The 2022 Nissan Rogue gets a high-tech variable-compression engine
A lot of people probably don’t know – or care – what’s hiding under their everyday driver’s hood. If it gets them where they need to go and delivers decent fuel economy, who cares about engine horsepower or what type of transmission they use? Well thank Nissan for their attention because a year after the company introduced a completely redesigned Rogue, they swapped the compact SUV’s indifferent 2.5-liter four-cylinder for a turbocharged three-cylinder and paired it with a new one. continuously variable automatic transmission (CVT). Not only does the updated powertrain make the 2022 Nissan Rogue faster and more powerful, it also promises better fuel economy.
One of our few complaints about the new Rogue for 2021 was the average performance of its naturally aspirated 2.5-liter inline-four. With just 181 horsepower and 181 pound-feet of torque, the engine was among the weakest in its class and offered unrivaled acceleration. Most vehicles in this class offer more than a choice of powertrains, including turbocharged or hybrid options, but the redesigned Rogue has retained its unique approach to propulsion. And while that’s still the case, the Rogue’s new main engine is the latest iteration of the innovative, albeit complex, variable-compression turbocharged engine. A 2.0-liter VC-Turbo inline-four first appeared in the 2019 Infiniti QX50 before also powering the high-end versions of the Nissan Altima.
The VC-Turbo’s ingenious mechanism varies the stroke length slightly, allowing the engine to adjust its compression ratio (and displacement) on the fly, between 14.0: 1 for maximum efficiency and 8.0: 1. to allow maximum boost. The Rogue’s new 1.5-liter three-cylinder is essentially the Altima’s 2.0-liter with a cut-off cylinder.
This new, smaller three-cylinder variant generates 201 horsepower and 225 pound-feet of torque, which is 20 horsepower and 44 pound-feet more than last year’s Rogue and 47 horsepower and 48 pound-feet less than the version. 2.0-liter Altima. Notably, the Rogue’s VC-Turbo produces these peak numbers with regular 87 octane rather than the more expensive premium fuel. To compensate for the new torque and quell any three-cylinder scraping, the 1.5-liter receives hydraulic engine mounts. The other novelty is Nissan’s latest Xtronic CVT with a wider gear ratio gap (increased 17 percent to 8.2), reduced friction (down 32 percent) and an oil pump system. dual engineered to increase fuel economy and, during aggressive driving, improve responsiveness to gear changes.
Compared to the old 2.5-liter, the VC-Turbo makes the Rogue considerably more energetic underfoot. Despite the Rogue 2021’s 8.2-second 100mph sprint, the previous powertrain felt relaxed to the point of becoming lethargic, especially during the passing maneuvers. We’ll compare subjective opinion to objective results once we get one on the track, but expect the new Rogue to waste about half a second in zero to 60 mph time. Numbers aside, there’s now a reassuring surge of torque that peaks at 2,800 RPM and continues up to 4,000 RPM, fattening mid-throttle response. The new Rogue delivers its power faster, if not always in a more linear fashion. Crushing the throttle reveals an initial hesitation before a sudden surge of thrust; With variable compression and a continuously variable transmission, there are plenty of variables to align before your throttle input translates into action. Prolonged time with the accelerator close to the ground causes a low roar under the hood, but otherwise the cabin is a hushed and spacious place.
In addition to its increased power, the reduced engine also offers better fuel economy figures. With EPA ratings as high as 33 mpg combined – Nissan has yet to give details on values in the city or on the highway or with all-wheel drive – the front-wheel drive Rogue improves its numbers by about 10 percent. predecessor. For comparison, non-hybrid competitors such as the Honda CR-V and Toyota RAV4 both cap at 30 mpg combined. Since our driving route was limited to around 30 miles of mixed driving on the streets and highways around Detroit, we’ll need an extensive test to assess Nissan’s real-world mpg. (In the case of the Infiniti QX50 with the VC-Turbo, our observed mileage in our road test at 75 mph did not hit the EPA figures, 27 mpg versus 30 mpg on the highway. EPA.)
The short drive allowed us to appreciate the Rogue’s comfortable all-day driver’s seat and the rich interior of the top-of-the-line Platinum. We’re happy Apple CarPlay Wireless comes with the larger 9.0-inch touchscreen, but Android Auto still requires a wire, and we’re not impressed with the display’s low-res graphics. Plus, the built-in navigation system got us lost.
The Rogue 2022 arrives in dealerships in January. All models cost $ 650 or $ 750 more than their 2021 counterparts (depending on whether they’re FWD or AWD), which works out to a price range of $ 27,875 to $ 39,155. We doubt too many crossover buyers will appreciate the technical magic of variable compression, but all should agree that this smart new engine puts the Rogue driving experience more in keeping with the promise of its name.
