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's early sales results look promising

Acura made a bold move earlier this year when it decided to axe two fairly popular models in the TL and TSX and replaced them with a single sedan: the TLX. After all, how often have you seen modern automakers consolidating vehicles in the lineup? But early indications have shown that the gamble might have paid off, at least so far, because the TLX has been outselling its predecessors for its first months on sale.
Acura has only released TLX sales numbers so far for August and September, but the results have been promising. In August, the company moved 2,286 of the new sedans, beating last year's figures for the same month from both the TL at 2,227 sold and the TSX at 1,755. Then in September, the newcomer did even better with 3,884 units leaving dealers to surpass the two previous vehicles combined from their 2013 monthly stats.
According to The Truth About Cars, the TLX's September numbers were even more impressive when looking even deeper into Acura sales history. It claims that you would have to go back to March 2011 when the TL sold 3,995 units to have seen it beat the new TLX. And the TSX hasn't surpassed the latest model's figure since December 2010.

Daily Driver: 2015 Acura TLX

Today's Daily Driver features the 2015 Acura TLX, reviewed by Seyth Miersma. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. Show full video transcript text Hey all, this is Seyth with Autoblog and I'm here in the 2015 Acura TLX. Right off the bat I can tell that the TLX doesn't feel anything like as sporting a sedan as the TL it replaced, at least not in the versions that I last drove, which admittedly were TL's with V6 power and the SH all wheel drive. This TLX has got a 2.4-liter, four-cylinder engine, it's making 206 horsepower, and 182 pound-feet of torque, and it is connected up to a eight-speed, dual-clutch transmission. As you can tell by the power output this isn't an impressively fast car. It weighs about 3,500 pounds so it's lugging around some weight. At the same time the eight-speed transmission is really responsive especially as you go through the selectable gear programs, you can make the throttle response pretty good. It is a throttle by wire as well and I haven't noticed any weirdness there, it feels very linear, and like I said, when I turned the system into the sport plus mode the gas pedal becomes really responsive. The exhaust note is muted, you really have to get up over 5,000 rpm before you start feeling like the engine is really pushing you. One of the things that struck me first about this Acura when I got in it was how quiet it was at speed. I feel like in the luxury segment, Acuras have historically done a little bit better for being sportier versions of cars in their segment and not necessarily more refined, but that seems to have been changing a lot on the last few generations of Acura. What it lacks in athletic ability it makes up for in composure. I'm on a pretty good right now, there are plenty of bad ones around where I live so this suspension soaks up a lot of the impacts and it dampens the sound of them as well too. Acura is clearly going after a much more mainstream customer these days and I think a car like this could be very attractive, more attractive than ever for a shopper of something like a Lexus ES. One feature I did play around with was Acura's active lane keep assist which works actually by moving the steering wheel to a degree to keep you centered in your lane if your hands are off the wheel.
