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 Volt sales drop in June, Nissan Leaf inches upwards

Different month, same story. That's the gist of the monthly US sales numbers from the Chevy Volt and the Nissan Leaf. These were the first two mass-market plug-in vehicles to go on sale in the US and we've been comparing their sales numbers for what seems like ages now. So far, the 2014 tale of the tape shows the all-electric once again trumping the plug-in hybrid. The last time the Volt outsold the Leaf was in October 2013. Chevrolet sold 1,777 Volts in June. That was good enough to be the Volt's best sales month of the year, but it's down 34 percent from the 2,698 units sold in June 2013. In fact, it's on par with the 1,760 Volts sold in June 2012. Given the steady sales, General Motors might need to push up the release of the next-gen Volt to gin up excitement, especially if it also offers some of the things that current Volt drivers say they want improved: more range, a lower price and a fifth seat. GM also said it sold 85 Spark EVs in June, an increase of 215 percent over June 2013 Nissan sold 2,347 Leafs last month. The good news continues for Nissan, which says it sold 2,347 Leafs last month. That's an increase of 5.5 percent over 2013 numbers and makes 2014 the best June ever for Leaf sales. Let's credit Texas. Toby Perry, Nissan's director of EV sales and marketing, said in a statement that, "Since the Texas state incentive went into effect in May, we've seen a big jump in Leaf sales in the Austin, Dallas and Houston markets. Our dealers are telling us that they saw more traffic in their stores, and they had their best Leaf sales performance in the last weekend in June." Even with that increase, Atlanta remains the top Leaf market. Nissan has sold 12,736 Leafs in the US so far this year; Chevy 8,615 Volts. Our detailed monthly sales write-up of green cars in the US, including plug-in vehicles, hybrids and diesel cars, is coming soon. For now, we invite you to discuss these numbers in the Comments.

Camaro spy shots show subtly different grille, front fascia

It looks like there some changes in store for the Chevrolet Camaro - the only thing is that we just don't know what Chevy has up its sleeve. Looking at these spy shots, we'd initially be inclined to think that there is just a minor facelift or a new special edition, but upon closer inspection, there are a few oddities about this car that definitely have us intrigued.
The most obvious difference on this prototype is the slightly restyled front fascia with a smaller lower air inlet and the two-bar grille. Then we get to some of the car's mysterious details. For starters, this fascia has the SS vent above the grille, but it looks to be blocked off. Granted this could just be a one-off piece used for testing. What really piqued our interest was at the rear of the car where it has quad exhaust outlets that are used on the ZL1. Could this be the LS7-powered Camaro that we reported on back in December?
At this point, your guess is as good as ours as to what we're looking at here, so let us know in the comments what you think this could be.
