YouTuber TJ Smith is your singing Lyft driver in Nissan Sentra ad

Perhaps you've seen Nissan's latest commercial, promoting the Sentra. It's a fairly simple little spot, showing the compact's driver blaring Billy Idol's Mony Mony, singing along and encouraging other motorists to join in.
We'd have been fine had it been left at that. It's a simple commercial that shows the car with a catchy tune and smiling people. Nissan couldn't leave well enough alone, though, and has come back with this. Starring TJ Smith - the driver from the original ad and an apparent YouTube celebrity famous for the kind of thing shown in the original commercial - the new ad expands on the old, with more people, and more Mony Mony. This time round, Smith is serving as a driver for the Lyft service, who just happens to break into song with his fares in the car.
Scroll down for the full video. If you've no idea what we're talking about, we've also included the original commercial.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Recharge Wrap-up: Tesla Model S in landslide, Plug'n Drive wants EVs

A woman and child survived a landslide in a Tesla Model S. The front of the car was severely damaged with the hood and front fascia badly crumpled. The rear hatch window glass caved in, but while the windshield was cracked, the safety glass held together. While in another vehicle, the occupants could have been crushed by the tree that landed on the car, the cabin structure of the Model S mostly withstood the pressure, saving the humans inside. It's not the typical situation most people think of when considering car safety, but it is a dramatic example of the protection the Model S offers.

Together the cars will drive a combined 400,000 kilometers (about 248,550 miles) emissions-free. The cars - a fleet of Renault Zoes, Nissan Leafs and Nissan e-NV200s - will be used as shuttles for the conference attendees. The Alliance will set up a network of 90 chargers for the event, powered by low-carbon electricity. The residual emissions will be offset through a UN carbon offsetting program.

The group says that adding electric power to more cars, "can make a significant contribution to GHG emission reductions in Ontario, while at the same time benefitting the Ontario economy." GHG are, of course, greenhouse gases. According to the group, there are currently more than 12,140 EVs in Canada. Read more in the press release below. Plug'n Drive advocates for electrification of transportation as a key plank of Ontario's climate change action strategy First ever Electric Vehicle Day at Queen's Park demonstrates the benefits of electric vehicles TORONTO, ON, Oct. 26, 2015 /CNW/ - Plug'n Drive is hosting the first ever Queen's Park Electric Vehicle Day today at 11:00 a.m., providing MPPs from all parties, Ministers, public servants, stakeholders and the public the opportunity to test drive electric cars at all price points and to learn about the environmental and economic benefits of switching from gas to electric.
