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.

Nissan e-NV200 electric taxi comes to Amsterdam

Amsterdam's Taxi Electric liked its two-plus years with an all-Nissan Leaf electric vehicle fleet so much that it just got bigger, or at least with its vehicle choice. The company, which says it's the first private-taxi outfit to boast an all-electric fleet, is going to start adding Nissan e-NV200 electric compact vans to its stable of vehicles. The company started out with its Leaf fleet in late 2011 and has since put about a million miles on the 25 EVs. Nissan said in January that the new electric van will start being tested by FedEx here in the state and it has already been put through the wringer by FedEx in Singapore, Japan and Germany. Last September, Nissan said it was in the "final development phase" of the electric compact van and would start selling it to the public this year, though it wasn't real specific with details. That month, it was also announced that the vehicle, which uses the same drivetrain as the Leaf, would go into taxi service in Barcelona sometime this year. Nissan representatives didn't immediately respond to a request for more details on when the model would start public sales, how much it would cost and what it's single charge range is. Until we hear back, you can check out the official press release below. This summer Taxi Electric becomes the first taxi company in Amsterdam to adopt the zero-emission Nissan e-NV200 Taxi Electric first 100% Nissan LEAF fleet since November 2011 Pioneering Amsterdam-based company have covered 1.5 million km demonstrating Nissan EVs' quality and reliability AMSTERDAM, Netherlands – Taxi Electric will be the first private taxi company to add the new 100-percent electric Nissan e-NV200 taxi to its green-energy zero-emission fleet. The combination of Nissan's innovative zero-emission technology, in the form of the 100-percent electric Nissan LEAF, and Taxi Electric's ground-breaking city transportation model have been a recipe for success since the start of operation in 2011. Now the two companies have teamed up again to build on this success and take the next step forward by introducing the game-changing all-electric Nissan e-NV200 taxi this summer. Amsterdam-based Taxi Electric operates a fleet of 25 Nissan LEAF vehicles. It was the first private taxi service to switch to a fleet of 100% electric taxis in 2011. The Dutch company's fleet of Nissan LEAFs has now amassed a trouble-free 1.5 million km in taxi operations – proof of the electric vehicle's high quality and reliability.

Infiniti Q50 Eau Rouge gets the heart of a GT-R [w/video]

There has been ongoing talk of an Infiniti using the Nissan GT-R powertrain practically since the moment the Nissan's flagship sports coupe hit the road. While the rumors have gone back and forth over the years, they have never completely gone away. It seems Infiniti is finally turning an ear to the screams of its most vocal enthusiasts with an updated version of the Q50 Eau Rouge concept boasting a modified version of Godzilla's engine and all-wheel drive system debuting at the 2014 Geneva Motor Show. It's even taking things a step further and granting it a new, seven-speed transmission to replace the Nissan's six-speed.
The latest evolution of the Eau Rouge packs the same 3.8-liter, twin turbocharged V6 found in the GT-R but with a unique tune of 560 horsepower and 443 pound-feet (600 Newton-meters) of torque. That makes it 15 hp more powerful than the standard 2015 GT-R but gives up 20 lb-ft of torque. Power gets to the ground through the GT-R's all-wheel-drive system. Infiniti predicts that the Eau Rouge would sprint to 60 miles per hour in less than 4 seconds and on to a top speed of 180 mph.
According to Infiniti Communications Senior Manager Kyle Bazemore in an email to Autoblog, the modded GT-R powertrain was not the only choice for the Eau Rouge. It also considered "developing a high-power sports diesel" and hybrid versions with an electric supercharger. However, "this was the clear solution for this concept car," Bazemore said. Other than the drivetrain, the Eau Rouge in Switzerland is identical to the one shown in Detroit. Sadly, it is not confirmed for production; so we might not be getting the fabled Infiniti GT-R sedan any time soon. Still, we can hope.
