2015 Rolex 24 at Daytona pre-race notes

Reigning Indy 500 champion Ryan Hunter-Reay summarized our feelings on every year's Rolex 24 Hours at Daytona when he said, "The 24 kind of kicks off the year and has become part of my calendar... It definitely helps you get in race shape after a long layoff." Speaking of IndyCar drivers, 14 of the 33 pilots who started last year's Indy 500 are driving in Daytona this year, and an IndyCar driver has been part of the overall winning team for the last four years. The race starts at 2:10 pm Eastern Standard Time, here's where you can watch it: 2-4 pm: Fox Sports Network 4-8 pm: Fox Sports 2 8-10 pm: Fox Sports 1 10 pm-7 am: IMSA TV on IMSA.com - commentary available here for the full 24 hours 7 am – 2:30 pm (Sunday) – Fox Sports 1 Timing and Scoring Andy Blackmore's typically awesome Spotter's Guide Video primer on the four classes: Prototype (16 in this year's race), Prototype Challenge (8), GT Le Mans (10), GTD (19), and how to identify them. Daytona International Speedway: tri-oval with an infield road course, 3.56 miles long, 12 turns Entry list Qualifying results We've tagged along with Audi for the 53rd running of the race, which marks the first event in the Tudor United SportsCar Car Championship. After a difficult first year of teething – IMSA president and COO Scott Atherton said, "Everybody on our staff and everybody that raced with us last year would tell you it was the most challenging season on record" – some things are smoother this year, some things aren't, starting with the field: 53 cars are expected to line up, 14 fewer than last year, the smallest field since 48 cars lined up in 2011. The Prototype class shed three teams from 2014 and the GT Daytona class lost ten, so there's a 19-car field in that class (nine Porsche 911 GT Americas, three Ferrari 458 Italias, two each of the Aston-Martin V12 Vantage, Dodge Viper SRT, Audi R8 LMS, and one BMW Z4). Truth be told, last year's number was probably inflated by having the previous American Le Mans Series and Grand-Am Rolex Sports Car Championship combined to make the USCC; the field in 2013 was 57 cars, in 2012 it was 59 cars. Another factor in this year's race is that the GT class adopts FIA GT3 rules from next year. Brad Kettler, manager of Audi's customer motorsport program, said they'd sold five R8 LMS cars last year but zero for this year – there are undoubtedly teams waiting on the sidelines for the rules unification before spending the money.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

Audi R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:
