2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

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.

Here's why you don't want the 2016 BMW M4 Clubsport

BMW Spain recently announced a special-edition M4 Competition Sport. It's billed as a more comfortable version of the M4 GTS (including rear seats) and, with only 60 copies available, will be more rare than that hardcore M4. But hold on a second because the CS is not exactly the unicorn it appears to be. And the closest thing to a CS in the United States might be better. Here's why. The M4 Competition Sport comes with more power, 20-inch wheels, and adaptive M chassis. The twin-turbo six has been turned up to 444 horsepower, which is shy of the crazy 493-hp water-injection version from the GTS. In fact, it's the same power you get with the $5,500 Competition Package that BMW USA announced back in January. And our Competition Package also comes with the wheels and M chassis setup. View 38 Photos We concede one area where the M4 CS does earn our envy. The giant carbon wing on the back and various other carbon-fiber elements do look pretty great, although tacking them on likely does not reduce the vehicle's weight. They're also all available from the vast M Performance catalog, so you could buy an M4 and tack on whichever ones you like best. Lucky Spanish customers also get carbon-ceramic brakes, but we can order those as a standalone option for $8,150. And the M4 CS only comes with a seven-speed dual-clutch automatic. Here in the States you can order all those goodies with a manual. Each of the 60 M4 Competition Sport coupes will sell for 132,900 euros in Spain, which works out to about a 45 percent markup compared to a standard-issue M4 coupe. So no, we don't get the numbered plaque on the center console or the neat seats. But we do get all the rest of it, with a manual, and at a much lower price than the Spanish M4 CS. And you can get the same stuff in the four-door M3. U-S-A! U-S-A! Related Video: Related Gallery 2016 BMW M4 GTS View 65 Photos BMW Coupe Performance bmw m4 bmw m4 gts
