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.

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.

Recharge Wrap-up: Rimac Concept One vs. Bugatti Veyron, Tesla Autpoilot in the snow

Watch the Rimac Concept_One and the Bugatti Veyron drive head-to-head along the Croatian coast. Rimac Automobili founder Mate Rimac invited the Earl of Pembroke to drive his 1,088-horsepower EV, while he'd drive Lord Pembroke's Bugatti for comparison. Besides the scenic coastal roads shown in this first film, the pair also drove on a racetrack and an airfield. More episodes – and a drag race – are to come. Watch the video above, and read more at Teslarati. Watch how Tesla Autosteer operates in the snow at night, with no lane markings and no lead vehicle. While Tesla doesn't recommend using Autopilot in these conditions, it seems to manage rather well. Even thought the system shows that it doesn't always recognize the curb, the car doesn't instruct the driver to take control. It's possible that data plays a key role when there aren't other guiding factors on the road, and Tesla's high resolution mapping and the car's GPS could help navigate when there is little sensor input.

Andromeda Power uses its V2V Orca Inceptive onboard charger, which is meant for CHAdeMO to CHAdeMO charging. It requires a lot of equipment, including a CHAdeMO Tesla adapter, but it's definitely one way to feed a Tesla enough juice to get to the nearest charging station. Read more at Inside EVs. Hyundai increase the range of its Tucson Fuel Cell by 30 percent. The next generation of the hydrogen powered Hyundai is expected in early 2018, and range will jump from 265 miles on a full tank to 348 miles. That surpasses the Toyota Mirai's 312-mile range, but not the 366 miles of the Honda Clarity Fuel Cell. Read more at Green Car Reports, or from the Nikkei Asian Review.
