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.

Datsun reveals new On-Do budget sedan in Russia [w/video]

When Nissan revived the Datsun brand name, it essentially hit the "undo" button on the rebranding it undertook decades ago. But this time, the Datsun name is being used solely as a budget brand for developing markets. The reborn marque launched in India this past July with its Go hatchback, returned in September with the Go+ minivan and revealed the Redi-Go concept just last month. And now it's back again with the new On-Do sedan.
Launched in Moscow by CEO Carlos Ghosn, the On-Do was designed and engineered in Japan specifically for the Russian market - Nissan's fifth largest worldwide - where it will be built at the AvtoVaz plant in Togliatti. Decidedly budget-oriented, the Datsun On-Do is a four-door, five-seat econo-box measuring 172 inches long, 67 inches wide and 60 inches tall with an 18.7 cubic-foot trunk which Datsun describes as class-leading. Punctuating an otherwise bland shape is a large front grille and lighting front and rear that looks (and very well might be) bigger than the wheels.
Not that the Datsun On-Do needs a big contact patch to transfer power to the road: motivation is provided by a 1.6-liter engine with a grand total of - wait for it... wait a little longer - 87 horsepower. Which might strike you as a reasonable amount of muscle, considering the 400,000 rubles Datsun is getting for the On-Do (but consider that translates to about $11,300). That's a couple grand more than what Nissan gets for the Micra in that other giant northern country, or about the same amount it gets for the Versa in the US (which sells in Russia for 499k in rubles) - both of which are powered by what is in all likelihood the same 1.6-liter four but producing 109 hp. Of course Russia has different tax rates than the United States or Canada, but with such little power, the Datsun would fall into Russia's lowest tax bracket.

Nissan, Mitsubishi Motors unveil light EVs for Japan

KURASHIKI, Japan — Japan's Mitsubishi Motors Corp and Nissan Motor Co unveiled their first jointly developed light electric vehicles (EVs), aiming to draw more Japanese drivers to battery-powered cars by offering low-priced micro models. The two Japanese automakers, part of an alliance with French carmaker Renault SA, were once considered trailblazers in Japan's EV market but have struggled to attract customers and face challenges from fast-growing newcomers such as Tesla. "I'm confident that (the new vehicles) representing the alliance will be a game changer for electric vehicles in Japan," Nissan Chief Executive Officer Makoto Uchida said at an unveiling of the new models in the western Japan city of Kurashiki. The automakers are hoping to leverage their presence in Japan's unique market for micro "kei" cars, which account for nearly 40% of cars on the road in Japan. The three companies' alliance early this year detailed a five-year plan to invest $26 billion on EV development, including kei cars. Nissan, which produces the Leaf and the Ariya electric vehicles, will offer its first light EV, the Sakura, starting at about 1.78 million yen ($13,891) after factoring in a government subsidy, and with a range of 180 km (112 miles). Mitsubishi Motors, maker of i-MiEV electric cars, will release the "eK cross EV" starting from about 1.85 million yen including the subsidy, also with a range of 180 km. Both automakers said they would start selling their new line-up of electric "kei" cars this summer. "People who used to think that EVs are too expensive will become a little more interested in EVs and will be willing to give them a try," said Riho Suzuki, Nissan regional product manager.
