Fastest cars in the world by top speed, 0-60 and quarter mile

A claim for the title of “Fastest Car in the World” might seem easy to settle. ItÂ’s actually anything but: Are we talking production cars, race cars or customized monsters? And what does “fastest” even mean? For years, car publications have tended to define “fastest” in terms of an unbeatable top speed. ThatÂ’s distinct from the “quickest” car in a Usain Bolt-style dash from the starting blocks, as with the familiar 0-60 mph metric. Professionals often focus on track lap times or elapsed time-to-distance, as with a drag racer thatÂ’s first to trip the beam of light at the end of a quarter-mile; or the 1,000-foot trip of nitromethane-powered NHRA Top Fuel and Funny Car dragsters. Something tells us, however, that you're not seeking out an answer of "Brittany Force rewriting the NHRA record books with a 3.659-second pass at a boggling 338.17 mph." For most barroom speed arguments, the focus is firmly on cars you can buy in showrooms, even if many are beyond the financial means of all but the wealthiest buyers and collectors. Here are some of the enduring sources of speed claims, counter-claims, tall tales and taunting dismissals that are the lifeblood of car enthusiasts – now with EVs adding an unexpected twist to these passionate pursuits.   Fastest from the blocks: 0-60 mph Thirty years ago, any car that could clock 60 mph in five seconds or less was considered extremely quick. Today, high-performance, gasoline-powered sedans and SUVs are routinely breaking below 4 seconds. As of today, the 2023 Dodge Challenger SRT Demon 170 crushes all with a 0-60 mph time of just 1.66 seconds. That's simply absurd, but keep in mind the Demon was engineered with the single-minded purpose of going fast in a straight line. It's also important to realize that direct comparisons are difficult, because not all of these times were accomplished with similar conditions (prepped surfaces, adjustments for elevation and so on). The moral here is to take these times with a tiny grain of salt. After the Dodge, the Rimac Nevera comes in with an officially recorded 0-60 mph time of just 1.74 seconds. EVs crowd the quickest list, with the Pininfarina Battista coming in a few hundredths slower (1.79 seconds) than the Nevera and the Lucid Air sapphire (1.89 seconds) right after that. Eventually, you arrive to the Tesla Model S Plaid, which has a claimed 1.99-second 0-60 mph time, though instrumented testing by Car and Driver shows it accomplishes the deed in 2.1 seconds.

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.
