Race Recap: 2013 Bahrain Grand Prix follows the template of this year and last [spoilers]

The sand, the wind, the penalties, the contact and the one crash - all of them collided to make the Bahrain Formula One Grand Prix a surprise affair from day to day and lap to lap. Oh, and did we mention the tires? Pirelli made a last-minute swap after the amusement park ride that the Chinese Grand Prix turned into with the soft compound tire, and brought medium and hard compounds to the desert. That didn't stop things from falling apart for some teams - literally - and that didn't stop the one team that seems to love the hard compound Pirelli tire.

Nissan and Infiniti recall 1.2 million vehicles because backup camera might go blank

Nissan North America has issued a recall for more than 1.2 million vehicles due to the ability to change backup camera settings to the point where there is no image in the display. The recall, which was filed with NHTSA on Sept. 12, 2019, includes cars, trucks, crossovers, SUVs, vans, and coupes across both the Nissan and Infiniti lineups.  Reported by Automotive News, NHTSA recall No. 19V654000 affects a total of 1,228,830 vehicles across two brand lineups and more than two dozen models. It includes the 2018-2019 Nissan Altima, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Versa Note, Versa sedan; and 2018-2019 Infiniti Q50, Q60, QX30 and QX80. It also lists the 2019 Nissan GT-R and Taxis, as well as the 2019 Infiniti QX50, QX60, Q70, and Q70L. According to the recall, it is possible to adjust the backup camera and display settings "such that the rearview image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse." Although this type of occurrence would be extremely rare and most likely a mistake made by the driver, its real possibility means all of these cars are technically breaking the law. Federal Motor Vehicle Safety Standard (FMVSS) No. 111, "Rear Visibility," says so. According to Automotive News, this recall is not limited to the United States and also affects vehicles in Canada, South Korea, and Israel. The recall begins Oct. 19, 2019, and Nissan will provide affected customers with a free software update to fix the issue.        

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.
