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.

Acura TLX GT Racecar bringing the 'X factor' to Pirelli World Challenge

One doesn't normally think of Acura offering anything to mix it up with the SRT Viper, Lamborghini Gallardo, Mercedes-Benz SLS AMG, Nissan GT-R, Audi R8 and Ferrari 458 Italia (at least while the NSX is still off in the ether), but that's exactly what's about to happen. Honda's premium outpost is jumping into the top tier of the Pirelli World Challenge with this 2015 TLX GT.
The surprise reveal of this racecar at today's Detroit Auto Show will be campaigned by RealTime Racing, no stranger to racing Acuras, in the GT class (previously, the team had campaigned the series a rung down in GT-S).
The racecar is powered by a twin-turbo variant of the direct-injected V6 to be found in the production TLX sedan, right along with its Super-Handling All-Wheel Drive system. There's no word on how much power this HPD-massaged engine will put out in race trim, but we won't have to wait long to hear it fire up - the car is set to take to the track with team owner Peter Cunningham at the wheel in the next few weeks.

The 2017 Acura NSX will cost $156,000

Back in October, when our Editor-in-Chief Mike Austin drove the 2017 Acura NSX for the first time in the Bay Area and at Sonoma Raceway, we guessed that the hybrid supercar would start at around the $170,000 price point. We weren't that far off – it starts at $156,000, and tops out around $205,000. But now that we have a solid sense of what Acura thinks this car is worth, and we know what they benchmarked the NSX against, we can compare apples to apples. Let's be clear: we like this car. Austin described it as "makes you giggle" fast, everyday-comfortable, and chock full of impressive party tricks like seamless shifting – with only a few foibles, like numb steering, to spoil the illusion of perfection. Back to the benchmarked cars. Acura says the NSX will compete with the Audi R8, and was developed to compete with the now-superseded 458 Italia. Let's start with the 2017 R8 V10 Plus – pricing hasn't been released, and a direct Euro-to-USD conversion isn't the whole story, but it starts at the equivalent of $179,000 in Europe. For that, the R8 V10 Plus provides 610 horsepower, a seven-speed DCT, and a 3.2-second sprint to 60 mph. The 458's successor, the 488 GTB, should be more expensive than the $243,000 the old model started at, and provides 661 hp, a seven-speed dual-clutch, and a 0-60 time of around three seconds (official numbers haven't been released for acceleration). For less money than either of these cars, the NSX delivers ... less. Total system output is 573 hp. It has a slight edge in gear count, at nine speeds, and should beat the R8 to 60 mph. But there's no V10, let alone Ferrari's feral turbocharged V8. It'll be up to buyers to determine if the compromises involved are worth a few thousand dollars in savings, if no options are selected. It should also be noted that Acura describes this as its first "built-to-order" vehicle, but the limited external color options and interior schemes don't appear to be much different than the extent to which you can customize an Accord. The configurator goes live on February 25th, if you want to see for yourself. Lastly, in what now seems to be a necessary part of a new high-end car launch, Acura will auction off VIN 001, the first production NSX, at Barrett-Jackson in January. All proceeds from that auction will benefit two charities: the Pediatric Brain Tumor Foundation and Camp Southern Ground.
