Honda sending two NSX racers and new EV concept to Pikes Peak

Honda is always good for a few interesting Pikes Peak entries. In 2015, Acura supplied a 2017 NSX prototype for pace-car duty. This time around, two NSXes will compete alongside a reconfigured version of the company's four-motor electric racecar. Those aren't the 2016 entries above. The one on the right is last year's pace car and the one on the left is a first-gen NSX that did the hillclimb the past few years. The 2016 cars haven't been unveiled yet, but we know that one will be in the Time Attack 2 Production class, which is mostly stock with the addition of items like a roll cage, and the other will be in Time Attack 1. TA 1 allows modifications to the powertrain, additional aero aids, suspension changes, and other tweaks, so expect to see a lot more power and a big wing on the back. The cars will be driven by James and Nick Robinson, brothers who work for Honda R&D in Ohio. Honda will use a version of the four-motor electric powertrain from its 2015 CR-Z Exhibition class entry in a new EV. (We got to drive a non-race tune of this setup in Japan last year.) The 2016 version, which will wear a different body, moves to the Electric - Electric Modified class of last year's frontrunners. We're told this car is aiming for an overall win at the 2016 race; the CR-Z took 11th place overall in 2015. The EV will again be driven by Tetsuya Yamano, a Japanese Super GT driver. Oh, and there will of course be a factory entry or two from Honda's Powersports division. Honda engineer Keith Steidl will ride a 2015 TRX1000 ATV in the Pikes Peak Challenge - Exhibition Powersport class. In the past, Honda has fielded plenty of other neat stuff in the Race to the Clouds. In 2012, it ran an NSX fitted with a twin-turbo V6 from an LMP2 car, and the 2013 race saw the very practical 532-horsepower turbocharged Odyssey minivan join the Exhibition class. The 2016 race marks the Pikes Peak hillclimb's 100th anniversary (but not the 101st running since competition took some breaks back in wartime). We're looking forward to June already.

Honda recalls 2.7 million vehicles for new air bag inflator defect

WASHINGTON — Honda said on Tuesday it will recall 2.7 million older U.S. vehicles in North America for potentially defective air bag inflators. The defect involves a different type of Takata inflator than those that have prompted the largest-ever auto safety recalls worldwide covering more than 42 million U.S. vehicles by 19 automakers with Takata air bag inflators. The new recall covers Honda and Acura automobiles from the 1996 through 2003 model years. Honda said it is aware of one field rupture of an inflator in the new recall campaign — a 2012 crash in Texas that resulted in an injury — and two in junkyards in Japan. The campaign covers 2.4 million U.S. vehicles and 300,000 in Canada, Honda said, adding that it has not determined recall numbers for other countries. Takata issued a new defect notice in November for inflators from four automakers, including Honda. Honda said all three vehicles "potentially were exposed to unusually high amounts of moisture prior to the rupture events." Honda said the recalls cover driver front airbag inflators manufactured with non-azide propellant and said "all inspections and repairs will begin in approximately one year, as replacement parts from alternative suppliers are not yet available." Honda said it "regrets any inconvenience or distress that this situation may cause to our customers as we seek to resolve this situation. Honda believes that the risk of improper airbag deployment in its vehicles remains very low at this time, but we cannot absolutely guarantee the performance of any recalled part." Related Video:

A smoother operator | 2017 Acura MDX Sport Hybrid First Drive

There's a lot to unpack when trying to understand the 2017 Acura MDX Sport Hybrid. Acura is billing it as a three-row crossover infused with NSX technology via a sport-oriented hybrid drivetrain. So it's a hybrid crossover, sure. But it doesn't comport itself like a traditional crossover, nor is it a conventional hybrid. What it is, underneath, is an intentionally subtle blend of impressive technologies doing their best to appear transparent – and it's too subtle, I fear, to be appreciated by those who'd like it the most. This is a lot of foreshadowing, but if you're not familiar with the MDX Sport Hybrid's powertrain, let's fill you in. The MDX Sport Hybrid uses the same basic system as the 2014 RLX Sport Hybrid, with some newer NSX battery tech sprinkled in, packaged neatly into the refreshed third-generation MDX platform. The system improves handling and efficiency – but more important, it smoothes out the harshness of shifts and engine stop-starts. We do need to examine the system in some detail to understand how all this affects the MDX as a whole, so let's go toe to tail. Up front is a transversely-mounted 3.0-liter V6 making 257 horsepower and 218 pound-feet of torque, as well as featuring i-VTEC and cylinder deactivation. It's slightly smaller than the 3.5-liter V6 found in the conventional MDX and many other Honda and Acura products. Attached alongside is a Honda-produced 7-speed dual-clutch transmission that has a 47 hp, 109 lb-ft electric motor-generator stuffed inside. Amidships are the battery pack and the electronics to control it, and stretching aft from there are large cables feeding power to a pair of electric motors that reside in single housing, one for each wheel. Together, they produce electron witchcraft and torque-delivery wizardry – and add 72 hp and 108 lb-ft of torque to the mix. The total system output is 321 hp and 289 lb-ft of torque – a gain of 31 hp and 22 lb-ft over the conventional MDX SH-AWD. Beyond the raw numbers, there's the remarkable subjective benefit of the Sport Hybrid's drivetrain. Engine start-stop events are quiet and smooth, nearly imperceptible when under way – in stark contrast to the too-perceptible shudder of competing engines kicking on. The electric motors (mainly the one residing in the transmission) add in power to make up for the lull during a shift, making shifts up or down seamless, as well as providing regenerative capacity.
