A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Wards names its 2015 10 Best Interiors list

Wards Automotive has named the winners of its 10 Best Interior awards, covering a wide but affordable array of vehicles. Where last year's list contained two six-figure vehicles, including the $372,800 Rolls-Royce Wraith, this year's is, well, a whole lot more reasonable. The publication lists the Mercedes-Benz C400 at $65,000 (which seems off), making it the most expensive vehicle here. That said, we'd argue that the entire C-Class line deserves to make this year's list, owing to its varied and high-quality selection of materials. The other vehicle to break the $60,000 mark, meanwhile, is the $60,675 Ford F-150 King Ranch, which has 327,000 pounds of leather lining its interior. Only one other German car, the BMW i3, and one other pickup truck, the GMC Canyon, managed to make this year's list. Here's the full list of this year's winners: 2014 BMW i3 ($52,550) 2015 Chrysler 300C Platinum ($51,175) 2015 Ford F-150 King Ranch ($60,675) 2015 GMC Canyon SLT ($40,465) 2015 Honda Fit EX-L ($21,590) 2015 Jeep Renegade Limited ($33,205) 2015 Kia Sedona SXL ($43,295) 2016 Mazda6 Grand Touring ($33,395) 2015 Mercedes C400 ($65,000) 2015 Nissan Murano SL ($41,905) See what we mean about the mainstream vehicles? Not only is there a distinct lack of luxury brands, it's the price of some of the vehicles that surprise. The Honda Fit, Jeep Renegade and Mazda6 are very reasonably priced, especially when you compare Wards price with the starting price. The Renegade Limited starts at less than $25,000, the Mazda at less than $22K and the Fit at under $16,000. Head over to Wards for a more detailed explanation of why each vehicle won.
