2015 Nissan Murano configurator is lux'd and loaded

We just got done driving the all-new, 2015 Nissan Murano and while you'll have to wait just a few more hours for our complete driving impressions, you can at least get online and build your very own example of Nissan's latest CUV, thanks to the company's new configurator. While Nissan has already published the Murano's starting price, this is our first glimpse at the full pricing details. As we said, prices start at $29,650, not counting an $885 destination charge. From there, things, um, increase. Moving from the base S to the mid-level SV will require an extra $3,060, and adds navigation with the NissanConnect telematics system, a power driver's seat, LED running lights, remote start and a USB port for backseat passengers. An additional $4,330 moves you up to the Murano SL, adding heated leather seats, a Bose stereo, AroundView monitoring, an auto-dimming rear-view mirror, a power liftgate and blind-spot monitoring with cross-traffic alert. At the top of the range sits the Platinum, starting at $39,000 ($2,050 more than the SL). It includes 20-inch wheels, LED headlights, climate-controlled front seats, heated rear seats and a heated steering wheel. Regardless of trim, Nissan customers will get about with the help of a 3.5-liter V6 that's been mated up to an Xtronic continuously variable transmission. Adding the optional all-wheel-drive system will bump up the CUV's price an additional $1,600. Head over to the configurator and build your own ideal Murano.

Recharge Wrap-up: Nissan Leaf's UK milestone, SF's renewable diesel

San Francisco's municipal fleet will use renewable diesel, according to Mayor Edwin M. Lee. Switching to the greener fuel will reduce the fleet's greenhouse gas emissions by more than 60 percent. "By changing our fleet's fuel from petroleum to renewable diesel, we're taking action that is good for the global climate, and at the same time promotes environmental justice in our community by leading to cleaner, healthier air for some of our most vulnerable neighborhoods," Lee says. While renewable diesel is more expensive than the petroleum-based product, with government incentives, it could end up saving the city money. Read more from Biodiesel Magazine. Nissan has sold its 10,000th Leaf in the UK. As of July 6, Nissan has tallied 10,161 Leaf sales since its 2011 launch in the UK. More than half of those were sold in the last 12 months. Nissan sold 2,964 Leaf EVs in the first half of this year, an increase of 69.4 percent over last year. "The UK's electric vehicle market is growing at an extraordinary pace," says Nissan's James Wright, "and while it may be too early to talk about tipping points, today's achievement certainly indicates we're well on our way." The Nissan Leaf is the best selling battery electric vehicle in the UK. Read more from EV Meerkat. ClipperCreek has added a new 40-amp EV charger to its lineup.

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.
