The Sentra SR Turbo shares the majority of the same components with the regular SR variant, but features a new 1.6-liter direct injection gasoline turbocharged inline-four motor. The engine raises power to 188 horses and 177 pound-feet of torque (up from 130 horsepower and 128 pound-feet of torque from models with the regular 1.8-liter inline-four and Xtronic gearbox). The engine can be matched to a six-speed manual transmission, which was previously only offered on the base S model, or the Xtronic unit.

The six-speed manual transmission, which should be the clear choice among enthusiasts, has been tuned to maximize the motor's powerband and torque curve. The Xtronic transmission is a bespoke unit for the Sentra SR Turbo that has also been tuned to bring out the best in the new engine with a wider gear ratio, smaller pulleys, and a sub-planetary gear.

In addition to the new engine and revised transmissions, the Sentra SR Turbo benefits from upgraded suspension including unique front and rear dampers, as well as enhancements to the independent strut front/rear torsion beam suspension. Nissan has also altered the compact car's electric power steering system to reduce the amount of steering effort at low speeds, while providing more feedback on "winding roads." Do Sentra owners take their cars on winding roads? We're not sure.

To ensure that drivers don't get too carried away with the Sentra SR Turbo's power, Nissan packed the sedan with larger brakes and calipers at the front and back. Understeer has also been tamed, with Nissan optimizing the car's active understeer control system.

The interior of the Sentra SR Turbo goes unchanged over the regular SR model. The refreshed Sentradebuted at the Los Angeles Auto Show with an exterior design that echoes the latest Altima and Maxim's V-shaped front end. The change to a turbocharged engine is most likely in response to Honda's move to put the 1.5-liter turbocharged engine into the Civic. There's no word on pricing for the SR Turbo, but it should be more than the $21,245 base price of the Sentra SR.

The Rogue refresh is more than just new fascias and updated features: Nissan gave the crossover a hybrid model. It's available with both front- and all-wheel drive and features a 2.0-liter four-cylinder and a 30-kilowatt electric motor that produce a combined 176 horsepower, six more than the standard Rogue.

The hybrid manages 34 mpg overall with FWD and 33 mpg overall with AWD. Both versions have five mpg better estimates than the normal Rogue, which gets 29 overall with FWD and 28 overall with AWD. Impressively, the hybrid powertrain doesn't affect cargo space much. Behind the first row of seats, the hybrid loses just 0.2 cubic feet, and behind the second row, it loses 1.1 cu ft. You also lose the standard Rogue's Divide-N-Hide flexible seating system, and it's only available with two rows of seats.

We don't know how much the hybrid will cost over the normal model, since Nissan didn't release pricing for either version. Based on the pricing structure for the Murano and the Murano hybrid, the electrified Rogue could cost about an extra $3,000 over the regular gas model.

​Even with the introduction of the hybrid, Nissan still made sure to add the new styling and features to the rest of the Rogue line-up, too. Outside, all Rogues get updated head and taillights, a Murano-inspired V-grille, as well as more chrome details. Inside, the little crossover gets a new flat-bottomed steering wheel with available heating, newly available memory seats and mirrors, and an updated shifter.

Nissan also added new Platinum packages with a nicer leather interior, and base level models now get heated seats and remote start as standard. The company also upped the safety quotient by adding Intelligent Cruise Control, automatic emergency braking with pedestrian detection, lane departure warning and prevention systems and high-beam headlight assistance. Pricing is not yet available for the regular Rogue, but it likely won't change much from the current base price of just over $24,000. It will be available in early November, and the hybrid will be available by the end of the year.
