Mercedes-Benz cut fleetwide emissions by 4.3 percent last year

Mercedes-Benz says it reduced its fleetwide vehicle emissions by 4.3 percent last year. Of course, the German automaker has another 29 percent to go to meet the European Commission's 2020 mandate. But who's counting? Mercedes' luxury and sports car bent has made it a relative laggard when it comes to increasing fleetwide fuel-efficiency, but the company did reduce emissions from 140 grams of CO2 per kilometer to 134 last year. The company's fleetwide fuel efficiency (calculated using the lenient European standard) was 5.4 liters per 100 kilometers, which equals about 44 miles per gallon and represents a 25-percent jump since 2007. Benz has come a long way from its gas-swilling V8 tanks of the 1970s. In fact, the company said its top performer, in the fuel-efficiency sense, was the diesel-powered B180 CDI BlueEfficiency Edition, which consumes 3.8 liters per 100 kilometers. That equals about 62 mpg (again, on the lenient scale). The company got some additional good press by revealing that Winfried Kretschmann, Minister-President of the German State of Baden-Wurttemberg, drives a Mercedes-Benz S300 BlueTEC Hybrid. Not exactly a Nissan Leaf, mind you, but it's a start, as is the company's efforts to bring its fleetwide emissions ever closer to the 95g CO2/km level that the EC is mandating by 2020. Take a look at Mercedes-Benz's press release below. Minister-President of the German State of Baden-Wurttemberg, Winfried Kretschmann (left), with Prof. Dr. Thomas Weber (right) and a Mercedes-Benz S-Class S 300 BlueTEC HYBRID Fleet fuel consumption for Mercedes-Benz Cars falls to 134 g CO2/km: Top efficiency figures in all vehicle classes Stuttgart, Apr 08, 2014 Benefit for the environment and customers: In almost all vehicle classes, Mercedes-Benz offers the most efficient vehicle in the competitive lineup. Moreover, in 2013 the company was able to reduce the fuel consumption and CO2 emissions[1] of the Mercedes-Benz Cars EU new vehicle fleet by a further six grams, to 134 g CO2/km. This means that in 2013, the average fleet consumption was 5.4 litres/100 km – a reduction by 24.7 percent since 2007. At present the company offers more than 50 models emitting less than 120 g CO2/km and 71 models emitting less than 130 g CO2/km. Customers can find vehicles in the Mercedes-Benz model range that consume considerably less fuel than competing models. "With our model initiative we want to be the leading premium manufacturer by 2020 again, says Prof.

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

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.
