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.

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.

Automakers suspend some business in Russia following invasion

(Getty Images)   Global auto and truck makers, including Sweden's Volvo Cars and Germany's Daimler Truck, on Monday suspended some business in Russia following that country's invasion of Ukraine. Russian forces invaded Ukraine last week, marking the biggest attack by one state against another in Europe since World War II. Many firms have idled operations in Russia following Western sanctions against Russia. Energy giant BP Plc, Russia's biggest foreign investor, abruptly announced over the weekend it was abandoning its 20% stake in state-controlled Rosneft at a cost of up to $25 billion. On Monday, Swedish automaker Volvo Cars said it would suspend car shipments to the Russian market until further notice, becoming the first international automaker to do so as sanctions over the invasion continue to bite. In a statement, the company said it had made the decision because of "potential risks associated with trading material with Russia, including the sanctions imposed by the EU and US." "Volvo Cars will not deliver any cars to the Russian market until further notice," it said. A Volvo spokesman said the carmaker exports vehicles to Russia from plants in Sweden, China and the United States. This came as Russia warned Sweden and Finland not to join NATO or risk facing “serious military-political consequences." Volvo sold around 9,000 cars in Russia in 2021, based on industry data. Earlier on Monday, RIA news agency reported Volkswagen had temporarily suspended deliveries of cars already in Russia to local dealerships, citing a company statement. VW had no immediate comment when contacted by Reuters. VW previously said it would halt production for a few days this week at two German factories after a delay in getting parts made in Ukraine. Daimler Truck said on Monday it would freeze its business activities in Russia with immediate effect, including its cooperation with Russian truck maker Kamaz. Mercedes-Benz Group is also looking into legal options to divest its 15% stake in Kamaz as quickly as possible, the Handelsblatt newspaper reported. A Mercedes spokesperson told Reuters business activities would have to be re-evaluated in light of the current events. Mercedes-Benz Group, formerly Daimler AG, was the parent company of Daimler Truck before the truck maker was spun off.
