepower and 185 pound-feet of torque, or its wimpier 2.0-liter lil' brother. My fully spec'd Grand Touring came with the bigger engine, which feels adequately powerful for the class, but not quick. In an era where turbocharged engines are everywhere, revving the Skyactiv 2.5-liter up to its torque peak at 3,250 rpm takes some commitment. I'm annoyed that there's no manual offered with the 2.5L (a combo I can have in both the Mazda3 and Mazda6), but I don't hate the automatic transmission. The six-speed unit is unobtrusive 99 percent of the time; something I regretfully can't tell you about certain nine-speed autos. There are no paddles to play with, but you can tap the shift lever up and down if you're struck by a need for total control. With a new center console and dash, and the addition of the Mazda Connect infotainment system, the '16 CX-5 feels like a new vehicle from behind the wheel. An attractive, pliant, leatherish material swaths the neat console and surrounding real estate. And the perforated leather seats feel damn near upscale. I think that Mazda Connect's version of the central control knob (with handy adjacent volume knob) is almost luddite-proof in its simplicity. There's no latency between twisting and reaction on the screen.
