Erebus Motorsport Mercedes E-Class V8 Supercar completes the field [w/videos]

Ford, Holden and Nissan introduced their V8 Supercar challengers a while back. Erebus Motorport, whose racing program got the green light not even 120 days ago, has finally shown off the Mercedes-Benz E-Class racer that will complete this year's field of entries. The first AMG race car ever to be built outside of Germany, it's an Australian-built tube-frame chassis specced to the series' Car of Tomorrow rules, fitted with body panels that channel the E63 AMG.
Supported by AMG Customer Motorsport, the 5.0-liter engine is provided by HWA in Germany, the racing arm of AMG. Regulations dictate that it have roughly 650 horsepower, a redline between 7,000 and 7,500 rpm and a torque curve that matches the parity baseline set for all cars.
Lee Holdsworth, Tim Slade and Maro Engel will drive the three team cars, each with different sponsors. Their first showing will be at the Clipsal 500 on March 3 in Adelaide, here in the US we'll get to see them in May at the Circuit of the Americas. Check out the videos below of the Erebus car starting up at its launch, and footage of all of this year's cars doing pre-season testing on track together.

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.

Audi RS3 Sedan coming to America with over 400 hp?

The Mercedes-Benz CLA45 AMG is a fast, competent car. It's significantly sharper than the Audi S3, and it should be, since its starting price is around $7,000 more. Still, getting walloped by the higher-performing CLA45 AMG must irk some people at Audi, we'd think, which might explain why there are rumors that the S3's big brother is coming to town. Yes, reports are popping up from an Audi of America employee that the Audi RS3 would transition from its Euro-market Sportback body style to a more conventional four-door, and that its styling would be updated in the process. Oh, and it'll have a 400-plus-horsepower, 2.5-liter, five-cylinder turbo with which to bash the four-cylinder AMG. The report comes from Quattro World by way of CarScoops, and goes on to claim that Audi hallmarks like Quattro all-wheel drive and a seven-speed S-Tronic dual-clutch transmission will both be present. The new RS3 Sedan would arrive on US shores in 2017 as a 2018 model, with prices starting between $55,000 and $60,000. That should make Mercedes-AMG very nervous – the CLA45 may start around $50,000, but getting it past the $60,000-range is simple (your author was driving a nearly $68,000 CLA45 just last month, for example). Naturally, we have a call in with Audi of America to see if there's any credence to this report. Stay tuned for updates. Related Video:
