context_page_description: The Infiniti M is a line of mid-size luxury cars from the Infiniti luxury division of Nissan. From 2013 on it has been marketed as the Infiniti Q70, reflecting the company's new naming scheme.
  The first iteration was the M30 Coupé/Convertible, which were rebadged JDM Nissan Leopard. After a long hiatus, the M nameplate was used for Infiniti's mid-luxury sedans. First was the short-lived M45 sedan, a rebadged version of the Japanese-spec Nissan Gloria. The next generations, the M35/45 and M37/56/35h/30d, became the flagship of the Infiniti brand and are based on the JDM Nissan Fuga.
context_section_description: The Infiniti M Hybrid, to be sold as the Nissan Fuga Hybrid in Japan where it is the top performance trim there, will introduce Nissan's first in-house developed electric hybrid technology, and the carmaker claims it will double the fuel economy of its gasoline-powered version. Nissan also announced that the Nissan Infiniti/Fuga Hybrid, together with the Nissan Leaf, will include its new Vehicle Sound for Pedestrians system to alert pedestrians, the blind and others to their presence when the hybrid is operating at low speeds in all-electric mode.
  The hybrid includes one electric motor and two clutches to allow the 3.5L V6 (302 hp (225 kW) and 258 lb⋅ft (350 N⋅m)) gas engine and electric motor to drive the rear wheels simultaneously. The lithium-ion battery pack will come from the Infiniti Essence. The VQ35HR 3.5 L V6 Hybrid utilizes the Atkinson cycle. The electric motor, installed in parallel between the engine and the transmission, produces 68 PS (50 kW; 67 bhp) from 1.3kWh lithium-ion batteries that are expected to have a service life of 10 years. The batteries are installed upright behind the rear seats. The main sacrifices are that the luggage compartment space is reduced, the hybrid's rear seats are fixed in place and cannot fold down, and all-wheel drive is not available. One benefit of the battery placement though, is that it leaves the hybrid with a 51/49 front to rear weight distribution.
  The combined power output of the M35H's hybrid power-train is 360 hp (268 kW; 365 PS) at 6500 rpm, and an estimated 391 lb⋅ft (530 N⋅m) of torque at 2000 rpm.
  Reviewers have considered the 2012 Infiniti M35h, along with the 2011 Porsche Panamera S Hybrid which also debuted in the same calendar year, as among the best executed hybrid performance luxury cars. The M35h and Panamera S Hybrid are the first hybrid gasoline-electric vehicles with an automatic transmission to return frugal fuel economy figures and retain the acceleration/handling characteristics of its gasoline-only counterparts. Earlier hybrids such as the Lexus 2007 GS 450h used a CVT for fuel economy at the cost of driving dynamics, while the 2010 BMW ActiveHybrid 7 which has an automatic transmission did not feature significantly improved mileage over its gasoline counterpart. The M35h's fuel economy is superior to the M37, and it is almost as fast as the M56 while providing a more balanced, near 50/50, front/rear weight distribution.
  On August 23, 2011, the Infiniti M35h set an official Guinness world record for the world's fastest accelerating production full hybrid. The feat took place at the United Kingdom's Santa Pod Raceway, where CAR magazine journalist Tim Pollard drove the vehicle down the quarter-mile dragstrip in 13.896 seconds. The M35h averaged 13.9031 seconds for all runs, reaching speeds over 100 mph. Guinness adjudicators were present to witness the run and certify the record. The official claimed 0-100 km/h (62 mph) time for the Infiniti M35h is 5.5 seconds.
