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.

German police Corvette promotes safe aftermarket tuning

The German organization Tune It! Safe! promotes safe, legal vehicle tuning in the country, and it probably doesn't have to worry about anyone breaking the law when this Polizei-themed Chevrolet Corvette is on the scene. The Vette is on display at the Essen Motor Show and is the group's latest police-wrapped tuner car, following models like the Brabus Rocket, Mercedes-Benz CLS, and AC Schnitzer-tuned BMW 123d in years past. Tikt Performance did the tuning this time, and the German company added a full carbon-fiber body kit for the Vette, including a front lip, side sills, rear spoiler, and relatively understated wheel flares. It also installed forged wheels that measure 19-inches in front and 20-inches in back and wrapped them with Hankook Ventus S1 Evo tires. To really let the coupe look the part of a proper Polizei car, the tuners included police lights from Hella and the appropriate blue-and-white wrap. Tikt left the 6.2-liter V8 alone to produce 460 horsepower and 465 pound-feet, and the power routes through a seven-speed manual. Even with the stock performance, this police-themed 'Vette would still look fantastic blasting down the Autobahn with the lights flashing. World premiere at the Essen Motor Show: initiative for safe tuning starts the new campaign year with TIKT Performance Corvette A powerful look for a powerful campaign: TUNE IT! SAFE! presents innovative design and maximum precision Innovative design, maximum precision and unique performance – with an enhanced Corvette, TUNE IT! SAFE! shows that attractive, creative tuning in no way has to conflict with legal requirements. In the new campaign year, the seventh generation of a sports car icon stands as a symbol and shining example of safe automobile tuning and 100 per cent driving fun. The campaign car of the initiative for safe tuning, sponsored by the Federal Ministry of Transport, the Association of Automobile Tuners (VDAT) as well as numerous other organisations and institutions, sees its premiere at the Essen Motor Show (Hall 10, Stand F104). TUNE IT! SAFE! also continues its partnership with premium tyre manufacturer Hankook. Tuning specialist TIKT Performance based in Upper Bavaria is responsible for the innovative conversion of the new TUNE IT! SAFE! police car.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.
