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.

This SEMA special drag race is absurdly awesome

The SEMA Show came and went last month, and it showed us a ton of heavily modded goodies to dream about during the long, cold winter. The Motor Trend Channel on YouTube is keeping the party rolling a little longer, though, with a drag race inspired by the aftermarket event. All of the hosts were supposed to borrow a vehicle from the show for the big race, but only two of them actually cajoled companies into lending their wares. Still, the result includes four very cool and extremely different examples of the breadth of the automotive hobby. First up, there's a 1955 Chevrolet with a 535-cubic-inch (8.8-liter) Hemi V8 stuffed under the hood. Appropriately, it's dubbed the Blasphemi, and with skinny tires up front, fat rubber in the rear and a stripped interior, this this is made to go very fast in a straight line. Next, there's a stock Dodge Challenger SRT Hellcat boasting 707 horsepower. Plus, host Jessi Lang has her dog riding shotgun for the race. A Chevy Sonic RS with some body mods, downpipe and intake is also competing. Finally, the most bizarre of the quartet is a custom 1958 Jeep Forward Control with a 5.7-liter Hemi V8 and treads to replace the wheels. Obviously, the Blasphemi and Hellcat are the only two that really have a chance of winning, but check out the video to see which one crosses the finish line first.

GM recalls select Tahoes, Yukons, Escalades for rear driveshaft issue

GM is recalling a number of its full-size SUVs due to an issue with the rear driveshaft assembly that could ultimately result in driveshaft failure. The actual number of total vehicles involved in the recall is small at just 1,789, but it’s spread out across the entire 2021 model year full-size GM vehicle lineup. That means a small number of every model is being recalled, including the Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL and the Cadillac Escalade and Escalade ESV. GM traced the issue back to certain driveshaft assemblies with ball bearings that were not properly heat treated. If theyÂ’re not properly heat treated, GM says that the balls may deform over time, causing noise and vibration. Continue to drive in this condition, and GM says the affected joint in the driveshaft assembly could seize, causing loss of drive power. However, the problem wonÂ’t present itself all at once, as GM says there will be a gradual increase of noises and vibrations before total failure. For those few owners with affected vehicles, GM says that it will replace the left and right rear driveshaft assemblies with properly-built units. Per usual with recalls, this will be done at your local dealership at no cost to the owner. If you have one of the recalled SUVs, expect to be notified mid-March. Related video:
