Mercedes CLA45 AMG Racing is ready for a spot on the grid

Mercedes-Benz trotted out its CLA45 AMG-based racer at the 2013 Frankfurt Motor Show. We first showed you the sedan in the deluge of news and reveals that precedes most good auto shows, and were blown away by the car, formally known as the CLA45 AMG Racing Series.
We were strolling by the Mercedes stand, and figured we'd pop in and take a look at the new racer and its carbon-fiber body panels, gutted interior, and race-sourced aero parts. It's a looker, both as a road car and a track weapon. It's not clear what series the CLA45 AMG will qualify for, although it does seem like a shoe-in for the World Touring Car Championship. Let us know what you think of the CLA racer down in the comments. In the meantime, we've got a full gallery of live images up top, along with the stock images that were posted last week on the Mercedes-Benz Facebook page.

The Vision Mercedes-Maybach 6 is pure electric excess

The Vision Mercedes-Maybach 6 is a two-door, two-passenger coupe that spans over 18 feet long. Everything about this car is more than you need. But isn't that the true definition of ultimate luxury? With so much sheet metal, it can be tricky to get everything to look right, but Mercedes seems to have done nicely with this concept. Overall, the car's long nose and short deck are reminiscent of the Mercedes-AMG GT, and the long, tapering tail and lights are similar to that of the Mercedes-AMG Vision Gran Turismo concept from a few years ago. Capping off the front of the Mercedes-Maybach 6 is a proud, prominent grille that the company claims was inspired by a pinstripe suit. At each corner are 24-inch wheels with transparent panels based on the transforming, aerodynamic wheels of the Concept IAA Mercedes previously showed. Powering this massive coupe are four electric motors that can produce a combined 738 horsepower. Mercedes says that will be enough to get the car to 62 mph from a standstill in under 4 seconds. The motors are backed by an 80 kWh battery that the company says can propel the car up to 200 miles. Perhaps more interesting than its range is the fact that the Mercedes-Maybach 6 can pick up a charge worth 62 miles in just 5 minutes, assuming you've got the right charger. This is technology that could really make a difference in the day-to-day practicality of electric cars, provided that it makes it to reality. The car can be charged either by being plugged in, or wirelessly with an inductive charging system. Inside, the Vision Mercedes-Maybach 6 has even more fantastical features. It does retain analog gauges as a link to the past, but augments them with wrap-around glass trim that doubles as a display and touch-sensitive interface. The windshield seems to be pulled from Mission Impossible with its ability to display information. Sensors in the seats are designed to read the condition of the passengers and even their outfits to custom tailor everything from lighting to massage features. It's hard to say what the production odds are for this mega Mercedes, but you probably shouldn't hold your breath. Even for the rarified segment of seven-figure cars, this would be pretty extravagant. It wouldn't be impossible, or without precedent. Back when Maybach was still its own brand, the company created a ridiculous luxury coupe called the Exelero, and they sold the fully-functional car.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
