Five awesome Lego car creations

Lego cars are among our favorite toys. They're fun for play, and if built properly, great to display. With that in mind, we've crafted a list of some of the best creations we've seen. Some are on sale now, while others are merely the work of fanciful enthusiasts. There are even a couple that you definitely cannot buy (we'll explain).
Our choices are diverse, including everything from a diminutive 1969 Chevy Corvette to a fullsize Ferrari Formula One racecar. These are just five projects that caught our eye - there are many more out there - so if you don't see your favorite Lego car on the list (or if you have your own creation), please tell us about it, in Comments.

GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.

Cadillac ATS to go racing in 2015 as CTS.V.R replacement

Cadillac has been racking up victories with the CTS.V.R in Pirelli World Challenge racing for two model generations now, including recent GT class championships in 2012 and 2013. However, even winning racers eventually have to retire, and it looks like the CTS may be taking a bow at the end of the season. In its place, Caddy is reportedly working on a new racecar based on the ATS Coupe, and it might even get to compete internationally.
According to Racer, Pratt & Miller Engineering is leading the development and is already lapping the ATS racecar in Michigan for testing. It reportedly drops the CTS' V8 in favor of a twin-turbocharged V6 powering the rear wheels. Since this is the same team behind the hugely successful Corvette Racing program and the current CTS.V.R, the latest car appears to be in good hands.
The new model would also adhere to GT3 rules, according to Racer, and that might signal a big change for Cadillac's motorsports program. It means that the ATS could be sold to teams in the numerous series around the world that accept these vehicles. That would broaden the luxury coupe's exposure and put it up against GT3 racecars from premium brands, like Bentley, Porsche and McLaren. If it wins, the change could be a marketing bonanza for the brand.
