Mercedes F1 to use Qualcomm 5 GHz WiFi for its tire data

In Formula 1 you need more of everything. More speed, more grip, more hospitality, more money. And you need data, reams and reams of data. The Mercedes-AMG Formula 1 team – the guys with the silver cars driven by 2015 F1 champion Lewis Hamilton and his teammate Nico Rosberg – need so much information that they've teamed with Qualcomm to wirelessly upload thermal imaging data of its tires. During a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Live telemetry has been a feature of Formula 1 for 20 years, though there are more restrictions on it than in the past. (In the days leading up to last weekend's United States Grand Prix in Texas, Formula 1 major domo Bernie Ecclestone said that F1 needs to cease being an engineering war and return more responsibility to the drivers.) Nevertheless, F1 teams gather vast amounts of data during a race weekend, particularly in practice sessions during which restrictions on what they can upload from cars – from engine/power unit parameters to aerodynamic loads – are less prohibitive. For example, during a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Mercedes F1 technical director Paddy Lowe points out that the standard telemetry system simply doesn't have the bandwidth to handle the thermal tire imaging data that the onboard thermal cameras generate. Why do you want a thermal video of the tires? Because it tells the engineers and drivers precisely how much temperature there is across the surface of a tire during a lap, in corners and on the straights. It also indicates how quickly the tires come up to temperature and when they potentially overheat. Understanding the temperature variations allows the team to set the cars up optimally for grip and tire life during a stint. Qualcomm's system works with the race cars like this: Each car has forward- and rear-facing cameras in a winglet mounted on the left side of the engine intake behind the driver's head, which continuously record thermal images of the tires. As a Mercedes enters the pit lane, it passes a Qualcomm 802.11ac WiFi receiver to which it uploads the thermal data. As the car nears the garage, another receiver takes over the upload. Several Qualcomm Snapdragon 805 processors crunch the raw data as it uploads. The data is encrypted – there are always prying eyes in Formula 1.

Mercedes-Benz recalls 3,800 total vehicles in two campaigns

Mercedes-Benz is recalling 3,813 vehicles in two campaigns in the US, and the affected models span the top and bottom of the brand's product range. The larger recall covers 2,956 examples of the 2014 S63 AMG sedan and 2015-2016 S63 AMG 4Matic sedan and coupe. According to the National Highway Traffic Safety Administration, a software error in the engine control unit can cause the high-performance luxury cars to stall when coasting to a stop. While this can initially appear to be normal operation of the stop/start system, the engine doesn't restart when the driver releases the brake pedal. Getting moving again involves shifting into neutral or park and going through the ignition process. The repair campaign will begin on December 8, and the models will need an update to the engine control unit software. This will also be the second recent recall for the 2015 S63 AMG 4Matic Coupe because another fix will replace their seatbelts. In a more complicated issue, Mercedes is recalling 857 examples of the 2015 CLA250, CLA250 4Matic, GLA250, GLA250 4Matic, and the 2016 SLK300 because a weld on the camshafts might be in the wrong place "due to a production deviation at a supplier." Potentially, the important parts could break and damage the engine. Beginning November 30, dealers will replace the affected camshafts as a precautionary measure. RECALL Subject : Engine Stall due to Engine Control Unit Software Report Receipt Date: OCT 14, 2015 NHTSA Campaign Number: 15V652000 Component(s): ELECTRICAL SYSTEM , FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 2,956 All Products Associated with this Recall Vehicle Make Model Model Year(s) MERCEDES BENZ S63 AMG 2014 MERCEDES BENZ S63 AMG 4MATIC 2015-2016 Details Manufacturer: Mercedes-Benz USA, LLC. SUMMARY: Mercedes-Benz USA LLC (Mercedes-Benz) is recalling certain model year 2014 S63 AMG sedans and 2015-2016 S63 AMG 4Matic sedans and coupes manufactured May 14, 2013, to September 18, 2015. In the affected vehicles, due to a software error within the engine control unit, the vehicle may stall when coasting to a stop, such as at a traffic light. CONSEQUENCE: The vehicle stall may be interpreted by the driver to be a planned shut-down as part of the ECO-Start-function. However, the engine will not restart automatically after releasing the brake pedal, immobilizing the vehicle and increasing the risk of a crash.

2015 MV Agusta F4 RC superbike debuts with AMG livery

MV Agusta, the Italian motorcycle maker with 37 Constructors Championship trophies earned in Grand Prix racing, returned to the World Superbike Championship for the 2014 season. With one annual campaign under its belt, it has released the customer version of its racing superbike, the F4 RR. The street-legal version will come in two power levels depending on the exhaust: either 205.5 horsepower with the standard exhaust, or 212 hp with the 4-2-1-2 Termignoni race exhaust. At 386 pounds dry, the RC is about 33 pounds lighter than the World Superbike entrant, but it's still heavier than the competition from Aprilia, BMW, and Ducati. It is, though, a little more powerful than all of them in its full-fat guise. Compared to the RR, MV Agusta made changes to the RC that include a new cylinder head, crankshaft, and camshaft, larger fuel injectors and lighter pistons, a lithium-ion battery, and magnesium casings. Titanium connecting bolts affix a carbon fiber fairing done up in the AMG livery of the World Superbike ride. If you want one, act quickly and come strong: only 250 will be produced, at $46,000 a pop. If you're not that keen, there's a high-res gallery above.
