Mitsubishi and Renault-Nissan expand partnership, US will get new sedan

Mitsubishi and Renault-Nissan have just inked an alliance that might, hopefully, reverse the ailing fortunes of the Mitsubishi brand in the US market. The big chunk of news is that Mitsubishi will produce two Renualt-based models for sale in the US market, and that they'll be built at the Renault-Samsung factory in Busan, South Korea.
The plans call for a D-segment sedan to be followed by a C-segment offering. Based on the cars built at the Busan factory, that means Mitsubishi will be getting the SM5 and the SM3, a pair of handsome sedans that are based on Renault-Nissan's D and C platforms, respectively. These same platforms underpin a number of US market Nissans (not to mention a number of cars from Renault), namely the Pathfinder, Maxima, Quest and Murano for the D platform and the last-generation Rogue and Sentra for the C platform.
Besides the sedan production, Nissan and Mitsubishi will be expanding their joint-venture company, NMKV, which produces Kei cars for the Japanese market. A new, all-electric offering will be born from the partnership, likely based on a Kei car platform. The partnership between the three brands will also lead to increased sharing of technology, particularly relating to electric cars.

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.

2018 Nissan Kicks vs other tiny crossovers: How they compare on paper

Update: As we now have now driven the 2018 Nissan Kicks and have all the specs and figures available, we thought it was time to update this comparison post. The data chart has been updated with final Kicks information as well as changes to competitors made for 2019. Anyone else have "Pumped Up Kicks" by Foster the People stuck in their heads? Well, you do now. I couldn't be the only one. Anyway, the 2018 Nissan Kicks is a thing. It replaces the Nissan Juke, which Mr. Stocksdale thought was a bad idea and Mr. Myself thought was a smart idea. Nevertheless, neither of us were especially pumped up by the Kicks. However, the majority of car buyers are all about SUVs, and this littlest segment of them has been multiplying like Tribbles in the past few years. The Juke was one of the first of these subcompact crossovers, but it was probably too oddball for a mainstream audience (not to mention inefficient) and never really caught on. Newer competitors certainly didn't help. Well, to see how the Kicks compares to those very competitors, lets fire up the Autoblog Comparo Generator 3000 (TM). Specifically, we'll be looking at those subcompact crossovers with similarly small dimensions, especially low prices and/or a disinclination to offering all-wheel drive. We're talking about the Nissan Kicks vs the Toyota C-HR, Hyundai Kona, Kia Soul, Honda HR-V and Jeep Renegade. Now, if you're interested in literally the exact opposite SUV segment, check out our recent Mercedes G-Class comparo. Otherwise, on to the spreadsheet: Dimensions and passenger space In terms of exterior dimensions, the new Kicks is right smack in the middle of the segment. It's virtually the same as the Honda HR-V, yet manages to eek out a few extra cubic feet of cargo space behind its raised back seat. The Honda and its "Magic Seat" still beats it in terms of maximum capacity, but it sure is close. The Kia Soul has the biggest maximum number, but that's largely the result of being a box. Its small behind-the-back-seat cargo number is likely a better indicator of how much you'll be dealing with on a day-to-day basis. And in that day-to-day way, the Kicks is excellent. Backseat legroom seems to be a Kicks downside, as all but the C-HR surpass it. (Seriously, it's almost impressive how large the C-HR is on the outside but cramped inside.) However, the Kicks' tall greenhouse not only allows for ample headroom, but seats that are mounted high off the ground.
