2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

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.

2016 Italian Grand Prix race recap

The Italian Grand Prix at Monza is called the Temple of Power. Furthermore, the winning driver in Italy started on pole in 13 of the last 16 years, and only one driver in that time has won the Italian GP from behind the front row of the grid: Rubens Barrichello in 2002 and 2009. By this point in the current Formula 1 season (era?) we know what it means when a track emphasizes both power and pole position: Mercedes-AMG Petronas. The Silver Arrows locked out the front row with Lewis Hamilton on pole. A poor start prevented the Briton from capitalizing on the advantage, so teammate Nico Rosberg and four other drivers swept by him before the end of the second turn. Mercedes would later say a clutch issue caused Hamilton's botched start, but that didn't help the man who'd just fallen to sixth place. Rosberg got about two laps of television coverage on his way to an unbothered victory ahead of Hamilton. Ferrari made Hamilton's second-place finish easier by sticking to a two-stop strategy; both Mercedes drivers pitted once. We aren't sure why Ferrari didn't at least attempt a one-stopper once Sebastian Vettel and Kimi Raikkonen had been gifted second and third on track. A pit stop took about 23 seconds from entry to exit and Vettel finished third, six seconds behind Hamilton. Raikkonen finished fourth, another seven seconds behind Vettel. Perhaps the Scuderia's tire usage wouldn't allow longer stints, but we'll never know. Daniel Ricciardo wielded his Red Bull like a scalpel to make an impeccable pass on Valtteri Bottas in the Williams and take fifth place. Ricciardo, trailing another Italian province behind, somehow closed the gap on Bottas in just the braking zone of Turn 1, pulling alongside near the apex without locking a wheel on entry nor running wide on exit. Bottas claimed sixth ahead of Red Bull's Max Verstappen, Sergio Perez in the Force India, Felipe Massa in the second Williams, and Nico Hulkenberg in the second Force India sealing the top ten. Monza did spring a few on-track surprises. Esteban Gutierrez drove Haas F1 into Q3 for the first time this season, the Mexican setting the sixth-best time in Q2. Manor Racing planned for Monza all season, Pascal Wehrlein repaying the effort by qualifying 13th. Fernando Alonso pitted his McLaren on Lap 50 of the 53-lap race for a set of super soft Pirellis, then set the fastest lap. It's Honda's first fastest lap since 1992. The biggest moments happened off the track.
