2021 BMW M3 and M4 vs all the high-powered sport sedans and coupes

Should you have a found a way to get past that schnoz, you've probably digested some of the basic specs for the all-new 2021 BMW M3 sedan and M4 coupe specs. They're plenty impressive. There's also, basically, two sets of them thanks to the regular and Competition versions that differ in engine output and transmission type.  But how do they compare to other ultra sport sedans and coupes? Well, we were wondering that too, so we fired up the Autoblog Comparison Spreadsheet Generator 5000 (aka me chained to my computer in a dark basement).  Sadly, there are surprisingly few competitors for the 2021 BMW M3. Rival sedans include the Mercedes-AMG C 63 and the Alfa Romeo Giulia Quadrifoglio, along with the Audi RS 5 Sportback sedan/coupe/hatchback thing. There's no more Lexus IS F, the Cadillac CT4 Blackwing has yet to arrive and Jaguar doesn't offer a spicy XE R.  Happily, there are more coupe rivals for the 2021 BMW M4, including the two-door versions of the AMG and Audi as well as the Lexus RC F. I also included the Ford Shelby GT350 and Chevrolet Camaro SS 1LE. On paper, they align incredibly well. On the street and on a track, I can personally attest that these Americans are fully capable of keeping up and/or bettering the fancy-pants luxury brands (and let's not forget there are even more powerful, hardcore versions available). If they don't align in terms of price or prestige, whatever. OK, let's get to the spreadsheet. Let's start with the coupes and note that I didn't bother listing the dimensions for the M4 Competition and C 63 S as they are identical to their "lesser" siblings.  I won't bother burning words explaining what you can see on the chart. Instead, I'll point out a few things that stood out to me. First, BMW M comes awfully close to matching the output of AMG's twin-turbo V8 despite having two fewer cylinders. Similarly, Audi manages to better the 0-60 time of the M4 Competition and tie the C 63 S despite being WAY down on power. It's not like it weighs less. Magic? Second, and speaking of 0-60 times, remember the importance that transmission and drivetrain make with them. It's not just horsepower and torque. An automatic will be quicker and easier to launch than a manual, while all-wheel drive provides more instantaneous and beneficial grip.

Audi R8 V10 Plus vs. Renault Clio Cup racecar will make you go hmmm...

Match up a hot hatch with a supercar of the same vintage, and we'll tell you who will win every time. It's easy, really, as the supercar invariably features a more advanced suspension, stickier tires and most importantly, more power. What if the hot hatch is race prepped, though?
In that particular case, all bets are off. A circuit-tuned suspension, a stripped-down cabin, an ultra-quick sequential transmission and the greatest equalizer of them all, slick tires, are all that's needed to turn the typical hot hatch into a proper dragon slayer.
Perhaps seeking to prove this, Evo has put together an interesting head-to-head between the Audi R8 V10 and a race-prepared Renault Clio Cup. Host Dickie Meaden takes us through each car, highlighting the bits and bobs on both sides which should make this a tight competition. And boy, is this one tight.

Recharge Wrap-up: BMW i3 carshare, Audi e-gas plant

Elix Wireless has announced its E10K Wireless Charging System. The system is designed for harsh conditions, delivers up to 10 kilowatts and features automatic detection and removal of foreign objects. Its low frequency makes it safe to operate near oil and gas, and in other hazardous environments. The system can charge personal vehicles, as well as electric buses, trucks, mining equipment and heavy duty machinery. Elix has "created an entirely new technology that meets customer demand for fast, safe and reliable charging," says, CEO David Smith. The E10K system uses Elix's Magneto-Dynamic Coupling technology, with rotating permanent magnets in the transmitter and receiver. Read more at Green Car Congress, or in the press release from Elix Wireless. FreeWire Technologies and Siemens are working together on a pilot program for the Mobi Charger. The mobile charging station, which uses second-life EV batteries to charge electric vehicles, will be deployed for a trial at LinkedIn's campus in Mountain View, CA. The Mobi is more flexible than stationary chargers in that it brings the charging to the car, regardless of where it is parked, rather than having to park the EV in a specific spot. It can charge up to five cars per day without putting stress on the grid during peak hours. Read more from Siemens. Audi's e-gas plant in Werlte, Germany helps stabilize the power grid. The plant, which produces synthetic methane using CO2, water and electricity, is able to draw six megawatts of power within five minutes, allowing it to become certified in the electricity balancing market. This helps the grid adapt to the larger load fluctuations that go hand-in-hand with generating renewable energy. It also allows the plant to achieve higher operating times and produce more e-gas each year. Read more in the press release from Audi. The BMW i3 is now available through the DriveNow carsharing service in Germany. DriveNow, which is a joint venture between BMW and car rental company Sixt, has put 100 i3s into service in Berlin, Hamburg and Munich. BMW also says that it supports a shift away from private car ownership in order to improve urban living and mobility, and sees electric carsharing as an important part of that. "We are witnessing the changes our customers and society as a whole are making and we are taking them on board," says BMW's Dr. Bernhard Blattel.
