2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

2013 Mercedes-Benz GLK250 Bluetec gets 33 mpg, priced from $38,950*

It's been more than a year since we first saw the 2013 Mercedes-Benz GLK250 Bluetec unveiled at the 2012 New York Auto Show, but it looks like the compact diesel crossover is finally starting to roll into dealerships. Those wanting to buy a diesel GLK will only have to pony up an extra $1,500 over a base, gas-powered GLK350, as the GLK250's starting price is listed at $38,590 (*not including $905 destination charge).
The turbocharged 2.1-liter four-cylinder diesel produces 200 horsepower and 369 pound-feet of torque, and Mercedes-Benz has also provided some fuel economy numbers for this model, with claimed EPA estimates of 24 miles per gallon city and 33 mpg highway. There is no listing for the GLK250 on the EPA's website yet, but the figures represent significant increase over the GLK350's lackluster 19 mpg city and 25 mpg highway figures, which are for the rear-wheel drive model. The GLK250 comes standard with the 4Matic all-wheel-drive system - a $2,000 option on GLK350 - meaning that if you want an all-wheel-drive version of the 2013 GLK, it's actually cheaper to opt for the diesel model.

The 2016 Spanish Grand Prix flipped all the scripts

The Monaco Formula 1 Grand Prix circuit and the Hungaroring fly the flag for processional races, yet Spain's Circuit de Catalunya is arguably as bad. Before this weekend, the pole-sitter won the race 19 times out of the last 25 years. The front row of the grid produced 23 winners in the past 25 years. The racing gods edited that script this year, when a first-lap crash and two mid-race strategy changes kept things open until the end of the 66-lap race. It started when Mercedes-AMG Petronas teammates Nico Rosberg and Lewis Hamilton took each other out on Lap 1. After Rosberg passed pole-sitter Hamilton into Turn 1, Rosberg's car slowed through Turn 3, somehow in the wrong mode. Hamilton closed in on Rosberg so quickly that once the Brit ducked inside for the pass, he couldn't back out. Rosberg, however, closed the door so suddenly that Hamilton had no choice but to drive onto the grass. When Hamilton spun, he collected Rosberg and both Mercedes' ended up in the gravel trap. The stewards deemed it a racing incident. The crash put Red Bull teammates Daniel Ricciardo and Max Verstappen in the lead, followed by Toro Rosso driver Carlos Sainz and the Ferrari duo of Sebastian Vettel and Kimi Raikkonen. Both Ferraris cleared Sainz by Lap 10, leaving 56 laps for them to haul in the Red Bulls. Ferrari loosely followed Red Bull's pit strategies. Ricciardo pitted on Laps 11 and 28, Vettel pitted on Laps 15 and 37. Verstappen pitted on Laps 12 and 35, Raikkonen pitted on Laps 13 and 36. Pirelli predicted a three-stop race as the fastest and that the medium tire could only go about 23 laps. Verstappen and Raikkonen didn't get those memos. So while Ricciardo and Vettel came in for third stops the Dutchman and the Finn stayed out, with Verstappen ahead of Raikkonen at the front of the race as of Lap 43. That's when Verstappen – 18 years and 227 days old – proved how good a driver he is, lapping perfectly as second-place Raikkonen closed the gap to a little more than half a second. The Finn still couldn't get past the Dutchman down the pit straight even with the help of DRS, nor under braking at the only real passing opportunity into Turn 1. At the end of Lap 66 Verstappen crossed the line ahead of Raikkonen, a victorious end to Verstappen's first race weekend after being promoted to Red Bull. Further back, Vettel and Ricciardo fought for scraps, the German staying ahead to finish third.
