The Mercedes-AMG SL has gained a new entry-level variant featuring turbocharger technology that, the firm says, is directly derived from Formula 1 . The rear-wheel-drive SL 43 is powered by a 2.0-litre four-cylinder turbocharged petrol engine, producing 375bhp and 354lb ft of torque. The model also benefits from a 12bhp boost from a 48V belt-driven starter-generator. As standard, the SL 43 is equipped with an electric exhaust gas turbocharger, which, Mercedes says, is a world first for a series-production vehicle. The technology, which is the same as that used on Mercedes-AMG F1 cars, adds a 4cm-thick electric motor to the turbocharger shaft. It drives the turbocharger directly, which, Mercedes claims, “significantly improves immediate response from idle speed and across the entire engine speed range.” Mercedes says it provides the SL 43 with a more dynamic driving experience, optimising acceleration and accelerator in...
We already tested the EQS580 , but this is our first go in the 450+. The test results were predictable. Down 187 hp and a driven axle to the EQS580, the 450+ takes 1.7 seconds longer to reach 60 mph. That's quite a disparity, given how the 450+ is nearly 300 pounds lighter, but remember: The less powerful EQS still weighs more than 5,500 pounds. Around town, there is plenty of pep for shoehorning the large EQS into gaps in traffic, but acceleration tapers off noticeably above freeway speeds. As for range, the EPA says a 2022 Mercedes-Benz EQS450+ can do 350 miles on a single full charge (just 10 more than an EQS580). We put more than 200 miles on our test car during a week of parking it outside overnight in cold weather without charging, after starting with an almost-full battery pack (with about 300-some miles of range showing) and never once worried we'd run out of juice. Each night the battery would lose some range (again, we didn't plug it in). At the end of the w...
With the arrival of the new Kia Sportage , it's clear that the comapy execs at the apex of Kia ’s corporate hierarchy apparently don’t like to dwell on the company's heritage, and perhaps that's understandable. Kia's rapid transformation from dumpy, irrelevant duckling to unambiguous class leader (hello Kia EV6 ) borders on the stuff of industrial legend. Conversely, the people now tasked with marketing the company as a high-tech neophyte and legitimate premium-brand challenger feel that the less the public knows about its rustic back catalogue, the better. Sure enough, the original Sportage – built on a Mazda Bongo van platform – is no Benz 540K, but it’s worth looking up simply to appreciate the progress that Kia has made since designer Peter Schreyer arrived from Audi in 2006. The bold new Mk5 Sportage, built on a proprietary platform honed for European roads, won’t be to all aesthetic tastes, but it possesse...
