Hondata's 2019 Acura RDX tune brings the mid-range torque

One of the big advantages to the era of turbo Hondas is that there's plenty of horsepower and torque left on the table for tuners to take advantage of. One of those companies is Hondata, and following its upgrades for the Civic and Accord, it's now tuning the Acura RDX luxury crossover. The RDX uses a turbocharged 2.0-liter engine similar to those in the Accord and the Civic Type R. In stock form, it makes 272 horsepower and 280 pound-feet of torque. With Hondata's Stage 1 tune, the company says that horsepower increases by about 10 across the rev band. Looking at the dyno graph, it also appears that peak horsepower increases by about 5 horsepower, and peak torque is up by about 15 pound-feet. Peak torque also appears to arrive sooner, and most of the torque curve seems to be up by 10 to 15 pound-feet. The increases in power and torque are available in all four of the RDX's drive modes. The Stage 2 tune increases power torque even more in Sport and Sport+ modes, and keeps Snow and Comfort modes at Stage 1 settings. Peak horsepower looks to be up about 10 over stock, but the mid-range sees as much as a 28-hp increase. Peak torque sees a huge jump of about 45 lb-ft over stock based on the dyno chart, and it's available even lower than the Stage 1's peak torque. If this all sounds good to you, you can order up a Hondata FlashPro computer for your RDX right now. It costs $695 and comes with the handheld computer for uploading or removing tunes. RDX owners in California should note that neither tune is currently CARB legal. Related Video:

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.

We drive the Acura TLX-GT racecar

Don't break the car. As you can tell from the video, that's the theme of the day at Gingerman Raceway in South Haven, MI. After two short lapping sessions in the Acura TLX-GT fear gave way to familiarity, and a second theme emerged: this is awesome. The anxiety was appropriate. There are only two TLX-GTs in the world, and both were at Gingerman that day. A mishap would potentially put either Ryan Eversly and Peter Cunningham out of contention for the subsequent Pirelli World Challenge race. I did not want to be that guy. But back to the awesome part. The TLX-GT is barely TLX, but more Acura that you might expect. The wheelbase, roof, and doors are all stock dimensions, although all the bodywork is carbon fiber. Out go the front MacPherson struts, in goes a special double-wishbone suspension. All-wheel drive comes from an XTRAC six-speed sequential transmission originally developed for Dakar Rally vehicles. The side mirrors are stock. Under the hood lies a 3.5-liter twin-turbo V6 with a stock block, head, crank, and throttle body. "Under the hood" is a generous term, though, because half of the engine sits inside the cabin. The front end of the block is aft of the front axle - the rest of the hood is taken up with radiators and hoses. To service the turbochargers, the RealTime mechanics remove the top of the dashboard. The front-mid engine location pushes the driver's seat back to the B-pillar, so you sit like Hightower from Police Academy. Only with less visibility. This does not calm the nerves. Nor does the din of 600 or so unmuffled horsepower. My first laps were understandably timid. But the TLX-GT is actually easy to drive. You get used to the low, rearward seating position almost immediately. Once rolling you don't need the clutch for shifts - just bang the right and left paddles to go up and down. I even became accustomed to the acceleration. At more than 3,000 pounds curb weigh the TLX-GT is quick, but not as explosive as cars like the Chevrolet Corvette Z06. Where the TLX-GT blows away road cars is in grip and braking, neither of which I fully exploited. The brake pedal is so hard you feel like you're standing on it just to get the pads to bite. Once engaged, they're like an endless well of deceleration, with ABS somewhere down at the bottom of the abyss. Second lapping session over, car returned intact and adrenaline high in full effect. I had the uncontrollable urge to get back behind the wheel. I mean, I barely had time to get up to speed.
