2015 Mercedes-AMG C63 S First Drive [w/video]

As I mashed the throttle heading into the back straight of a nearly three-mile-long race track, I couldn't help but center my mind on two ostensibly disparate subjects: physics and pistons. If the heart of an automobile is its engine, the heart of the engine are its rotating bits – the crankshaft, pistons and the block they're nested inside. It seems fitting, then, that the internals of the twin-turbocharged 4.0-liter V8 typify the brand-new 2015 Mercedes-AMG C63 sedan I found myself piloting in Portugal. Whereas the last C-Class AMG availed itself of a brute of an engine, employing 6.2 liters of displacement to make its 451 horsepower the old fashioned way, the latest AMG's V8 engine has been downsized radically. I had the opportunity earlier in the day to actually hold the pistons of the new 4.0 Biturbo V8 in my hands, alongside those of the outgoing 6.2. The difference in size is staggering, the new lumps looking downright picayune in comparison to the latter. These eight seemingly diminutive pistons turn combustion into crankshaft-spinning power inside a block that is smaller, lighter and more compact than I'd have thought possible, considering the prodigious output the engine spits out. I had gone into this assignment expecting to pen an ode to lost love; a sonnet of sorrow bemoaning the switch from massive cylinders to wheezing power adders. But I was wrong. In fact, the report that follows may indeed read a little like a love song, except it will heap praise not on what used to be, but instead on what is now possible. The new heart of AMG more than makes up for its reduction in size by relying on turbochargers and smart engineering to turn just 4.0 liters into 469 horsepower and 479 pound-feet of torque starting at just 1,750 rpm, or as much as 503 ponies and 516 lb-ft in uprated S guise. Foot to the floor, eyes focused on the turn ahead, a hard right-hander named Primeira that requires hard braking and quick reflexes, I had a fleeting moment of clarity: These are some hard-working pistons. A few days on the street and track in and around Faro, Portugal, has convinced me that the new Mercedes-AMG C63 is a better car in any meaningful measurement than it was before. And I'll go one step further. Not only is this the best C-Class AMG ever, it's also my new favorite in the hotly contested segment that includes such knee-benders as the BMW M3 and M4.

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.

Average new-vehicle transaction price hits a whopping new peak in December

Elevated prices for products and higher borrowing rates led to record high transaction prices for new vehicles in December, with the average cost in the U.S. rising to a record $49,507, according to data from Kelley Blue Book released today. The report notes that ATPs — average transaction prices — have climbed above suggested retail prices — MSRPs — for more than a year. Sales volumes were up in December on a year-over-year basis by more than 5%, a situation Kelley attributed to improved supply. Overall sales for 2022, however, were off 8% year over year. “The transaction data from December clearly indicates overall prices showed no signs of coming down as we headed into year-end,” said Rebecca Rydzewski, research manager of economic and industry insights for Cox Automotive. “Luxury prices fell slightly in December, but non-luxury transaction prices were up. Truck sales were particularly strong last month, and with many trucks selling for more than $60,000, a new record was all but inevitable.” Industry analysts claim the most obvious headwinds in the new car market are generated by higher interest rates, forced by the Federal Reserve's rate hikes intended to tame inflation, and by generally limited inventory. A recent report from J.D. Power showed that the average monthly payment for a new vehicle loan in December was $718, up $47 from a year ago. But 16% of consumers in December took out loans with monthly payments of over $1,000. Consumers think vehicles, and electric vehicles especially, are way too expensive. Fortunately, manufacturersÂ’ incentives, all but extinct in the past two years, are returning, especially in the electric-vehicle and luxury market, the Kelley data suggest. Plus, "With the new tax credits on the way, electric vehicle ATPs will drop lower for qualifying vehicles,” Rydzewski said. Non-luxury brands, such as Honda and Kia, showed particularly strong performance in December, with the average price paid at $45,578 — a record high and an increase of $994 month over month. Meanwhile, the average luxury buyer paid $66,660 for a new vehicle last month. Mercedes-Benz and Land Rover showed the most price strength in the luxury market, transacting between 2.6% to 6.5% over sticker price. But luxury brands Audi, BMW, Infiniti, Lexus, Lincoln, and Volvo showed the least price strength with some discounting in effect, selling 1% or more below MSRP in December, according to the survey.
