F1 cancels season-opening Australian Grand Prix over coronavirus

Workers pack up in pit lane after the cancellation of the Australian Formula One Grand Prix in Melbourne, Friday. / AP   MELBOURNE, Australia — As thousands of fans queued to get into the Australian Grand Prix, seemingly unperturbed by the coronavirus pandemic, the Formula One teams and drivers were packing up to leave. The rapid spread of the virus left organizers with little choice Friday but to cancel the season-opening race, particularly after McLaren withdrew because a team member tested positive for the COVID-19 illness and following heavy criticism from six-time world champion Lewis Hamilton. The two practice sessions that usually showcase what the teams have been improving in the off-season were less than two hours from starting when the decision was publicly announced. Principals of nine F1 teams and organizers met overnight and “concluded with a majority view of the teams that the race should not go ahead," a joint statement by FIA, motorsport's governing body, local organizers and F1 said. “It's been a very fluid situation," F1 chairman Chase Carey said. “We're all disappointed not to have it, but I think we've made the decision we had to make." “It's not like it came out of the blue," Carey told a news conference beside the F1 paddock that ended in light rain. “A week ago, when teams started traveling here, we felt it was the right decision (to stage the race). Clearly the situation changed in the interim." Practice, qualifying and Sunday's race were all scrapped, casting doubt over the Bahrain Grand Prix which is scheduled to be held next week and the Vietnamese GP, scheduled for April 5. Authorities in Bahrain have already said no fans will be allowed into the circuit. Carey said a decision on whether or not to go ahead with the the race would be made in coming days. The Chinese GP has already been postponed from April. Hamilton used the first official news conference with F1 drivers in Melbourne to say he was shocked that organizers planned to proceed with the Australian Grand Prix, which regularly attracts more than 300,000 people over four days. McLaren's decision to withdraw was ultimately the catalyst for the cancellation. That person and 14 other McLaren team members have been placed in quarantine in a Melbourne hotel for 14 days. Hamilton's Mercedes-AMG Petronas team said it sent a letter to the FIA and F1 requesting the cancellation and had commenced preparations to leave before the decision was publicly announced.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

Mercedes G 500 4x4 is mighty mean and bright lime green

The Mercedes-Benz G500 4x42, finally ready to meet the crowds at the Geneva Motor Show, might just be the best factory-prepped expedition off-roader on the market, should Mercedes choose to build it. The short story is that some well-heeled admirers of the G63 AMG 6x6 said, "It's nice, but can you take it down a notch?" And by "notch" they meant "an axle." So the G500 4x42 gets just two portal axles instead of three, and a slew of other features. The 4x4 squared offers up a standard G-wagen body, but instead of the 5.5-liter twin-turbo V8 from the G63, there's a new 4.0-liter twin-turbo V8 with 422 horsepower and 450 pound-feet of torque. Compared to the standard G500, the track is 11.8 inches wider, the street-cred rims being 22-inchers on 325/55 R-series tires. When it's time to get dirty, they can be swapped for an optional set of 18-inch wheels with 37-inch beadlock tires. With that setup and the same wheelbase as the G500 LWB, ground clearance and fording depth are more than doubled to 17.7 inches and 39 inches respectively, the angle of approach goes from 36 degrees to 52 degrees and the angle of departure leaps from 27 degrees to 54 degrees. Breakover angle is bumped from 21 degrees to 47 degrees, a two-piece stainless steel undertray protecting the sensitive bits when you push it. The only parts that get a raised eyebrow are the carbon fiber wheel arches and bumpers, which might behave badly when they meet an immovable granite object. To escape the sensation of driving the Taj Mahal in urban environments, there's a twin spring-and-damper setup at each wheel. One of the spring-damper combos is electronically controlled and adjustable, and when called into action via the Comfort or Sport mode, takes control of wheel action; even when passive, it will kick in to automatically to stiffen the body if it detects evasive maneuvers. On top of all that, to remind you that you're in a Mercedes the interior is fitted out with Designo leather trim and diamond-quilted microfiber. Mercedes is going to gauge its Geneva reception before deciding to build it, a hurdle we're sure will be overcome. Car and Driver drove it and verified it's the real deal, with pricing - if it's built - speculated to land between the G63 AMG and G65 AMG. The press release below has all the details.
