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.

Since 2010, Chevy Volt has outsold Nissan Leaf by just two units

The first two plug-in vehicles from major automakers in the US were the Chevy Volt and the Nissan Leaf. Ever since they went on sale to much fanfare in late 2010, we've been tracking the monthly sales with great interest (and, of course, other green vehicle sales as well). After a big initial lead by the Volt – the Volt outsold the Leaf 23,461 to 9,819 in 2012 – the Leaf has been chugging along and outsold the Volt every month since November 2013. We knew that the cumulative totals would soon tip in favor of the Leaf, but for at least one more month, the Volt is going to be able to say its the most popular plug-in vehicle in the US. Overall, for all officially reported sales of the Leaf and the Volt, things are almost exactly tied. Since the vehicles went on sale in the end of 2010 until the end of February 2015, the Volt has sold 74,592 units and the Leaf has sold ... drumroll please ... 74,590 units. For February, Leaf sales totaled 1,198 units, a 17-percent drop from the 1,425 Leafs sold last February. Brendan Jones, Nissan's director of Electric Vehicle Sales and Infrastructure, said in a statement that, "Tough winter weather in several key markets held EV sales back in February. As we head into spring, we look forward to seeing more dealership traffic so shoppers can experience firsthand the benefits of the all-electric Nissan Leaf." Of course, it was cold in the US last February, too, but we're sure that the nasty weather did indeed play a role last month. Things were even worse for the Chevy Volt, which dropped to just 693 copies sold, down 47 percent from the 1,210 sold last year. That's just barely enough for Chevy to keep talking about its plug-in sales leadership, but we expect the message to change once the March numbers come out next month. Related Video:

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
