Worldwide, Nissan Leaf has outsold next two competitors combined

Nissan may not be meeting some of the more optimistic prognostications with sales of its Leaf electric vehicle, but it's certainly kicking the competition's butt. EV Sales is tracking global sales of plug-in vehicle models and estimates that Nissan has sold almost 172,000 units of the Leaf worldwide. That's more than the two next-best-selling plug-ins combined. Globally, EV Sales estimates, the Chevrolet Volt extended-range plug-in has moved about 88,000 units, while Toyota has sold about 71,000 of its Prius Plug-in Hybrid vehicles worldwide. Fourth-place Tesla Model S is close behind at about 66,000 units. Among automakers, Nissan is also by far the lead dog, but Mitsubishi has leapfrogged Chevrolet among plug-in vehicle makers, as the Outlander Plug-in Hybrid continues to sell well. Impressively, the relatively new BMW i3 has moved almost 23,000 units since its debut in Germany last year. As for Nissan, company chief Carlos Ghosn said at the New York Auto Show earlier this month that the company could sell as many as 50,000 units a year of the Leaf in the US, provided that charging infrastructure throughout the country improves. Earlier this year, cumulative US Leaf sales moved past 75,000 units since its late-2010 launch.

Want a V8 on the cheap? Buy a work truck

In case you didn't notice, V8 cars have gotten pretty expensive. If you want a modern muscle car like the Dodge Challenger R/T, Ford Mustang GT, or Chevy Camaro SS, you'll need between $34,000 and $38,000 for a stripped out example of one. The cheapest of those is the Challenger, and the priciest is the Camaro. These are also the cheapest V8 cars the companies offer. But if you absolutely have to have a V8 for less, there is an option, work trucks. As it turns out, all of the Big Three offer their most basic work trucks with V8s. And because they're so basic, they're pretty affordable, especially when sticking with the standard two-wheel drive. A Ram 1500 Tradesman with a V8 can be had for as little as $29,840, which is a little more than $4,000 less than a Challenger R/T. For a bit more at $30,275, you can have a Chevy Silverado W/T, almost $8,000 less than a Camaro SS. The most expensive is the V8 Ford F-150 starts at a starting price of $30,670, which is a bit over $5,000 less than the Mustang. Of course you'll be in an ultra bare bones vehicle with few comforts, and the price will go up if you add stuff, but we're bargain hunting here, and sacrifices are sometimes necessary. Besides, what you lose in comfort, you gain in loads of cargo space and towing (try to look at the bright side). Also, as a side note, all three trucks are available with optional electronic locking rear differentials. At the discounted price of these trucks, you still get a heaping helping of power. The most potent of the trio is the Ram 1500 Tradesman with 395 horsepower and 410 pound-feet of torque generated by a 5.7-liter V8. Compared with the Challenger R/T, the Ram is up by 20 horsepower and they're tied for torque. The value proposition is even more stark between the two vehicles when looking at the price per horsepower. Each pony in the Ram costs $75.54, while the Challenger charges you $90.91. The Challenger is also more expensive per horsepower than its close competitors. The F-150's 5.0-liter V8 is just barely behind the Ram with 395 horsepower and 400 pound-feet of torque. That's still more power than the Challenger, and it matches the torque of the 2017 Mustang GT. On the down side, it still would be down 20 horsepower on that same 2017 Mustang, and it's behind by 60 horsepower and 20 pound-feet on the new 2018 Mustang GT. The F-150 also just edges out the Mustang in the dollar per horsepower measure.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
