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.

Chevy reveals new IndyCar aero package

The IndyCar Series is not one that demands its participating teams and automakers to design their own chassis as they do in Formula One, but for this season, the organizers have opened it up to allow for custom aero packages. What you're looking at here is the new look of the chassis to be fielded by teams running under Chevy power. Based on the Dallara DW12 chassis – introduced three years ago and named after the late Dan Wheldon – Chevy's new package is designed for road courses and short ovals, with the speedway configuration to be revealed later. The kit features new wings front and rear and more sculpted side pods. It's also got new wedges at the back to envelop the otherwise open wheels that are a hallmark of Indy racing, a more streamlined engine cover and bigger rear bumper pods. The new package will debut at the Grand Prix of St. Petersburg that will kick off this year's championship in Florida on March 29, followed by the road-course grands prix in Louisiana, Long Beach, Alabama and Indianapolis before the new package needs to be ready for the Indy 500 late in May. Half of the teams on the starting grid this season will be running under Chevy power and are expected to use this new aero kit, with the remaining Honda teams slated to run a different package of their own. Chevrolet Debuts All-New 2015 IndyCar Aero Package Chevy-developed bodywork delivers improved aerodynamics 2015-02-17 INDIANAPOLIS – Chevrolet-powered racecars in the 2015 Verizon IndyCar Series will feature Chevrolet-developed aero packages. Chevrolet introduced the road course/short oval body design today at the Indianapolis Motor Speedway. It is distinguished from the previous racecar with new front wing elements, sculpted side pods and a new rear wing. A speedway configuration for the aero kit, designed for high-speed ovals, will be introduced ahead of its competitive debut at Indianapolis in May. "This is an important milestone in Chevrolet's involvement in IndyCar racing," said Jim Campbell, General Motors U.S. vice president of Performance Vehicles and Motorsports. "We focused on developing an aerodynamic package that delivers an balanced combination of downforce and drag, along with integrated engine performance. It's a total performance package." The new Chevy road course aero configuration delivers greater aerodynamic performance than the previous design.

2016 Chevrolet Camaro: Everything we know so far [UPDATE]

UPDATE: We fully expect the floodgates to open as facts and photos leak throughout the day. Watch this space for more information as it breaks, including these leaked photos, and some new powertrain speculation. Chevrolet has made a grand production of teasing the all-new, sixth-generation Camaro. That slow trickle will become a deluge this weekend, when the 2016 model hits the stage on Detroit's Belle Isle as part of an all-day Camaro-palooza. Considering you're likely to hear plenty about the next-gen muscle car in the next couple days, we figured now is the perfect time to sort out all the facts and rumors we've heard about the next-generation coupe that's coming this weekend. Here's everything we know about Camaro Six. What Will It Look Like? Arguably the easiest Camaro question to answer after all the teasers and spy shots, General Motors' design team favored evolving the current car's retro design language while retaining the same basic shape. The long hood will carry on, joined by an even shorter, wing-topped rear deck, giving the 2016 an almost fastback-like look. The greenhouse is still slim, but lateral visibility may improve slightly owing to the larger quarter windows. We can only hope. The rear end looks to have been rounded, while Chevy's own teaser shows off larger, more prominent taillight housings than the simple rectangular lights on today's car. Expect quad-tipped exhausts to be offered on at least one version of the Camaro. Judging by the single teaser of the car's profile, the rear haunches will be larger and more chiseled. The muscular aluminum hood and its accompanying power bulge are more heavily styled than on today's car, although it looks largely similar in terms of size. It sits atop an even slimmer upper grille that's barely big enough for Chevy's Bowtie logo, with most of the visual mass moving to the gaping lower grille. One of the more tantalizing rumors surrounding the new Camaro focuses on its roof. As evidenced in a rather bizarre round of spy photos, it almost looks like Chevy is considering a removable panel, a la Corvette Stingray. T-tops are also a distinct (and more probable, we hope) possibility. The new shape will result in a more aerodynamic car, and Chevy claims the 2016 Camaro spent 350 hours in the wind tunnel. Overall lift has apparently been cut by 30 percent, thanks partially to a new, smooth underbody panel. Chevrolet has been far less forthcoming with information on the new Camaro's cabin.
