From a fast-moving electric car, to a big-spending central banker, this is The Week in Numbers.1.99 seconds is how long Tesla's new model takes to get to 60 miles per hour. Company boss Elon Musk hopes the Model S Plaid will help fend off growing competition from the likes of Porsche and Mercedes, and he says the performance isn't just for bragging rights: "We've got to show that an electric car is the best car. Hands down. You know, so it's got to be clear. It's like, man, this is... Sustainable energy cars can be the fastest cars, can be the safest cars, can be the most kick-ass cars in every way." €80 billion, or about $97 billion, is how much the European Central Bank has been spending every month this quarter to buy debt and pep up the region's economy. At Thursday's bank news conference analysts watched for any sign that the splurge was about to end. But ECB president Christine Lagarde said it was no time to change direction: "As I said, steady hand." 429.9% was the gain for shares in Aethlon Medical on Wednesday. It was that day's darling for meme stock fans on Reddit. Wild gains and losses came for other U.S. shares this week, including Clover Health. The retail investors were once again targeting stocks subject to short selling by big market players. 5% was the annual rate of inflation in the U.S. in May. That means prices are rising at their fastest pace since the summer of 2008. But the monthly rate edged down, lending support to the Federal Reserve's claim that inflation isn't running away. And 27.6% was the record annual jump in UK GDP in April. The number suggests the country's economy - the world's fifth biggest - is recovering, as shops reopen and streets come back to life. But economic output is still lower than it was before the global crisis.
