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.

Acura TLX Type S vs. BMW M340i xDrive | Sport sedan comparison test

Luxury sport sedans are still turning up on the market, and the Acura TLX Type S is one of the freshest cuts of meat in the window. It’s AcuraÂ’s big return to Type S performance models. Benchmarked against the proverbial best performance sedans of the segment, Acura is aiming to not just to compete, but to win dogfights like these. To see if the return of Type S is all itÂ’s cracked up to be, we decided to pin it up against the historical king of sport sedan shootouts: a BMW 3 Series. Specifically, the Type S is taking on the M340i xDrive, which is this AcuraÂ’s most natural competitor from Munich. Should the diehard BMW driver make the switch to Japanese performance? Does Type S do enough to lift this Acura up to best GermanyÂ’s finest? There are a lot of variables at play here, and they all make it complicated to choose a winner. The similarities between these two begin from the top of the spec sheet and go down. Both have 3.0-liter turbocharged six-cylinder engines — BMW arranges its cylinders inline, while Acura chooses a V configuration. Quick-shifting automatic transmissions are standard. BMW uses an eight-speed unit, while Acura uses a 10-speed. Both get electronically-controlled dampers, big brakes and sticky summer rubber. They each offer up usable backseat space and reasonably-sized trunks. WeÂ’d feel just as confident showing up to an important business meeting in either one as we would at a track day. ThatÂ’s the beauty of this mid-tier performance segment. After looking at their specs, it shouldn't be surprising that the M340i is the quicker of the two here. Its 382 horsepower and 368 pound-feet of torque hit noticeably harder from any speed than AcuraÂ’s 355 horses and 354 pound-feet of torque. The Acura is also carrying an extra 232 pounds of curb weight over the Bimmer, which makes the M340iÂ’s 1-second advantage in the 0-60 mph sprint make perfect sense. For the record, BMW quotes a 4.1-second time, and Acura only offers an approximate time of 5 seconds. Both estimates feel accurate. Beyond sheer acceleration, both engines offer up their own version of tingly feel-goods. BMWÂ’s inline-six is as smooth as ever as it plays its sonorous note all the way to the 7,000 rpm redline. There are few sounds in the automotive universe that surpass the glee we feel when listening to a BMW inline-six at full-chat, and that rule still applies to the M340i.

Acura recalls 7,387 new RLX sedans over suspension bolts

Acura has announced a recall for the 2014 RLX due to improperly tightened rear suspension bolts that could come loose and increase the risk of a crash. The National Highway Traffic Safety Administration has yet to formally issue a recall notice for the RLX, but Acura says that a total of 7,387 RLX sedans are affected, which seems to include markets outside of the US as there have only been 4,456 of the sedans sold through November.
While there isn't an official NHTSA statement, there is one complaint on the government agency's site for a similar incident that caused a driver to almost lose control of the vehicle. Recall notices will be mailed out to customers starting next month, but in the meantime, Acura has issued a press release, which is posted below, and includes contact information that will be useful for affected RLX owners.
