2013 Mercedes-Benz GLK250 Bluetec gets 33 mpg, priced from $38,950*

It's been more than a year since we first saw the 2013 Mercedes-Benz GLK250 Bluetec unveiled at the 2012 New York Auto Show, but it looks like the compact diesel crossover is finally starting to roll into dealerships. Those wanting to buy a diesel GLK will only have to pony up an extra $1,500 over a base, gas-powered GLK350, as the GLK250's starting price is listed at $38,590 (*not including $905 destination charge).
The turbocharged 2.1-liter four-cylinder diesel produces 200 horsepower and 369 pound-feet of torque, and Mercedes-Benz has also provided some fuel economy numbers for this model, with claimed EPA estimates of 24 miles per gallon city and 33 mpg highway. There is no listing for the GLK250 on the EPA's website yet, but the figures represent significant increase over the GLK350's lackluster 19 mpg city and 25 mpg highway figures, which are for the rear-wheel drive model. The GLK250 comes standard with the 4Matic all-wheel-drive system - a $2,000 option on GLK350 - meaning that if you want an all-wheel-drive version of the 2013 GLK, it's actually cheaper to opt for the diesel model. Head over to the Mercedes-Benz site for the full 2013 GLK-Class configurator.

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.

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.
