New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver.

It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

Hurricane Sandy cost automakers 15,000 vehicles, may have ruined up to 200k

Hurricane Sandy was the largest Atlantic storm in US history, and its total economic impact is just now coming into view. According to Automotive News, Toyota, Chrysler, Nissan and Honda are set to scrap around 15,000 new vehicles ruined by the storm. Nissan alone accounts for about 40 percent of those, with 6,000 Nissan and Infiniti models deeded "un-saleable" due to damage. The company saw 56 dealerships shuttered due to the storm, but 51 of those have since reopened.
Toyota, meanwhile, had some 4,000 vehicles at its Newark port facility, and of those, 3,000 may be scrapped. An additional 825 were dealer inventory when they were ruined. Honda and Acura dealers are reportedly sending 3,440 vehicles to the salvage yard. By comparison, Chrysler weathered the storm fairly well with 825 units destroyed, while Hyundai suffered only 400 lost units and Kia scrapped around 200.
As you may recall, Fisker also suffered some losses, and Automotive News reports the manufacturer saw 320 Karma models damaged beyond repair. Ford and General Motors have yet to come up with estimates, and no automaker has commented on the full cost of replacing the vehicles.

Nissan, Infiniti recall more than 130,000 vehicles for potential fuel leak

Nissan and its luxury brand, Infiniti, are set to recall 133,592 vehicles after discovering that fuel could leak out around the pressure sensor, potentially increasing the chances of a fire. While Nissan lists five nameplates in its recall, there are actually only three models affected by the improperly tightened fuel pressure sensor. They include the 2012 to 2014 Nissan Juke, as well as 2012 to 2015 Infiniti M56/Q70 sedans and QX56/QX80 SUVs. Nissan will begin notifying owners of affected vehicles soon, with the recall expected to officially kick off no later than January 26, 2015. Naturally, repairs will be conducted free of charge. Scroll down for the official bulletin from the National Highway Traffic Safety Administration. And stay tuned for more news coming out of the NHTSA offices today. In addition to Honda's expansion of its recall for vehicles with Takata-built airbag inflators, the regulatory body published a huge number of unrelated recalls this morning, helping to stack the total number of called-back vehicles even higher in these last weeks of 2014. Report Receipt Date: NOV 28, 2014 NHTSA Campaign Number: 14V683000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 133,592 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2012-2014 Nissan Juke, 2012-2013 Infiniti M56, QX56, and 2014-2015 Infiniti Q70, and QX80 vehicles. The fuel pressure sensors may not have been sufficiently tightened during production. As a result, the fuel pressure sensor may loosen with vehicle usage and cause a fuel leak. CONSEQUENCE: A fuel leak in the presence of an ignition source could cause a vehicle fire. REMEDY: Nissan will notify owners, and dealers will replace the fuel pressure sensors, as necessary, free of charge. The recall is expected to begin on or before January 26, 2015. Owners may contact Nissan customer service at 1-800-647-7261. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
