2019 Acura RDX crossover gets turbocharged power, A-Spec version

NEW YORK — Calling the RDX that Acura showed at this year's Detroit Auto Show a "concept" was stretching that term to the limits of credulity. The production version of the 2019 RDX is here, and this turbocharged crossover with available AWD looks darn near identical. While it offers all-wheel drive like its Lexus NX and Audi Q3 competitors, Acura's next-generation SH-AWD should be a serious selling point. Let's cover that "Super Handling All-Wheel Drive" system for a moment. It takes power from the 2.0-liter, 272 horsepower and 280 pound-feet of torque engine and routes it up to 70 percent rearward, and there's real torque vectoring (rather than brake-based faux vectoring) to shift 100 percent of that rear axle power to either wheel. The broad strokes are similar to the outgoing model's system, but there's much more available rear power bias — in the 2016 model, up to 40 percent could be sent to the rear. And that was up from 25 percent for pre-2016 models. The takeaway is that the RDX should handle a lot better on both dry and slippery pavement, and feel a bit sportier doing it. A new engine may help as well. The outgoing 3.5-liter V6 is replaced by a turbocharged four-cylinder, almost certainly related to the unit in the Accord and Civic Type R, and tuned somewhere in between those cars (252 and 306 horsepower, respectively). We expect the new engine to be lighter than the old V6, and less weight off the front end should improve steering feel and handling. For those keeping track, the new engine is down 7 horsepower but up 28 pound-feet in torque, and thanks to turbocharging the torque band starts down low and is relatively flat, so more oomph from a stop and on through the rev range. The six-speed automatic is gone, replaced by a 10-speed automatic. Most of its competitors use six- or eight-speed units, so that'll be a marketing focus. As you'd expect, the individual ratios are closer-spaced but the total ratio spread is, according to Acura, 62 percent wider than the outgoing automatic. There are steering-wheel-mounted paddles if you'd like to shift yourself. Since the styling is very much a lightly retouched Prototype RDX from the Detroit show, it's nice to be able to give a sense of the new car's proportions with hard numbers. First of all, it's riding on a 2.6-inch longer wheelbase. Overall length is 187 inches, up from 184.4, and width is unspecified.

Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.

Top 10 small cars with the longest total driving range

Editor's Note: Since this article was originally posted in the spring of 2015, much has changed in the automotive landscape, especially among those shopping for small car economy. With thanks to Volkswagen for their blatant cheating – and subsequent cover-up – on diesel emissions, the largest player in the diesel passenger car segment isn't playing – they're paying; billions are going for both car buybacks and federally-imposed penalties. And for a few VW execs there exists the very real possibility of jail. With the absence of a big player and the abrupt entrance – via Chevy's new Bolt – of an affordable EV with 200+ miles of range, we've limited the diesel listings to Jaguar's new XE. And for those wanting an updated look at efficiency and range, Autoblog has it – or the EPA has it. Long before electric vehicles were part of the mainstream conversation, car lovers and skinflints alike would boast about the total range of their vehicles. There's something about getting farther down the road on one tank of gas that inflames the competitive spirit, almost as much as horsepower output or top speed. Of course, the vehicles with the very best range on today's market are almost all big trucks and SUVs; virtually all have the ability to carry massive reserves of fuel. Top up a standard Chevy Suburban and you can expect to travel almost 700 miles (you'll need to stop before the Suburban stops...), while a diesel-fed Jeep Grand Cherokee manages almost as many. But what about vehicles that are smaller? The EPA has, essentially, three classifications for 'small' vehicles: Minicompact, Subcompact and Compact. All three are measured based on interior volume, meaning that some cars with rather large exterior dimensions and engines slot in next to traditional small cars. But even though impressive GT coupes from Porsche, Bentley and Mercedes-Benz may have much larger gas tanks to feed their powerful engines, that capacity is offset by higher rates of consumption... in most cases. We used the EPA's Fuel Economy Guide for model year 2017 cars as a start, calculating the official highway miles per gallon rating with each vehicle's tank capacity. The resulting numbers aren't necessarily real world, but they do offer a spectrum for total theoretical range. The eventual top ten surprised me on a few occasions, and comprised quite a varied list of vehicles. 10.
