With its newest Skyactiv engine, Mazda is trying to change the way people talk about engine output. As it launches a new 250-hp, 2.5-liter turbocharged four-cylinder in the?redesigned 2016 CX-9, the brand that promises zoom-zoom is stressing two things: lots of torque, and real-world fuel economy.
"Instead of horsepower, we want people to start referring to torque," says North American product planning chief Tim Barnes.
Mazda is already thinking this way by designing its engines for responsiveness, and that comes from lots of torque early on in the rev range -- after all, the company's research showed most people don't often push their engines past 3,000 rpm. Keeping the revs low also helps fuel economy, especially on EPA test cycles. The trouble is that drivers don't always see the same efficiency in real-world driving that the EPA testers manage, so Mazda set all of its consumption targets according to driving habits of actual customers who don't drive on a dynamometer in a lab.
所以在设计2.5t的时候工程师特意强化了扭矩输出和响应区间，基于公司的调研结果表示大多用户不会超过3千转，并且低转速可以带来低油耗。
The humble state of tune for an internal combustion with all this modern tech intrigued us here at?The Drive; there has got to be more in this puppy. Ford's smaller 2.3 Ecoboost has greater torque and horsepower, albeit with a lower compression ratio. We reached out to Subaru for more information on the FA24, including information on its state of tune in the Ascent, and the possibility of the engine making its way into future Subarus.
"The engine was designed for torque, not horsepower," a Subaru spokesperson told?The Drive, regarding the FA24's power output in the CVT-equipped Ascent. "It is as quick or quicker than the competition and quite good under full load."
Information on the FA24's peak boost pressure was not divulged, but the spokesperson said there would be "more information available at the launch."
斯巴鲁的新款涡轮也是这个思路。
感觉没有NGA用户专业。
