TLX: The redesigned 2015 TLX mid-sized sedan, unveiled at the 2014 New York auto show, will replace the TL and TSX sedans in the U.S. lineup. The TLX shares a 2.4-liter base engine with the Honda Accord, but the TLX's mill has higher compression ratios, a two-stage intake and a modified exhaust. The base TLX engine generates 206 hp. It's 1.5 seconds quicker in 0 to 60 mph than the outgoing TSX. The TLX's 290-hp, 3.5-liter V-6 engine is shared with the MDX and RLX and gets 5 mpg better highway fuel economy than the outgoing TL. Both the four- and six-cylinder cars will have standard four-wheel steering; the V-6 has optional Super Handling All-Wheel Drive, or SH-AWD. It goes on sale this fall, with pricing expected to be released closer to launch.
RLX: Redesigned in summer 2013. A hybrid version of the sedan was to arrive in dealerships this spring but has been delayed until late 2014.
NSX: Acura's sports car will be as much about technology as performance when it arrives in the first half of 2015. Instead of a monster engine, the NSX will have a compact, direct-injection V-6 combined with a lithium ion battery pack for power. The Sport Hybrid SH-AWD system uses two integrated drive units at the rear wheels connected to a motor-generator that delivers power. Regenerative brakes will capture electricity and then deliver torque to the outside wheel -- while absorbing negative torque from the inside wheel -- as the car goes through a corner. Development issues with the new-generation hybrid may delay the launch.
RDX: Redesigned in spring 2012. Expect the next version of the crossover in calendar 2018, with a midcycle change in spring 2015.
MDX: Redesigned in summer 2013. Expect the next version in calendar 2019, with a midcycle change in mid-2016.
