Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Recharge Wrap-up: Cruz defends ethanol stance, Bloomberg gets EV numbers wrong?

Republican presidential hopeful Senator Ted Cruz is defending his stance against ethanol subsidies in an opinion piece in The Des Moines Register. In the piece, Cruz says he doesn't oppose ethanol, but opposes mandates and subsidies, favoring a "free and fair energy marketplace," and an "'all of the above' policy." "We should embrace all of the energy resources with which God has blessed America: oil and gas, coal, nuclear, wind, solar, and biofuels and ethanol," says Cruz, "But Washington shouldn't be picking winners and losers." To farmers' benefit, Cruz says he would enforce antitrust laws against those who try to keep ethanol out of the marketplace, and fight the EPA's hard blend walls prohibiting higher amounts of ethanol in gasoline.

While the Bloomberg article, titled "Plug-in Electric Autos Left Behind in Record Year," accurately points out a slower year for EVs, it claims sales slipped 17 percent in 2015. According to data from Hybrid Cars, that decline was just 2.88 percent. Hybrid Cars claims that Bloomberg lumped a number of PHEVs with regular hybrids when it calculated the faulty data.

CTS allows a remote connection to the car, enabling customers to perform a variety of functions from afar. This includes adjusting climate control and programming charging from a smartphone.

Nissan recalls 3.5 million vehicles over airbag sensor

Nissan is recalling 3.53 million vehicles globally – 3.2 million in the United States – because the front passenger airbag may or may not deploy properly in the event of a crash. In affected vehicles, the occupant sensing system may not properly register a person sitting in the passenger seat. Passenger-side airbags in roughly 622,000 Nissan Sentra models built between 2013 and 2016 may deploy in crashes when they shouldn't, such as when a child is in the seat. 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, and LEAF, 2013-2017 Nissan Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60 and Q50, 2014-2017 Nissan Rogue, 2015-2016 Nissan Murano, Chevrolet City Express and 2013 Infiniti JX35 vehicles suffer from the opposite problem. In those models, the airbag may not deploy when it is supposed to. Nissan is aware of at least three crashes where airbags in one of the above models did not function properly, resulting in "moderate injuries." There have already been four recalls since 2013 for similar issues in Nissan vehicles. If you own one of these cars, expect a letter from Nissan in short order (or from GM if you own a Chevy City Express).

SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, LEAF and Sentra, 2013-2017 Nissan Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60 and Q50, 2014-2017 Nissan Rogue, 2015-2016 Nissan Murano, Chevrolet City Express and 2013 Infiniti JX35 vehicles. In these vehicles, the front seat passenger Occupant Classification System (OCS) may incorrectly classify an adult passenger as a child or classify the seat as empty despite it being occupied. As a result, the passenger frontal air bag may be turned off and not deploy in the event of a crash. CONSEQUENCE: If the passenger frontal air bag does not deploy as intended in the event of a crash, the passenger is at an increased risk of injury. REMEDY: Nissan will notify their owners. Chevrolet City Express owners will be notified by General Motors.
