Nissan Versa

There are myriad ways the all-new 2012 Nissan Versa Sedan breaks new ground for entry-level compact sedans. And many ways to sum them all up. But perhaps a simple statement is best: Innovation Within Reach.

Knowing that entry-level vehicles are used as “workhorses” – for commuting on weekdays, errand running on weekends and transporting family and friends all week long – the designers of the new Versa Sedan sought to combine five-passenger practicality with a high degree of comfort and refinement. It also offers an unexpected level of available entertainment and connectivity features, such as Bluetooth®, navigation system with 5-inch touch-screen display, Satellite Radio and an iPod®/USB interface.

The Versa Sedan’s new exterior design is also a departure from most current compact sedans, offering a fresh, refreshing design character that is both sophisticated and highly aerodynamic.

“The new Versa Sedan stands out as the only expensive looking car in the segment – with a lot of eye power,” said Castignetti. “Its sculpted, dynamic proportions are modern without being gimmicky, projecting a much higher sense of design value than you might expect in a vehicle with a $10,990 starting M.S.R.P.”

To achieve the new Versa Sedan’s upscale look, the designers gave the exterior shape a strong sense of volume, with a wide shoulder width and a smooth silhouette. In front, Versa Sedan features Nissan’s new signature sedan grille design and jewel-like headlights.

The 2012 Versa Sedan’s all-new front-wheel drive global “V” platform, designated “V” for Versatile, utilizes nearly 20 percent fewer platform components and weighs around 150 pounds less than the previous “B” platform. While retaining the same 102.4-inch wheelbase and 66.7-inch width as the previous generation Versa Sedan, the new model is 1.2 inches lower in height (59.6 inches) and 0.6 inches shorter in overall length (175.4 inches). The biggest dimensional gain, however, is in the visible gain in trunk length – provided by a more compact engine/transmission design that allows for a 2.7-inch increase in rear overhang (the distance from the center of the rear tire to the rear bumper).

The second-generation 1.6-liter HR16DE 4-cylinder engine includes a range of cutting-edge technologies, making it one of the most advanced powerplants in class. For example, while the average engine uses only one injector per cylinder to inject fuel, the new Versa Sedan engine is equipped with two streamlined injectors mounted near the inlet valve for each cylinder. This dual injector system allows a wider injection of fuel, with the smaller nozzles delivering a finer spray (approximately 57 percent finer than the previous generation single injector design’s particle size) to help achieve stable combustion.

The new compact, lighter weight engine also utilizes a twin Continuously Variable Timing Control (CVTC) system mounted on both intake and exhaust ports (versus conventional CVTC systems which are mounted only on the intake port), similar to the system used on the flagship Nissan Maxima. Using a CVTC on the outlet port increases thermal efficiency, decreases inhalation resistance and offers an approximate four percent improvement in fuel efficiency.

Other enhancements include the addition of a piston oiling jet, tuning of the piston top shape and expansion of the exhaust manifold diameter.

“To incorporate the new dual injector system into an entry-level vehicle is very fitting of Nissan’s corporate philosophy of ‘innovation for all’ – bring advanced technology to high volume segments rather than saving them only for high-end machines,” says Castignetti. “The new dual injector system also uses around half the amount of rare metals in the catalyzer by reducing the amount of unburned fuel and hydrocarbon emissions.”

The new 1.6-liter engine is rated at 109 horsepower @ 6,000 rpm and 107 lb-ft of torque @ 4,400 rpm.

The Versa Sedan is available with a 5-speed manual transmission (1.6 S model only) and with a next-generation Xtronic CVT™ transmission. The CVT allows continuous change of the transmission gear ratio by connecting the two pulleys with a metallic belt and changing their diameter by using hydraulic pressure. The new CVT design adds an auxiliary gearbox using planetary gearing, helping improve efficiency.
