Nissan Sentra gets mean with 240-hp Nismo concept

Nissan's Sentra Nismo Concept made its world debut at the LA Auto Show today as part of the Japanese automaker's intitiative to expand its performance line of factory performance models, and it's packing a turbocharged inline four-cylinder engine with 240 horsepower and 240 pound-feet of torque - that's 110 hp more than the regular Sentra.
Of course, no high-performance version of any car would be complete without the suspension upgrades to handle the power, and Nissan has fitted Nismo-tuned suspension and a limited-slip differential to the little front-wheel-drive sedan. With such an increase in power, Nissan wisely chose to swap out the stock brakes for the Brembo calipers and discs from the 370Z. Larger 225-millimeter-wide tires are wrapped around 19-inch Rays wheels and contained within wider fender flares. The steering and six-speed manual transmission also were tuned by Nismo.
The exterior gets new aerodynamic bits, such as a revised front fascia, a chin spoiler and a new rear spoiler, while the interior gets a nice set of Recaro seats and a leather-and-Alcantara steering wheel. For more information on the Sentra Nismo Concept, check out the press release below, and feel free to head over to the auto show photo gallery to see the car up close.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

2015 Nissan Murano gets edgier, lighter for NY

Nissan's Murano stands as one of the originators of the crossover movement - it was perhaps the first such vehicle to throw out the idea that a CUV had to look like a boxy, cladded-up sport utility vehicle in order to be successful. Now poised to enter its third generation, the midsize Nissan is not only getting a new look and a host of new technologies, it's getting a new home: Canton, MS.
With dramatic new styling presaged by the Resonance Concept at last year's Detroit Auto Show, the new Murano debuting at this week's New York Auto Show includes a toned-down "V-Motion" nose, and the Japanese automaker's trademark boomerang-shaped light fixtures. Aside from the chunky chrome U-shaped grille element up front, the new Murano's most striking design detail is its cantilevered roof with funky "disconnected" D-pillars, a floating look reinforced by a greenhouse edged in brightwork. Overall, it's a much more bold and expressive piece of design than Nissan's recent second-generation Rogue, fitting, as the Murano has always been on the daring end of CUV design.
Boasting a 0.31 coefficient of drag and a ton of sheetmetal surface development, the Murano's new form is available with LED headlamps and features active grille shutters for improved aerodynamics. The company claims visibility has been improved as well - and not just because of its brilliant available Around View Monitor camera system - Nissan says it has "optimized the angles and thickness of the bottom of the A-pillar," along with fiddling with the size and location of the side mirrors.
