2014 Acura RLX Advance Beauty Right Done Small

‘ADDING THE X FACTOR’

The all-new 2014 Acura RLX with the Advance Package adds more power, performance, comfort, luxury, high-tech connectivity and safety systems that take this all-new ‘top-of-the-line’ Acura into a higher position competing against the best mid-size luxury sport sedans on the market.

The all-new Acura is the most powerful, spacious and technologically advanced Acura sedan ever.  It is powered by an all-new 3.5 liter SOHC Earth Dreams Technology V6 engine featuring an aluminum block/heads, direct injection, and intelligent VVT + Lift electronic control, four-valves per cylinder, generating a healthy 310hp at 6,500rpm and 272lb. ft. of torque at 4,500rpm.  It also features variable cylinder management cylinder deactivation system that improves mpg when cruising.  This advanced engine is mated to a re-engineered, six-speed automatic FWD transaxle with sequential Sportshift paddle shifter on the steering wheel including a Sport mode to remap for faster and higher rpm gear changes and tighten the dampers for more spirited handling.  The new Grade Logic Control works with the transmission to keep it in the proper gear when driving up or down hilly terrain.

The state-of-the-art fully independent suspension gives you an amazing ride of a sport sedan and a luxury sedan all rolled into one.  Up front is a double-wishbone, lower double-joint setup with telescopic gas-filled Amplitude Reactive shocks and a 33mm solid stabilizer bar.  A multi-link rear suspension setup also features the telescopic gas-filled Amplitude Reactive shocks and a 25mm solid stabilizer bar to keep the RLX flat when attacking steep curving roads.  It is tremendously responsive and flattens out the potholes on rough roads.  Giving me an even more responsive feedback from my steering inputs is the electric power rack & pinion steering system that features Acura’s Precision All-Wheel Steer (P-AWS) that continuously monitors and calculates the correct amount of independent rear-wheel steering (toe angle) necessary to help you maneuver through tough curving roads with ease and stability.  With these innovative systems and Acura’s Vehicle Stability Assist with Traction Control, there is no hint that the all-new RLX is a front-wheel-drive sedan.  I felt no hint of ‘torque steer’, no understeer with the P-AWS system.  Steering is quick and responsive with a ratio of 13.9:1 and just 2.58 turns lock-to-lock.  You can shut down the Traction Control system to let the rear slide out a little at the apex of the curve to got my pulse running higher.

Quickly and safely slowing the all-new RLX down from speed are big, powerful brakes.  Up front are 12.3 inch vented discs clamped with large, Acura lettered single-piston calipers.  The rear features 12.2 inch solid discs also clamped with large single-piston calipers.  Keeping control of the RLX during hard braking on wet or slick pavement are standard ABS, EBD and BA systems.

2013 Acura MDX AWD Review & Test Drive

2013 Acura MDX Beauty Right Done Small

‘HIGH PERFORMANCE MEETS LUXURY, COMFORT AND CONNECTIVITY’

First introduced in 2001 and winner of Motor Trend Magazine’s ‘Sport Utility of the Year’ award, it was last refreshed in 2010 with the addition of the Acura signature ‘over-bite’ grille and a powertrain upgrade with the 300hp 3.7 liter SOHC V6 engine mated to a six-speed automatic with paddle shifting.  The 2013 model that I tested is long overdue for a totally new look and Acura promises that to happen in the 2014 model year.  In the meantime, this MDX Advance and Technology edition maintains the core elements that make this SUV so enticing and exciting to drive-the 300hp V6 engine with sequential shifting paddles on the steering wheel, a Nurburgring tuned fully independent suspension with comfort and sport settings, Acura’s Super Handling All-Wheel Drive (SH-AWD) system, Acura’s ‘ACE’ body structure, a luxurious interior with room for seven passengers and a load of advanced features including Acura’s Navigation System, with voice recognition, an awesome 10-speaker Acura/ELS surround sound system, a power liftgate and a rearview camera.  These and a host of other features are standard and make the MDX one of the best high-performing luxury sport utility vehicles on the market.  It leaves out nothing except for a Smart Access Key Fob and push button start/stop which isn’t the end of the world, but standard on most high-end sport utility vehicles-they will probably be available in the all-new 2014 edition.

Other than those two tidbits, the 2013 Acura MDX is awesome as I enjoyed every minute behind the wheel in city and highway driving.

A generous 300 horsepower and 270lb.ft. of torque is generated by the 3.7 liter, SOHC, 24-valve, all-aluminum V6 with VVT & Lift Electronic Control (VTEC).  It gives the 300 horses a wide power band at the low end for quick launches and gas-saving low rpm when cruising down the highway.  The smooth shifting and sport-minded sequential sportshift six-speed automatic transmission has paddle shifter on the steering wheel, Grade Logic Control, shift hold control, cornering G shift control and hill start assist.  Whether driving up or down on pavement or off-road, this transmission enhances your capabilities by adding extra control of your speed and handling.  Speaking of handling, the super handling all-wheel drive (SH-AWD) system is fantastic-super quick changing torque to each wheel as needed when driving on wet or slick pavement and when off-roading to your favorite destination.  The center of the instrument cluster shows you the torque bias at all four wheels as it is happening as you drive.  It is seamless so you don’t know that the system is assisting you when on the road or off-road.  The torque-sensing power-assisted rack & pinion steering system is quick acting to your inputs with great feel for the road and on-center when driving straight-ahead at speed.  The drive is solid as a rock further enhanced with the big footprint of …read more
