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.

Nissan announces 5-year/100,000-mile bumper-to-bumper warranty for commercial vehicles

Nissan is a relative new-kid when it comes to the commercial van market in the US, with its commercial vehicles division only introducing the first NV vans in February 2011. But Nissan isn't letting its newcomer status keep it from challenging the established players in the segment. The company's latest shot over competitors' bows is announcing that, starting for the 2014 model year, its NV Cargo, NV Passenger and NV200 Compact Cargo vans carry a best-in-class, five-year/100,000-mile bumper-to-bumper warranty. Their powertrain coverage also gets a 40,000-mile increase to five years/100,000 miles.
The new warranty is a huge leap over adversaries in the segment and should lure in some buyers looking for a longer term of coverage. The Mercedes-Benz Sprinter, Ram ProMaster, Ford Transit and Transit Connect all carry a three-year/36,000-mile bumper-to-bumper warranty. The Fords offer five years and 60,000 miles of powertrain coverage, while all of the others increase that to 100,000 miles. Until this announcement, Nissan had the standard thee years of coverage, as well.
The Japanese automaker is clearly hungry to grab a bigger piece of the commercial van pie. Its heavy-duty NV vans have a relatively small 5.3 percent market share in their segment as of May 2014, according to the company's figures, but the NV200 is doing better with a 19.4 percent share. The division as a whole is on the upswing, though, with sales up 88 percent so far in 2014. With just a few years under its belt, Nissan Commercial Vehicles seems unafraid to challenge the status quo in the segment. Let's see how buyers respond.

Infiniti is pulling out of Western Europe, cutting models

BEIJING — Nissan's premium brand Infiniti has announced it will exit Western Europe early next year, as it restructures its global operations and focuses on the world's top two auto markets. Infiniti said it will discontinue the Q30 sedan and the QX30 sport-utility vehicle and cease their production by the middle of 2019 at Nissan's manufacturing factory in Sunderland, England. Both models are sold globally but produced only in Britain. The QX30 is sold in the United States. The move comes as Infiniti seeks to divert its resources to markets with bigger opportunities, such as China and the United States, from a region where non-European premium brands are struggling to compete against local players such as Audi, BMW and Mercedes-Benz. Nissan also recently scrapped plans to build its new X-Trail SUV in Britain amid the uncertainty surrounding Brexit, saying it had taken the decision to optimize its investments by building the next generation model in Japan. "Western Europe remains the most challenging and competitive region for premium cars," Infiniti's chief spokesman, Trevor Hale, told Reuters. Infiniti's sales in western Europe almost halved last year to 5,800 vehicles. In addition to the tough competition, the Japanese premium brand, headquartered in Hong Kong since 2012, has struggled to effectively meet emissions and other regulatory requirements in the region, Hale said, referring to stringent Euro 6 emissions requirements and other regulatory challenges. "The commercial reality for Infiniti in Western Europe is that there is simply no visibility of a viable and sustainable business, especially given the regulatory challenges," he said. Infiniti said an exit from Western Europe will allow it to focus on its initiative to electrify a good portion of its product portfolio from 2021 and discontinue diesel offerings. The brand plans to focus more on its SUV lineup in North America, bring five new or significantly-redesigned vehicles to China over the next five years, improve quality of sales and residual value and realize more synergies with Nissan. "This is all part of Infiniti's vision to become a top challenger brand in the premium segment," it said. As it prepares to withdraw from Western Europe, Infiniti said it is working to find alternative opportunities for employees who would be affected, consulting with employee representatives where necessary and identifying opportunities for transition and training support where appropriate.
