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.

Hurricane Sandy cost automakers 15,000 vehicles, may have ruined up to 200k

Hurricane Sandy was the largest Atlantic storm in US history, and its total economic impact is just now coming into view. According to Automotive News, Toyota, Chrysler, Nissan and Honda are set to scrap around 15,000 new vehicles ruined by the storm. Nissan alone accounts for about 40 percent of those, with 6,000 Nissan and Infiniti models deeded "un-saleable" due to damage. The company saw 56 dealerships shuttered due to the storm, but 51 of those have since reopened.
Toyota, meanwhile, had some 4,000 vehicles at its Newark port facility, and of those, 3,000 may be scrapped. An additional 825 were dealer inventory when they were ruined. Honda and Acura dealers are reportedly sending 3,440 vehicles to the salvage yard. By comparison, Chrysler weathered the storm fairly well with 825 units destroyed, while Hyundai suffered only 400 lost units and Kia scrapped around 200.
As you may recall, Fisker also suffered some losses, and Automotive News reports the manufacturer saw 320 Karma models damaged beyond repair. Ford and General Motors have yet to come up with estimates, and no automaker has commented on the full cost of replacing the vehicles.

2014 Infiniti Q50's novel drive-by-wire steering system recalled

The gradual replacement of mechanical components in automobiles with electronic systems brings with it definite advantages, but also poses certain potential dangers. Just think of the inevitable problems you've encountered with the computer on which you're reading these words and you'll know what we mean. But a computer crashing isn't as problematic as your car going on the fritz when its electronic systems fail.
That's what Infiniti is being reminded of with its new drive-by-wire electronic steering system. The Japanese automaker developed and installed the Direct Adaptive Steering System in its new Q50 sedan, but a small number of those cars on the road are now being recalled due to that system.
According to the National Highway Traffic Safety Administration, on a small number of examples, the Q50's optional by-wire system may fail if the temperature in the engine compartment drops below freezing. There's a backup mechanical setup in place should the electronic system fail, but NHTSA says that the backup system may also fail to engage in time to avoid a crash.
