GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

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.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.
