Race recap: 2016 Bahrain Grand Prix was everything good and bad about F1

Nothing was as it seemed heading into Bahrain. We were told team bosses had nixed the qualifying experiment that flunked every test by every measure in Australia, but that didn't happen. The FIA didn't give the teams the option of a wholesale return to the old format, the governing body only held a vote on whether to revert back to the old format in Q3 but stick with elimination gimmicks in Q1 and Q2. McLaren and Red Bull dissented, denying the chance for hybrid rounds. We're surprised none of the smaller teams voted against since elimination qualifying is hardest on them. Given the chance to fix the system again in Bahrain, Formula 1 failed again. The FIA and Bernie Ecclestone don't want to go back to the old system – because the race promoters don't want to go back to the old system – so all we know for sure is that there will be more meetings. We also thought Fernando Alonso would race in Bahrain after being given medical clearance, but a follow-up scan by the FIA showed fractured ribs and a damaged lung, ruling him out. And we thought Ferrari might have the pace to conquer Mercedes-AMG Petronas this year – and they might yet, but not on Saturday. That's why the Bahrain race began with another Mercedes one-two, Lewis Hamilton ahead of Nico Rosberg, Ferrari drivers Sebastian Vettel and Kimi Raikkonen behind. The Australian outback is plagued with rabbits, which must have something to do with how Daniel Ricciardo keeps pulling them out of his helmet; the Aussie got his Red Bull up to a surprising fifth on the grid. Williams drivers Valtteri Bottas in sixth and Felipe Massa in seventh would need to get him out of the way quickly to show what the car can do after an unsatisfying race in Australia. Nico Hulkenberg lined up in eighth for Sahara Force India. As proof the qualifying format failed again with its sophomore attempt, the last five minutes of Q2 were disappointing. Hulkenberg had the track completely to himself for his quali run, the only two cars on track after him were the Williams duo who weren't setting a time, but getting a set of soft tires ready to start the race on. As for Q1, the only reason for on-track action in the last three minutes was because Hamilton flubbed his first timed run. Romain Grosjean continued Haas F1's fruitful start to the season with ninth place, ahead of Max Verstappen in the Toro Rosso closing out the top ten. At the end of a long red light to start the race, Rosberg claimed his right to victory before Turn 1.

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.

Mercedes-Maybach SL 680 Monogram Series gives the rich and famous what they want

TOPANGA, Calif. – Give the people what they want, right? Especially if they're extremely wealthy. And possibly famous.  Apparently, the requests for a convertible Maybach from existing owners and/or celebrities were so frequent and insistent that the uber-luxury offshoot of Mercedes-Benz finally decided to give them just that. The 2025 Mercedes-Maybach SL 680 Monogram Series answers the call. While all other Maybachs are based on a Mercedes-Benz, this is the first Maybach to be based on a car developed by AMG: the current-generation SL 55 and SL 63. This presented a greater challenge to engineers than past efforts. Although a sportier Maybach was intended (as opposed to modern Maybach's first drop-top effort, the Maybach S 650 Cabriolet), the SL 680 is, not surprisingly, seeking a much different dynamic end goal than its AMG-only cousins. According to Maybach product manager Hannes Meyer, the far shorter wheelbase than the Maybach norm was a particular challenge in making sure that its convertible offering maintained "the same ease and nearly floating driving experience" expected of the brand. To that end, the Maybach SL shares the SL 63's air suspension and trick AMG Active Control interconnected hydraulically controlled dampers, but the tuning is changed, especially with the rear air springs as the driver sits closer to those. Meyer says the damper valves in particular have a greater range between sportiness and comfort than the SL 63. The steering system is totally Maybach-specific, including a different ratio and more upright front camber, resulting in what Meyer described as a more stable and less aggressive setup than what you'd find in the SL 63.  Before you start looking for a 6.8-liter engine in the Mercedes arsenal, remember that those numbers don't really mean anything anymore. The Maybach SL 680 has exactly the same 4.0-liter twin-turbo V8 as the SL 63 good for 577 horsepower and 590 pound-feet of torque. The nine-speed AMG transmission is the same in terms of hardware, but it has totally different software. In particular, the 2-3 and 3-4 shifts are most different in order to provide a smoother, more Maybach acceleration experience. The 4Matic+ all-wheel-drive system is also shared, but is programmed to have a more balanced front-to-rear power split than the rear-biased AMG. Finally, the exhaust has been retuned. Meyer said that up to 2,800 rpm, the exhaust isn't quieter than what you'd experience in the AMGs, it just has a different tone.
