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.

1972 Dodge Challenger on an M1009 CUCV military frame is YES

The subject of this post is cause for celebration, not reason to ask "But why?" We don't know why this random Craigslist seller chose to marry the body of a 1972 Dodge Challenger with the frame and axles from a 1987 Chevrolet M1009 military vehicle. We're here to appreciate it, thanks to The Drive, and maybe spend some time after dinner considering whether to buy it. Now that we're on the same page, an owner in Tucson wants to rid his garage — or his Bullet Farm — of what appears to be an exceptionally well built conversion. Starting from the bottom, the M1009 CUCV, for Commercial Utility Cargo Vehicle or "Cuckvee," emerged from a program turning K5 Blazers into supply rigs that were meant to support hardcore hardware like the AM General Humvee. The M1009 got GM's 6.2-liter Detroit Diesel V8, a TH400 transmission, an NP-208 chain-driven transfer case, a 10-bolt rear axle and 3.08 gears. Produced from 1983 to 1987, they returned "less than desirable" results in the field and the military unloaded them. Not much of that remains for this build. The diesel got dropped, replaced by a 5.7-liter GM gasser with a four-barrel carb and long-tube headers, shifting though a 4L80E automatic transmission attached to a U.S. Shift Quick 1 transmission controller in the cabin. The seller doesn't mention output, but if it's a more recent Chevy 350 then it'll certainly provide a healthy bump over the maximum 160 horsepower from the diesel, especially running through a custom Flowmaster dual exhaust. An NP-205 two-speed transfer case switches between 2H, 4L, and 4H. The Dana 44 front and Dana 60 rear axles feature lockers and 3.52 gearing in back. Skyjacker Black Max provides the suspension to keep the 37-inch BFG KM2 on the pavement or the dirt. About 11,000 miles ago the owner rebuilt and upgraded the drivetrain, installing new accessories like a high-rise intake, four-core radiator, new alternator and Holley fuel pump. Losing the K5 body for an E-body Challenger cap means losing M1009 features like the rifle rack and gas can mounts. But you gain style, something real hard to find on a vehicle stout enough to back you up when you tell the crew, "I've been to hell and I'm going back." As part of that rebuild a few miles back, the minimalist interior got all new panels, dash and custom gauges, headliner, seats, and a Sony audio system with Alpine amps, a sub, and Kenwood speakers.

Callaway, Lingenfelter boost Corvette Z06 way beyond 700 hp

With 650 horsepower and just as much torque on tap, few would accuse the latest Corvette Z06 of being down on power. But for those who'll always demand more, two leading Corvette tuners have just announced new tuning packages for the Z06 to boost Chevy's flagship well beyond 700 horsepower. The more powerful of the two comes from Callaway Cars, which has added a larger supercharger, a triple-action intercooler, and more to increase output to a massive 757 horsepower and 777 pound-feet of torque. The result, according to Callaway, is a 0-60 time quoted at 2.8 seconds and a quarter-mile run in 10.5. The package also includes a reshaped hood, all manner of trim upgrades, and a three-year warranty, and will set you back nearly $17k on top of the cost of donor vehicle that currently lists for $79,000. In what could only come second relative to Callaway's kit, Lingenfelter Performance Engineering has also released a Stage 1 package for the Z06. The kit includes a new dry sump damper, upgraded supercharger pulley and drive belt, and more – all of which Lingenfelter says will boost the Vette's output up to 720 hp and 730 lb-ft. Revised performance figures weren't released, but despite the 37-horse, 47 lb-ft deficit, we doubt it'd trail Callaway's by much. But both would likely leave the stock Z06 in their dust, and you can read more about them in the press releases below.

Equipped with Callaway's GenThree Supercharger, the Corvette Z06 now produces 757 bhp @ 6,200 rpm and 777 lb-ft @ 4,500 rpm (SAE). A launch to 60 mph is now achieved in 2.8 seconds, and a quarter-mile in 10.5 seconds at 131 mph. Why Go Big, When You Can Go Bigger? - Size Matters. To reach that power (which is up from 650 bhp / 650 lb-ft) the supercharger itself needed to be bigger since the output of a positive displacement supercharger is proportionate to its size. The Callaway GenThree supercharger is 32% larger in displacement (2300cc vs 1740cc). Cooling - Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature associated with forced induction.
