Britain orders 10,000 ventilators from F1/McLaren/Mercedes/Ford/Rolls-Royce/Airbus

Paramedics and ambulance personnel get instructions from a command unit outside London's ExCel Centre arena, which is being turned into a 4,000 bed temporary hospital called NHS Nightingale to deal with coronavirus patients. The hospital is due to open Monday, March 30. / AP     LONDON — Britain has ordered 10,000 ventilators from a consortium of leading aerospace, engineering and Formula One racing companies which will start production this week in response to an urgent government call for industry to help save lives. The 27-strong team, including Airbus, BAE Systems, Ford and Rolls-Royce, have joined forces to ramp up production of a ventilator made by Smiths Group, which supports those with complications from COVID-19. The consortium, which also includes seven Formula One teams including McLaren and Mercedes, home to World Champion Lewis Hamilton, said they had pulled staff off existing projects to meet the national need. Some 1,228 people have died from coronavirus in the United Kingdom and a senior health official said on Saturday the country would be doing well if it manages to keep the death toll below 20,000. "This consortium brings together some of the most innovative companies in the world," Dick Elsy, the head of the consortium, said in a statement. "I am confident this consortium has the skills and tools to make a difference and save lives." The United Kingdom, which initially only had 5,000 ventilators available in its National Health Service, has been trying to secure additional supplies after realising it needed 30,000 to cope with the peak of the outbreak. Prime Minister Boris Johnson, who is now in isolation in Downing Street after testing positive for coronavirus, made an emergency appeal earlier this month for manufacturers to retool their production lines and start making specialist health equipment including ventilators. Britain now has about 8,000 ventilators, with another 8,000 on order from international manufacturers that are due in coming weeks. Last week it placed an order for a newly-designed model from the vacuum cleaner company Dyson that will need to be approved by the health regulator. Mercedes part of a separate effort, too Separately on Monday a second consortium including Mercedes Formula One and other F1 teams said it had developed in less than a week a new version of a breathing aid that can help coronavirus patients.

2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
