Continuing Honda’s drive to surgically implant a big shiny corporate “shield” grille on all their Acura models, the midsized MDX crossover has received a mild facelift for the 2010 model year, alongside the smaller RDX crossover.

Changes also include some minor engine tweaks, a new 6-speed automatic transmission, chassis refinements and improved look and feel of interior trim materials plus the addition of new technology features.

On the outside, the 7-seater MDX gains Acura’s new corporate grille, redone front and rear bumpers, new exhaust tips, revised hood, new side sills and reworked taillights with brighter LEDs. The available 19-inch seven-spoke alloy wheels complete the exterior upgrades.

Moving on to the interior, Acura says that the 2010 MDX benefits from higher quality trim materials, a thicker steering wheel grip, increased use of LED interior lighting and revised cockpit controls along with relocated front seat headrests for improved comfort and more detailed leather stitching.

Furthermore, Acura has introduced several new technology features on the RDX such as the AcuraLink Real-Time Weather and Traffic Rerouting systems, a new full VGA 8-inch navigation screen, an upgraded rear view camera with three unique view choices and updated audio and rear entertainment systems.

Under the hood, the 2010 model year MDX receives an updated version of Acura’s 3.7L VTEC V6 engine linked to an all-new 6-speed automatic transmission. Among other changes, the V6 features cylinder heads with improved cooling, new intake valve springs, a new EGR system, unique long-reach spark plugs, a larger throttle body. The revised engine produces the same output as before at 300 hp and 270 lb-ft, which is actually 5 lb-ft less torque than before.

However, in combination with the new transmission, the 2010 MDX returns an EPA estimated city/highway fuel mileage of 16/21 mpg which is an improvement of 1 mpg city and 1 mpg highway over the 2009 model.

Finally, Acura says that the MDX’s ride and handling have been improved thanks to the revised power steering system, stiffer rear trailing arm mounting and better body rigidity.

The Acura 2010 MDX is expected to go on sale in the U.S. sometime in September this year.
