2027 Nissan Rogue Hybrid: Drives like an EV, but there's no plug involved
摘要
日产为畅销SUV Rogue推出新款，搭载最新e-Power混动系统。该车采用串联混动结构，1.5升三缸涡轮增压发动机仅作为发电机为电池充电，不直接驱动车轮，驾驶感受接近电动车但无需插电。发动机热效率达42%。文章还提及雪佛兰Volt和本田CR-V混动也采用类似思路，但高速时发动机可直驱车轮。
Nissan has a new version of its best-selling Rogue SUV, and it’s launching the model here with the latest version of its e-Power hybrid system, which Ars tested back in February. Most of the hybrid cars you can buy today are parallel hybrids, which means that they have an internal combustion engine and an electric motor, both of which drive some or all of the wheels—everything works in parallel. But there’s another approach. Instead of connecting the engine to the wheels via a transmission, it can act as a generator and charge the traction battery, which in turn powers the electric motor. Since the engine and motor work in series, this is known as a series hybrid.
That’s mostly how the Chevrolet Volt worked. As does Honda’s hybrid CR-V. Well, mostly; engineers worked out it was more efficient for those cars' gasoline engines to directly drive the wheels at highway speeds, something that to this day makes a certain subset of hybrid car enthusiast irrationally angry. If you know anyone like that in your life, send them to wherever the nearest Nissan dealership is, because the 2027 Rogue Hybrid is exactly what they’ve been asking for.
Series hybrids
Under the hood, with its crisp shut line and slim horizontal lights that give me something of a Range Rover vibe, there’s a 1.5 L, three-cylinder turbocharged direct-injection engine that generates 148 hp (110 kW). It only revs to 5,200 rpm because it’s optimized to charge the battery, not cope with the various loads of an engine connected to a gearbox and the wheels. That also allows the engine to operate at a rather impressive 42 percent thermal efficiency—we would need to look at Formula 1 engines to find higher.
