2016 British Grand Prix kept mostly calm and carried on

Three bursts of chaos decided the course of the British Grand Prix. The first was a literal cloudburst a dozen minutes before the race, which poured water on the Silverstone Circuit while drivers sat on the grid. Six minutes before the lights-out, the race director decided to start the race behind the Safety Car. The field loped around the wet track for five laps. When the Safety Car pulled off, the three leaders – Mercedes-AMG Petronas' Lewis Hamilton, followed by teammate Nico Rosberg and Red Bull's Max Verstappen – stayed out. Behind them, the second chaotic moment occurred: a big group of drivers made pit stops for intermediate tires. When Manor's Pascal Wehrlein spun at Turn 1 on Lap 7, officials issued a Virtual Safety Car. With the rest of the field slowed down, the three leaders ducked into the pits on Lap 8 for intermediates. The fortuitous timing meant all three drivers rejoined the track in their original positions. By Lap 9, with racing resumed, Hamilton had a 4.9-second lead on Rosberg. From that point, even as the track dried, no one bothered Hamilton during what one commentator called "a measured drive." The Brit won his home grand prix, taking the checkered flag seven seconds ahead of Rosberg. Rosberg had to earn second place on track. The German's car didn't respond well to the intermediate tires, so Verstappen excecuted an outstanding pass on Rosberg on the outside through Chapel on Lap 16. After everyone switched to slicks, Rosberg's Mercedes reclaimed its mojo and the German hunted Verstappen down, passing the Dutchman on Lap 38. The final touch of chaos happened when Rosberg's gearbox threw a tantrum on Lap 47 of the 52-lap race. Rosberg radioed his engineer, "Gearbox problem!" His engineer replied, "Affirm. Chassis default zero one. Avoid seventh gear, Nico." The race stewards allowed the engineer's first two statements, but stewards said the instruction about seventh gear contravened the rule that "the driver must drive the car alone and unaided." After the race, officials added ten seconds to Rosberg's time, demoting him to third behind Verstappen. Rosberg's is the first penalty arising from radio communication restrictions. Unsurprisingly, Mercedes will appeal. At this year's Baku race the radio controversy stemmed from engineers refusing to tell drivers what to do. Now we know what happens when the pit wall gets loose lips.

2016 Mercedes-Benz C450 AMG Sport First Drive

A. M. G. Those three letters carry a lot of weight, especially to those who firmly believe that AMG is the hallowed performance pinnacle of the Mercedes-Benz brand. Those purists probably lifted an eyebrow at the front-drive platforms behind the CLA45 AMG and GLA45 AMG, and virtually every AMG-branded SUV that has hailed from the tuner-focused nameplate. But they might want to consider a second look at the 2016 Mercedes-Benz C450 AMG Sport. No, it's not a full-blown, fire-breathing AMG like the C63, and it doesn't get the newfangled "Mercedes-AMG" nomenclature. But after spending some seat time in the C450 AMG Sport, there's a decent chance you'll be quite alright with that. Inside and out, the C450 bears a strong visual resemblance to the mean looking, V8-powered, 469-horsepower C63 and its even fiercer, 503-hp, C63 S variant. The C-Class cockpit feels a bit snugger than you might expect considering its exterior proportions, particularly from the passenger seat. On the other hand, the new C-Class is also quite a bit more nicely appointed than its predecessor, which has inspired more than a few comparisons to the super posh S-Class. As for the C450 AMG, its more purposeful design cues and sportier details lend it a buttoned-down, modern feel. The biggest differentiator between the C and CLA class, however, is the rear of the cabin: the C's back seats are considerably roomier than the entry-level CLA's posterior perches. In place of V8 power, the modest 450 AMG packs a more reasonably endowed twin-turbocharged, 3.0-liter V6 that pushes 362 hp and 384 lb-ft of torque through a 7G-Tronic Plus automatic gearbox (in place of the the C63's dual-clutch seven-speed). Power is routed through all four wheels with a 66-percent rear, 33-percent front torque split. For some numerical context, the C450 AMG exceeds the C400 by 33 hp and the C300 by 121 hp, while it lags behind the C63 by a rather significant 107 hp. Crucially, the six-banger helps shed between 231 and 242 pounds compared the C63 models – this, despite a heavier all-wheel-drive arrangement, as opposed to the C63's rear-drive configuration. The C450 AMG shares a few pieces of hardware with its big brother AMG sibling, including the front axle, electromechanical steering, and upgraded brake setup (though you can't get carbon ceramic stoppers like you can in the C63 S).

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
