The stretched model adds 5.9 inches to the M's standard wheelbase, which Infiniti says "enhances roominess for passengers sitting in the rear."ť However, the Japanese automaker didn't reveal by how much rear seat legroom has improved.
Buyers looking for a long-wheelbase M will have two models to choose from - the M35hL and the M25L.
The M35hL, as the name implies, is essentially a long-wheelbase version of the standard M hybrid. Like the M35h, the M35hL is powered by a 3.5L V6 paired to an electric motor, but power has apparently been enhanced for the Chinese market. Whereas the U.S.-spec M35h delivers a combined 360 horsepower, Infiniti says the M35hL generates 427 horsepower. Torque remains unchanged with a combined total of 457 lb-ft.
The M25L receives its motivation from a 2.5L V6. The M25L's performance promises to be leisurely with just 232 horsepower and 187 lb-ft of torque on tap, but should offer a much lower price point than the M35hL.
Infiniti hasn't revealed any plans to sell a long-wheelbase version of the M in any other global markets.
