2020 Toyota Supra Four-cylinder May Come To America

2020 Toyota Supra four-cylinder may come to America

When the 2020 Toyota Supra was revealed at the Detroit Auto Show, only one engine option was announced for the U.S.: a 335-horsepower inline-six. It looks like that will change, though, as California Air Resources Board documentation, originally discovered by Automobile, reveals that the organization certified a four-cylinder version for the 2020 model. This indicates that we'll probably see a four-cylinder Supra in the U.S. soon. The engine listed is a 2.0-liter unit with an eight-speed automatic transmission and is listed as being used in several other BMWs including the already announced four-cylinder Z4 sDrive30i.

We know of two four-cylinder engines being offered in the new Supra in Japan. One makes just 197 horsepower and 236 pound-feet of torque, and the other makes 255-horsepower and 295 pound-feet of torque. This latter one is surely the one listed in the CARB documentation since the numbers match the four-cylinder BMW Z4 exactly, and that model is in the same listing.

Nissan Brings Fascinating Gt-r-derived Cylinder Coating Tech To Altima

Nissan brings fascinating GT-R-derived cylinder coating tech to Altima

Nissan has announced that its Decherd, Tennessee, assembly plant will start using a fascinating cylinder-coating technology in the Altima's 2.5-liter, four-cylinder engine, a technology that the company points out has been used in the high-performance GT-R. This isn't the first application of what Nissan calls its "mirror-bore" technology; it has used the coating process in a number of vehicles. But it's worth taking a minute to examine the interesting advantages being implemented in the Altima's PR25DD engine.

Most engines that feature an aluminum block use a pressed-in iron cylinder liner for durability. Aluminum simply isn't very tough, and a piston (and its steel rings) moving around in an uncoated aluminum cylinder bore would destroy it fairly quickly. Iron is much more durable, yet still much lighter than an entirely iron engine block.

2018 Mazda Cx-5 Gets Cylinder Deactivation, More Standard Features

2018 Mazda CX-5 gets cylinder deactivation, more standard features

Mazda recently announced its new Mazda6 would feature two engines, one of which would be a naturally aspirated four-cylinder engine with cylinder deactivation. Now the company has revealed the 2018 Mazda CX-5 will also get cylinder deactivation on its sole 2.5-liter four-cylinder. For those curious, the system shuts off the cylinders on the ends of the engine to save fuel. Mazda also says that the engine has been updated in a number of other small areas to reduce friction and further improve efficiency. The company hasn't provided fuel economy numbers for the new engine, though.

The updates for the CX-5 go beyond the powertrain, as all trim levels get more standard features. The base-level CX-5 Sport now comes with a leather-wrapped steering wheel and shift knob, blind spot monitoring, and rear cross-traffic warning. The mid-level CX-5 Touring now has the i-Activsense safety feature suite standard, which includes automatic headlights, rain-sensing wipers, adaptive cruise control, lane departure warning, and lane keeping assist. This suite of features is also available as an option for the first time on the Sport model. The top-level CX-5 Grand Touring gets seat memory for two settings, as well as a power-adjustable passenger seat.
