Honda, Chevy reveal low-drag speedway aero for Indy 500

As the two automakers currently participating in the IndyCar Series, both Chevy and Honda were invited this year not only to provide engines to the teams on the starting grid, but to develop their own aerodynamics packages as well. Both revealed their designs for the road-course races a few months ago, but with the Indy 500 approaching at break-neck speed, they've now unleashed their aero approaches for speedways. Both are based on the Dallara DW12 chassis introduced to the series a couple of years ago, but sacrifice some of their downforce at the altar of speed. And you can tell as much from looking at them: both Honda (above) and Chevy (below) have streamlined their designs, with single-plane front wings, lower-profile rear wings and fewer winglets on the body and around the wheels in between. The idea is to allow the cars to reach higher top speeds with less drag, while offering the necessary amount of downforce for the banked turns. With the four opening road-course rounds complete, teams using either automaker's equipment will keep the existing aero kits on their cars for the Grand Prix of Indianapolis on the infield course next week, then switch to the speedway package for the Indianapolis 500 later this month. Then it'll be back and forth for the rest of the season as the circus switches between road courses and speedways. Honda Unveils 2015 IndyCar Super Speedway Aero Kit Apr 30, 2015 - SPEEDWAY, Indiana - To be used at the Indianapolis 500 - Manufacturer seeking 11th Indianapolis 500 victory since 2004 - First public running to take place Sunday at Indianapolis Honda today debuted the "Super Speedway" aero kit of aerodynamic upgrades and components its teams will use at this year's 99th running of the Indianapolis 500. The Honda Super Speedway Aero Kit, produced by Honda Performance Development, Honda's racing arm in North America, includes a variety of individual aerodynamic components fitted to the existing Honda-powered Dallara Indy car chassis. All are intended to give Honda's six Indy car teams – encompassing a potential 17 '500' entrants - the ability to maximize performance at the 2.5-mile Indianapolis Motor Speedway oval and other large ovals ( over one mile in length) on the 2015 Verizon IndyCar Series schedule. "We're excited to unveil our Super Speedway aero kit, the newest element in this era of enhanced manufacturer competition in the Verizon IndyCar Series," said Art St. Cyr, president of HPD.

Honda returning to F1 as McLaren partner

Honda must really love Formula One racing, as evidenced by today's announcement that the Japanese automaker is returning to the world's most popular motorsport for the fifth time in its history. Honda has entered into a team partnership with McLaren to develop and manufacture power systems - the engine and energy recovery system - for the 2015 F1 season. McLaren will be in charge of chassis development and running the day-to-day operations of this newly formed team, which will be called McLaren Honda.
Honda says its decision to reenter F1 racing had to do with new regulations for the 2014 season that require cars to be powered by a 1.6-liter direct-injection turbocharged V6 engine paired with an energy recovery system. Apparently the chance to develop this particular powertrain for F1 racing was too enticing for Honda to pass up, which suggests it has bigger plans for the knowledge learned while developing these systems beyond just winning races.
As mentioned, this is Honda's fifth foray into F1 racing, the first being back in 1964 when it participated as its own team through 1968. Its longest stint came from 1983-1992 as an engine supplier, during which time it partnered with many teams, including McLaren, and won six Constructor Championships. Honda then returned from 2000-2005 as an engine supplier for British American Racing (BAR) before buying that team outright and running it as Honda Racing from 2006-2008. Then the global economic crisis hit. Honda's return to the sport will surely be welcomed by fans as its partnership with McLaren should produce a formidable team. It's a strong signal that the company has returned to health after a few tumultuous years, and hopefully its rediscovered motorsports mojo will help yield more passionately engineered street cars.

Acura NSX bodywork to be sheathed in zirconium e-coat, fewer paint layers

Automakers make halo cars to drum up excitement and show off what they can do, but there's more to it than that. Advanced platforms allow a company's engineers to experiment with all sorts of technologies. And in the case of the upcoming new Acura NSX, that includes new paint processes.
Speaking with Autoline in this video interview, Honda's North American Senior VP Jon Minto talked about an innovative zirconium e-coat which it's applying to the new NSX. Unlike some experimental paints developed for Formula One, however, this coating is not designed to minimize drag or enhance cooling: it's designed to be more environmentally friendly.
It's one of a few measures which Honda is implementing on the NSX before expanding it to more accessible models, along with another process that uses fewer coats to reduce energy consumption by 40 percent. Watch the interview with Autoline host John McElroy right here.
