Nissan Murano hybrid greens up Shanghai

Nothing says summertime like a muscle car with a ragtop. Or, in China's case, a hybrid crossover SUV, right? So it's a good thing Nissan plans on starting sales of a hybrid variant of its Murano in China for the upcoming warm weather season. Nissan showed off the Murano Hybrid at the Shanghai Motor Show with a supercharged engine that is paired with an electric motor. The company says the powertrain will deliver the fuel economy of a 2.0-liter engine and the power of a 3.5-liter V6 engine. Nissan didn't release actual specs of the engine nor any fuel-economy figures. Back in 2013, Nissan was working on expanding its hybrid choices, including hybrid variants for both the Murano and the Rogue. This powertrain choice makes some sense, since it could be difficult to wring a decent single-charge range out of those relatively heavier vehicles if they were all-electric. With that in mind, take a look at Nissan's press release below. NISSAN APPEALS TO CHINESE WITH TWO WORLD PREMIERES: LANNIA AND MURANO HYBRID AT AUTO SHANGHAI 2015 Lannia makes global debut to capture the hearts of young Chinese customers All-new Murano Hybrid offers excellent fuel economy and driving performance in the luxury SUV segment Customers in China can begin ordering GT-R Nismo and 370Z Nismo today SHANGHAI, China (April 20, 2015) – Nissan unveiled two all-new production models, Lannia and Murano Hybrid, along with two Nismo products, GT-R Nismo and 370Z Nismo, at Auto Shanghai 2015. "These innovative vehicles represent the start of an exciting new chapter in the story of Nissan's presence in, and commitment to, China," said Nissan President and CEO Carlos Ghosn. "Nissan's growth strategy in China will continue to reflect our commitment to use local engineering and manufacturing. And we will maintain our support for China's efforts to promote more efficient and sustainable transportation. On both of these fronts, Lannia and Murano Hybrid will lead the way forward." Highlights of the Nissan display: Building on Nissan's longstanding success in the sedan market, Lannia delivers a fresh, distinctive personality that China's young generations embody. As the first product developed and designed for the young Chinese generations, especially those in their 20s and 30s today who are seen as energetic trendsetters, Lannia is a tangible expression of the company's commitment to China.

Roller coaster or racecar, which pulls more Gs?

Looking for a thrill? You're not the only one. You'll find kindred spirits at airfields going up for a skydive, atop bridges and towers with bungees attached to their feet and standing in line for roller coasters at the local amusement park. But you'll also find them in the paddock at the racing circuit.
So what's the commonality? G-force. It's like gravity, only in each of these cases, it's experienced by human invention. But which activity subjects your body to the greatest amount of g-force? That's what Nissan set to find out.
Before putting them back in the cockpit, Nismo sent out two of its young hot-shoes - Jann Mardenborough and Mark Shulzhitskiy - to an amusement park in the UK with a camera and a g-force meter to find out if any of the coasters could produce as much lateral gravitational force as an LMP2 racing car. See what they found in the pair of videos, below.
