Mercedes A-Class refresh includes crown-stealing 381-hp A45 AMG

We're sure the 362-horsepower Audi RS3 Sportback enjoyed its brief reign at the top of the hot-hatch horsepower charts. But now, Mercedes-Benz updated the A-Class so that it reclaims the throne, castle, and jewels: the Mercedes-AMG A45 4Matic comes with 381 hp from its turbocharged 2.0-liter four-cylinder, a significant bump of 36 hp, and 350 pound-feet of torque, an increase of 18 lb-ft. The seven-speed dual-clutch gearbox gets shorter ratios from third to seventh gears, so its 0-62 mile-per-hour time has dropped from 4.6 seconds to 4.2 seconds. The A45 gets a Dynamic Select system – driving modes controlled by a rotary knob – that comes standard with four modes: Comfort, Sport, Sport +, and Individual. Opt for the AMG Dynamic Plus package and you get a mechanical locking differential on the front axle, the two-stage AMG Ride Control sport suspension with adaptive damping, and a Race mode. Outside, additional aero aids are applied to the nipped-and-tucked bodywork changes made to the entire A-Class range. The spoiler lip under the new front bumper, rear roof spoiler, and rear diffuser, create more downforce than before. Inside, the new flat-bottomed steering wheel is joined by sport seats that allow bolster depth adjustment. And for all those upgrades, fuel economy has stayed the same at 6.9 liters per 100 kilometers on the European cycle. Even away from that tectonic shift, Mercedes made plenty of changes to the A-Class landscape. The new front bumper is said to be "more arrow-shaped," in homage to the the Concept A-Class from 2011, that stretches its look horizontally. LED headlights, standard on the A45, are optional here, and are paired with interior ambiance lighting. In back we get new taillights and some angular exhaust finishers laid into a diffuser-like insert, an alteration we're seeing across the entire Mercedes line-up. Inside, you'll find a redesigned instrument cluster with new graphics, higher-quality finishes on the switchgear, seats with adjustable bolster length, and new color options. Four driving modes are incorporated into the Dynamic Select system: Comfort, Sport, Eco, and Individual. The Eco mode has been tweaked to return even more fuel savings. This Mercedes is also the first to incorporate Apple CarPlay and MirrorLink for the non-iOs smartphoners.

E.U. executive conditionally approves Daimler, BMW car-sharing deal

BRUSSELS — The European Union's competition authority said on Wednesday it had approved the plan of German luxury carmakers Daimler and BMW to combine their car-sharing businesses, subject to conditions. Under the deal, which includes car-sharing units Car2Go and DriveNow as well as ride-hailing, parking and charging services, Daimler and BMW will each hold 50 percent stakes in a joint venture. They have offered concessions to address E.U. antitrust concerns over the deal they hope would let them better compete with U.S. rival Uber and China's Didi Chuxing. The European Commission has found the deal would raise competition concerns for free-floating car sharing services in Berlin, Cologne, Duesseldorf, Hamburg, Munich and Vienna. It said Daimler and BMW agreed to a remedy package in the six cities. "The commitments thus fully address the Commission's concerns as they will reduce the barriers to entry for competing free-floating car sharing providers," the Commission said in a statement. "Therefore the Commission concluded that the proposed transaction, as modified by the commitments, would no longer raise competition concerns. The Commission's decision is conditional upon full compliance with the commitments." Reporting by Gabriela Baczynska and Philip Blenkinsop. Related Video:

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.
