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 Integra to capstone combustion era as EV transition begins

The recent launch of the resurrected Integra nameplate is just part of a larger shift in mission at Acura. Its leaders have repeatedly said they want Acura to be the performance brand of Honda, where driving fun and dynamics come first. However, in a new report, Acura says it plans to go big on fully electric vehicles, at even greater speed than its parent company, by skipping the hybrid step altogether. According to Acura assistant VP of sales Emile Korkor, the Integra was a capstone to the internal combustion era at Acura. It marked a sort of homecoming to the marque's performance pedigree, and once Integra is launched, the brand will move forward with electrifying its lineup. The company's plans were revealed in an Automotive News interview, where Korkor said, "We're going to bypass hybrids altogether. So our shift is going very rapidly into BEV. That's our main focus." At first blush, that seems to be at odds with brand boss Jon Ikeda's public statements about Acura. As recently as a couple of weeks ago, Ikeda was saying that he wanted to take the Integra racing, as something of a mascot for the "fun" brand at Honda. Perhaps we've been desensitized to automakers making big proclamations about EV transitions a la Jaguar, Land Rover, Bentley, and Infiniti, but typically the green messaging has not been about performance in the traditional sense. Says Korkor, "We're not just dipping our toe in the water with electric at Acura, we are jumping all in. And that's not just because we need to. It's because we want to. Acura is really focused on performance, and electrification is one of the greatest ways we can augment that performance." While electrification and performance are not mutually exclusive, we have yet to drive an EV that connects to the road as beautifully as a 1990s Integra or NSX did. Acuras have never been about power and torque. Yet they were still compelling performance cars thanks to brilliant steering and driving dynamics. Then there's the issue of what Acura represents. Back in February, Ikeda said that Acura was purposefully holding off on an EV strategy because it needed to re-establish its performance bona fides. Now, Korkor says, "The benefit of returning to the Integra right now is that it's going to help shepherd a new generation of customers and build loyalty as we move into a new era." The problem is, the Integra alone isn't enough to establish that performance cred.

Acura announces NSX GT3 Evo22 race car will live on

The Acura NSX may be winding down production in 2022, but it still has some life left on the track. Today, Acura announced that it will introduce a new version of its NSX GT3 race car. It features a slew of improvements that should make the platform more competitive. Called the NSX GT3 Evo22, it builds upon the existing NSX GT3 a car that has won multiple championships in IMSA, SRO and Japan's SuperGT. The Evo22 gets improved intercoolers for the 3.5-liter twin-turbo shared with the road car, allowing it to perform consistently in a wider range of conditions and locations. Underneath, the suspension earns some tweaks in revised spring rates and geometry adjustments. To improve the car for endurance racing, the Evo22 reduces pit time with larger fluid tanks, while a revised wheel system allows for quicker tire changes. An FIA-mandated rain light illuminates the rear. Acura will also offer several air conditioning and headlight options. As with the outgoing NSX GT3, the Evo22 eschews the road car's hybrid and all-wheel-drive systems. Instead, it employs an XTRAC semi-automatic six-speed sequential transmission to send power to the rear wheels. Both the race and road car, however, share the same specs for the engine block, heads, valvetrain, crankshaft, pistons, and dry-sump lubrication system. The motors and chassis are both built at Acura's Performance Manufacturing Center in Ohio, while final assembly for the GT3 takes place in Milan, Italy. While European GT3s are supported from Italy, Honda Performance Division in Southern California will support North American teams. The NSX GT3 is the defending IMSA GTD and SRO GT Manufacturers’ Champion, and has achieved 25 IMSA and SRO class wins since its North American introduction in 2017. Interestingly, Acura says the the NSX GT3 is homologated globally through 2024. So, while new road cars won't be produced after next year, you'll still see them representing the "A" calipers at the track beyond that.
