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.

Vert-A-Pac train cars kept your Chevy Vega's price in check

Our apologies to those who've seen this before, but for the rest of the class, how awesome are these pictures of the Vert-A-Pac shipping system General Motors came up with to ship the Chevrolet Vega back in the 1970s? Developed along with Southern Pacific Railroad, GM was able to double the amount of Vega models it could ship by packing them into the unique storage cars vertically.
At the time, rail cars could fit 15 vehicles each, but Chevrolet was able to lower shipping costs by making it possible to ship 30 Vegas per rail car, in turn allowing the price of the Vega to remain as low as possible. Each rail car had 30 doors that would fold down so that a Vega could be strapped on, and then a forklift would come along and lift the door into place. All the cars were positioned nose down, and since they were shipped with all of their required fluids, certain aspects had to be designed specifically for this type of shipping, including an oil baffle in the engine, a special battery and even a repositioned windshield washer reservoir. See for yourself in our image gallery above.

Should Chevrolet continue the SS for another generation?

It is no shocker to say that Chevy kinda messed up with the SS. Now before everyone gets their facts and figures out, lets be real. The SS probably shouldn't have happened in the first place. Chevy hardly promoted the car when it released. It quietly came to our shores (the SS is really a Holden VF Commodore). It was the same with the Pontiac G8 before GM axed the brand. With the G8 however, it got more attention due to the heavy marketing Pontiac did with the car despite the low sales numbers. The SS fills the void of a performance sedan for Chevrolet mainly because there isn't a Impala SS sedan anymore. The SS also shares the same platform with the Chevrolet Caprice PPV, a fleet vehicle only available for your local police station since again the Impala doesn't fill that void any longer. But should the SS continue on in a future life? My answer: No! It was great for Chevy to do this little experiment, and I am sure they learned a lot from releasing the SS and the Caprice as well. But why not take the essence of both of those vehicles and combine them into a new next generation Impala. The Impala SS can return once again in a proper way, and a PPV version of the Impala can go into production. Kinda like what Ford and Dodge did with their performance and police versions of the Taurus and Charger. There really isn't a need to have 2 extra models in the line up when the Impala can fill all 3 voids. With the Holden VF Commodore going out of production in 2017, the Chevrolet SS may not be around much longer. There are rumors that the Commodore will live on in a new global vehicle, so if that is true it could mean the end of the RWD V8 sedans from Australia. But Chevrolet could continue the formula of the SS in the Impala, and it may turn out to be very successful for them. Image Credit: Chevrolet Chevrolet open road
