The 2010 Nissan Rogue 2.5-Liter Four-Cylinder Engine
Nissan's compact SUV returns for 2010 with no changes to its standard four-cylinder engine.
The Rogue's only engine is the 16-valve, 2.5-liter QR25DE, shared with the Sentra and Altima sedans. This all-aluminum inline four is an open-deck engine, designed for compactness and light weight. It has chain-driven dual overhead cams; continuously variable timing for the intake valves; Nissan's Direct Ignition System; and twin balance shafts to reduce vibration. In the Rogue, it is rated at 170 horsepower and 175 lb-ft of torque.
Despite the QR25DE's variable valve timing and long-stroke design, which are supposed to enhance low-end torque, most reviewers find this engine annoyingly weak at low speeds. Unlike some other four-cylinder SUVs, which provide good off-the-line grunt, but run out of breath at high revs, the Rogue's 2.5-liter engine provides anemic mid-range response, coming on strongly at higher speeds.
The 2.5-liter engine's 170 horsepower is at the low end for this class. The four-cylinder Toyota RAV4 has 179 horsepower, the Honda CR-V 180 horsepower, and the Chevrolet Equinox 182 horsepower; several rivals also offer V6 engines. The Rogue's performance is not dramatically inferior to its four-cylinder competition, but reviewers wish for more power for safer merging and passing.
The Rogue's standard Xtronic continuously variable transmission (CVT) does not help much. While this transmission works well with Nissan's larger V6s, many critics say it only emphasizes the 2.5-liter engine's lack of power and raucous demeanor. The big four is reasonably quiet when cruising, but it becomes obnoxiously noisy in even moderate acceleration.
The EPA estimates the 2.5-liter's fuel economy at 22/27 for FWD Rogues, 21/26 with AWD. Both are average for this class, comparable to the Honda CR-V and four-cylinder RAV4, but well behind the 22/32 rating of the FWD Chevrolet Equinox. Like most rivals, the Rogue uses regular fuel.

New Jersey BMW 3 Series dealers to add hatchback, hybrid and 4-cylinder 3s
If you’re like me, you want an upscale midsize vehicle that is backed by a reliable company and ranks well against its competitors. And if you’re really like me, you love the BMW 3 Series and all of the exciting models it has to offer. I’m not the only that enjoys the luxuries the 3 Series offers drivers; in fact, U.S. News and World Report ranks the 2010 model number one out of 18 upscale midsize cars. The review goes on to mention that “many in the automotive press consider the BMW 3 Series the best sport sedan built today.” That is high praise from such a well respected publication.
On top of this accolade, the BMW 3 Series holds another jaw-dropping record: Car and Driver has ranked it in its “10Best” cars for 18 consecutive years. BMW dealers in NJ will concur; the BMW 3 Series is simply one of the highest quality vehicles on the market.
Offering balanced handling, near 50/50 weight distribution and suspension tuning biased towards the sporty side of things, the BMW 3 Series has a little something for everyone, including a range of powerful engines to satisfy a variety of needs. The 3 Series even offers a clean diesel option that gives drivers solid fuel economy. That’s a lot of variety chilling out at your New Jersey BMW 3 Series dealership.
BMW dealers in NJ offer 3 Series models with a choice of three powerful engines, and the vehicles benefit from a chassis and suspension tuned for aggressive handling. I’ve had the pleasure of tearing around winding roads in this vehicle, and it hugs curves like they’re going out of style. Serious power and handling sets the 3 Series off against other vehicles in its class.
One of the engine choices you’ll find at your New Jersey BMW 3 Series dealership is a 3.0-liter inline six-cylinder that pumps out 230 horsepower and 200 pound-feet of torque, earning an EPA rating of 17/15 mpg or 18/28 mpg depending on which performance options you couple with. 335 models are equipped with the same engine but add a pair of turbochargers, gaining an engine rating of 17/26 mpg. The twin-turbo diesel engine kicks things up a notch, blasting out an impressive 425 pound-feet of torque and rated 23/33 mpg. The vehicle comes standard with a six-speed manual tranny, but you can also choose an automatic.
Pretty soon, the BMW 3 Series will add a hatchback to its lineup that should do well against competing luxury wagons and small SUVs. That model is set to go into production in 2010. The legendary German manufacturer will also add a four-cylinder to its American 3 Series lineup.
BMW enthusiasts everywhere have raved about the 3 Series for years and years. Now that I’ve finally jumped on the bandwagon, I’m happy to say that I’m content in my conversion. Make sure to check out New Jersey BMW 5 Series models as well. You simply can’t go wrong when you choose a vehicle from the stalwart, reliable manufacturer.
