Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.

Daimler eMERGE2 test proves ignorance breeds dislike of EVs

Out with the old EVs, in with the new. Daimler announced today that it has finished up the eMERGE electric vehicle project that used Smart Fortwo Electric Drive cars and will now start up eMERGE2, which will use Mercedes-Benz B-Class Electric Drive and PHEV vehicles. As before, the tests will take place in Germany. The first, just-finished eMERGE program ran from May 2013 to June 2015 and put over a million kilometers (621,000 miles) onto 146 Smart Fortwo EDs. Daimler said that over the two years, the vehicle with the most efficient annual energy consumption used just 10.4 kWh for all of its 100 kilometers. The best full-charge range over the year was 161 kilometers (100 miles). Perhaps most interesting, though, was one of the projects findings: "the less an interviewee knew about electric mobility, the more negative their opinion" about the technology. In other words, here's some more proof that getting "butts in seats," as it were, is one reasonable way to promote electric driving. eMERGE: key contribution to developing the mobility of the future Stuttgart/Berlin, Jul 30, 2015 Broad-based real-world trial of eMERGE project completed Especially for daily distances of 50 km or over the E-car is financially attractive eMERGE2 fleet project now launching with 200 Mercedes-Benz B-Class Electric Drive and plug-in hybrid models Stuttgart/Berlin – After more than one million kilometres in two years – from May 2013 to June 2015 – the real-world trial of electric cars known as eMERGE has been completed. Those taking part in the project were private and business customers with 146 smart fortwo electric drive cars from Berlin, Potsdam and North Rhine-Westphalia. Some of them set records: the lowest average energy consumption over one year was 10.4 kWh/100 km, while the longest range was 161 kilometres. The smart fortwo electric drive is certified with a consumption of 16.3 kWh/100 km and a range of 145 kilometres. The broad-based field trial within the framework of the eMERGE project has not only provided information on user behaviour and e-car technology; it also studied intelligent charging systems for improving the utilisation of the power supply as well as various pricing systems with regard to customer acceptance. Based on transport models, the project partners examined the need for a publicly available charging infrastructure. Within the project Daimler was responsible for collecting the driving and charging data required for evaluation of the field trial.

2019 Mercedes-Benz G-Class vs big luxury off-roaders: How they compare on paper

During our first drive of the 2019 Mercedes-Benz G-Class, the all-new SUV's product manager was asked to identify competitors that might have been benchmarked in its development. The look on his face was about the same as if someone had asked him to recite King Lear in Klingon. As far as Andreas Hoeppel was concerned, the G 550 and AMG G 63 doesn't actually have a rival, or at least something the engineers and designers thought to compare it against. The G-Class is a G-Class, who cares what the other guys are doing? Well, in case you care, we figured we'd plug the new G-Class' specs into the old Autoblog Comparo Generator 3000 (TM) to see how the G 550 and AMG G 63 compare to the Range Rover and its mightiest SVAutobiography Dynamic model, plus the Lexus LX 570 and Bentley Bentayga V8. Frankly, Heir Hoeppel was onto something as each of these is wildly different. But, they do share some common elements: giant size and weight, ultra-lux interiors, and far more off-roading capability than other luxury SUVs offer and any of its owners are likely to ever utilize. Sad. So enjoy this trip down specification lane, and if you're still left hungry, you can always check out our Range Rover comparison or create your very own comparo. Off-Road Clearances and Capability All the fancy off-roading software and special cameras in the world won't do you a lick of good if your SUV is too close to the ground or has low-hanging body work that'll get easily ripped off. As such, check out each of these uber-SUV's ground clearance, approach and departure angles, and wading/fording depths. In this case, the Range Rover has an advantage due to its air suspension that can raise itself into an Off-Roading height that's a whopping 2 inches higher than the new G-Wagen. Sadly for itself, Lexus only provides figures for its air suspension when in normal height. It could match or surpass the Range Rover for all we know (but doubt it). As Land Rover does provide figures for the Range Rover's approach and departure angles in normal and Off-Road height, you can get an idea of just how much clearance the new G-Wagen has without any fancy (and expensive to fix) raising and lowering air suspension hardware. In fact, its departure angle is better than even the Range Rover's Off-Road height. Bentley doesn't provide any such information despite touting the Bentayga's surprising off-roading talents.
