Infiniti is swapping alphanumeric model designations across its lineup — all cars now have a Q prefix and all SUVs a QX prefix. That means the sedans formerly known as the M37, M56 and M35h — or collectively simply as M — are now lumped under the Q70 moniker. Competitors include the BMW 5 Series, Lexus GS and Audi A6.
On the new lineup card, the M37 is now the Q70 3.7 and the M56 is the Q70 5.6, and both are available with rear- or all-wheel drive. The M35h is now the Q70 Hybrid and is available only with rear-wheel drive.

Q70 Hybrid Formerly known as the M35h, Infiniti’s first hybrid sedan is rebadged as the Q70 Hybrid for 2014 and returns with a 3.5-liter V-6 engine, a 50-kilowatt electric motor and a lithium-ion battery pack behind the rear seat. The engine and motor combine for 360 hp, and power is delivered to the rear wheels through a seven-speed automatic transmission. Like other Q70 models, the Hybrid requires premium gas.
Q70 Hybrid can drive on electric power alone up to 62 mph and as far as 1.2 miles, according to Infiniti
