New TLX A-Spec leads Acura's three-car Pike's Peak attack

Once again, Acura is headed to Pikes Peak for the hillclimb on June 25 with a small group of machines. This year the focus is on the TLX, with two vehicles bearing the sedan's name and shape. The two cars are very different, though, and will compete in two different classes. The first is the TLX A-Spec. This started life as a production TLX, but the 3.5-liter V6 has been reworked with pistons, rods, camshafts, and a valvetrain from Acura's TLX GT race car. The engine also has a turbocharger, which helps the V6 make an impressive 500 horsepower. All those ponies go to the front wheels through a limited-slip differential. In addition to the powertrain upgrades, the interior has been gutted, and a big wing and front splitter fitted. The A-Spec will compete in the Pikes Peak exhibition class. The other TLX is a TLX GT. This is the type of car from which the A-Spec borrows engine components, but not the TLX GT's twin-turbocharger system. TLX GTs have already been competing in motorsports, specifically in the Pirelli World Challenge. Acura did make some changes to this car for Pikes Peak, though. The suspension and engine computer have been tweaked, gear ratios shortened, and additional aerodynamic bits added for more downforce. The TLX GT will compete in the open class. Despite the focus on the TLX, Acura is still bringing an NSX to the hill climb. This car is similar to the one that raced in the Time Attack 1 class last year, but has some changes for the Time Attack 2 class. Most notable of these changes are the massive rear wing and front splitter. According to Acura, these aerodynamic aids were based on those used for the NSX GT3 race car. Acura also reduced weight, changed the tuning on the engine computer, and fitted sticky R-compound tires.

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.

Acura TLX caught naked in production guise, can you spot the differences?

Acura doesn't tend to do concept cars these days that don't foreshadow a specific upcoming production model. The ZDX prototype of 2010 previewed the production version, as did the ILX and RLX showcars of 2012 and the MDX of 2013. The NSX concept is on its way to production, as the SUV-X concept is likely to do as well in the coming years. So when Acura revealed the TLX prototype at the Detroit Auto Show a few months ago, we all but knew it would only be a matter of time before that, too, would be produced. And here it is.
Spied all but completely undisguised while undergoing testing, this pair of TLX prototypes (one in white, one in black) looks almost identical to the show car. You might spot a few minor tweaks here and there - the strip of LEDs in the lower front bumper have been replaced by round fog lamps and some of the chrome accents are missing - but by and large, we're looking at the same vehicle we saw in Detroit earlier this year.
The finished production version of the TLX is expected to debut at the New York Auto Show next month, after which it will replace both the TSX and the TL, slotting in between the smaller ILX and the larger RLX in Acura's sedan lineup.
