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.

Ghosn: 'We are getting there' on making Nissan Leaf profitable

After 19 months in a row of record sales in the US, the money picture for the Nissan Leaf is steadily improving. To date (well, until the end of September), Nissan has sold 63,944 Leaf EVs in the US and a total of around 140,000 globally. The company produces the electric vehicle in three countries: Japan, the UK and the US and has sold more standard passenger EVs than any other automaker. Add all that up and you get to an EV that is just about to be profitable. "We are getting into positive, which is good for this technology." – Carlos Ghosn At least, it is according to Carlos Ghosn, the CEO of Renault-Nissan, who spoke to reporters at that Paris Motor Show this week. "We are getting there [to Leaf profitability]," Ghosn told Automotive News. "Are we amortizing and depreciating everything we have spent? No. But if you look at margin of profit – the direct cost of the car and the revenue of the car – we are getting into positive, which is good for this technology." Automakers are notoriously closemouthed when it comes to sharing specifics about the higher cost of alternative vehicle technologies compared to standard ICE vehicles. Still, statements like this – as well as a knowledge about how long it took Toyota to make money from the Prius and overall industry amortization – show that Nissan could well be sitting pretty when it comes to keeping EVs around for the long term. Given some of the other news we've heard recently, it's got to be nice to have some stability.

Pickup sales may hit 2M units for first time since 2007

Even as fuel prices creep back up, trucks are still a hot item among new-vehicle shoppers. To see how popular pickup trucks still are, you don't have to look any further than how much effort automakers put into the continual one-upmanship of their trucks. Backing this fact up, USA Today is reporting that the segment could top two million sales this year - a total not matched since 2007, though still far from the pre-recession, three-million-unit levels.
Through August, the Ford F-Series continues to be the segment leader with almost 500,000 units sold, but the Chevy Silverado (328,269), Ram 1500 (234,642), GMC Sierra (122,232) and Toyota Tacoma (110,293) are all seeing at least 20-percent sales increases, helping to account for around 1.44 million truck sales so far this year - not including possible outliers like the Suzuki Equator and Chevy Avalanche.
This year alone, General Motors has completely redesigned its fullsize trucks, Ram and Toyota have significantly updated their offerings, the next-gen Ford F-150 will be out next year and Nissan is promising an all-new Titan around the same time with an eventual Cummins diesel under the hood. It would seem, then, that truck sales are poised to continue their upward trend.
