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.

Airbag recall widens to include BMW, Chrysler, Ford and Toyota

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a roll in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time.
BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall.
Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands

2020 Infiniti Edition 30 models priced

The 2020 model year marks the 30th anniversary of Infiniti, and as announced back in August, the brand is rolling out specially tweaked Edition 30 models across the bulk of its lineup. We now have more details and pricing for the commemorative editions, which are available on the Q50 sedan, Q60 coupe, QX50 compact crossover, QX60 mid-size crossover, and QX80 full-size SUV. The Q50 Edition 30 sedan's starting price is $43,700 with rear-wheel drive and $45,700 is all-wheel drive. The Q50 Edition 30 is priced between the Luxe and Sport trim levels, but its equipment is closer to that of the Sport. Although it's $4,800 cheaper than the Sport, the Edition 30 adds full-speed adaptive cruise control, but it uses the smaller brake rotors of the Luxe trim and it skips the Sport's adaptive damping. Unique Edition 30 elements include dark-chrome 19-inch wheels and exterior trim, black mirror caps, and a black mesh grille. The Q60 Edition 30 coupe is offered as a $4,200 package for the Luxe trim level. Added to the $45,500 base price of the rear-wheel-drive Luxe coupe, and you get a starting price of $49,700 for the Edition 30. All-wheel drive is another $2,000. Exterior enhancements mirror those of the Q50 Edition 30. The Q60 Edition 30 package also adds navigation, an around-view monitor, power-adjustable steering column, memory settings, rear auto-braking, adaptive cruise control, heated seats and steering wheel, and a few lesser items. The QX50 Edition 30 compact crossover builds on the mid-level Essential trim level. It's sold as a package for $1,200 and includes adaptive cruise control, blind-spot intervention, lane-depature prevention, and adaptive front lighting, plus 20-inch dark-finish wheels, dark-chrome exterior accents, a body-color rear diffuser, and a black headliner. For the range-topping QX80, the Edition 30 is a package that adds $3,500 to the Luxe (base) trim level. Besides the dark-chrome exterior trim and dark-finish 22-inch wheels, it includes a rear camera mirror, lane-departure prevention, adaptive cruise control, blind-spot intervention, and a black headliner. On Infiniti's most popular vehicle, the QX60, full details of the Edition 30 are not yet available, but we're told the model will start at $50,850. That represents a $4,700 premium over the Luxe trim level, and includes the content of the ProAssist package as well as the Edition 30 design enhancements.
