The Corvette ZR1 Just Put Down a Crazy Number on a Dyno
The
Chevrolet Corvette ZR1
carries the honor of being the most powerful Corvette ever... at least until the
ZR1X
hits production later this year. Customers are finally starting to receive their cars, so it was only a matter of time before a ZR1 showed up at a dyno for a run. The results are even more impressive than we expected.
Paragon Performance
in Waukee, Iowa, managed to secure a totally stock ZR1 for a run on its floor-mounted dyno to see exactly how much power the supercar-killing 'Vette throws to the wheels. As a reminder, the twin-turbo 5.5-liter V-8 is officially quoted at 1,064 horsepower and 828 pound-feet of torque at the crank.
If you know how cars work, you'll know there's inevitably some power loss as torque travels from the crank, through the transmission, through the differential, and to the wheels. In theory, we should expect a noticeable loss in power in the dyno readings. Except that doesn't happen. In the last dyno run, the ZR1 puts up a reading of 1,028 hp and 839 lb-ft of torque to the wheels.
If you factor in drivetrain losses of around 10 percent, this means the ZR1 is actually making closer to 1,180 hp and 920 lb-ft of torque at the crank. That means Chevy is heavily underrating the twin-turbo V-8's real performance. In all likelihood, the factory rating applies to the engine in the most grueling scenarios, like driving through Death Valley or being pushed to its limits on a race track.
That means at worst, the engine will at least make 1,064 hp, no matter what. But if you're in a nice, cool dyno room with lots of clean air and no load, you'll make closer to 1,200 horsepower. We can only imagine how the ZR1X will perform on a dyno.

Would You Boogie With This Chevy Van?
Read the full story on Backfire News Far from your average Chevy G10, this van has been customized to look like a shag-carpeted ride from back in the day. But the crazy interior touches were recently done, as was the innovative idea of putting the sliding door on struts so it lifts up dramatically, even if that's not practical for parking lot though we wouldn't stop to consider this thing, we also know some people will think they've died and gone to heaven. The blue shag carpet is… something. That's paired with red leather or vinyl that's tufted with buttons for even more of a throwback appearance. But wait, there's more, plenty more. For some reason, the rear cargo area has a sink and cabinet, then a partition with a single step that allows you to climb into what we assume is supposed to be a sleeping quarters of some sort. Yes, technically you could live in this thing with its natural exterior patina. Just expect as you drive through neighborhoods people will watch you suspiciously. Apparently, under the elevated section are storage drawers. There are plenty of LED lights throughout the interior, perfect for lighting things up as you're parked down by the river for the night. This boogie van will get moving with a 350ci V8 nestled between the front seats. The owner says it has a new Edelbrock Performer chrome intake manifold, plus new spark plugs. Power is channeled through a TH350 transmission. Plus, there are cool ankle-burning side pipes to give this van that extra pop, which will impress all your house guests for sure. Imagine yourself living out of this van, or maybe just using it for epic road trips. Maybe this is your dream ride? Check out this Chevy's listing here. Images via Jeff Ferguson/Facebook Marketplace

Tesla's Robotaxi service has its first reported 'safety concern'
Austin reported a "safety concern" with a Tesla Robotaxi. The incident occurred on East Oltorf Street, according to the city's autonomous vehicle incident dashboard. Tesla's Robotaxi service began on June 22, with 10 to 20 vehicles and safety monitors. Austin reported its first incident with a Tesla Robotaxi service, according to the city's autonomous vehicle incident dashboard. The safety concern was reported to have occurred on June 22, the same day Tesla launched the service. It took place on East Oltorf Street in downtown Austin, according to the dashboard. According to the transportation department, the safety concern was reported by Edward Niedermeyer, who has previously been critical of Tesla. Niedermeyer shared a YouTube video that he said showed a Tesla vehicle braking "hard twice for stationary police vehicles outside its driving path." Niedermeyer and a spokesperson for Tesla did not immediately respond to requests for comment. The dashboard tracks safety concerns and issues, such as collisions or near misses, involving autonomous vehicles in the city. The dashboard also shows incidents with other self-driving companies, including Waymo and Zoox. It has detailed 120 incidents over the past two years and 45 in dashboard relies on reports from city departments and its 311 service rather than direct monitoring. The city says the data is unvalidated and may miss incidents citywide. A spokesperson for the National Highway Traffic Safety Administration previously told Business Insider that the agency was in contact with Tesla regarding the company's autonomous vehicles. Tesla launched its robotaxi service to a select group of users. Elon Musk has said the launch would begin with between 10 to 20 robotaxis. Currently, robotaxi rides include a safety monitor who sits in the passenger seat and remote operators who can intervene when needed, according to videos of Tesla's robotaxi service posted online.

This 2025 Corvette ZR1 Made 1028 HP At the Rear Wheels in a Dyno Test — And It's Stock
With an official output of 1068 horsepower and a top speed of over 230 miles per hour, the new C8-generation Chevrolet Corvette ZR1 is a truly ridiculous machine on paper. (And, as we found during our first drive test, a surprisingly easy-to-drive one in practice.) A recent dyno test conducted by the YouTube channel Paragon Performance, however, suggests that the car's real-world numbers may be even more absurd than what General Motors claims. In a dyno test streamed live on Tuesday, the channel found that the C8 ZR1 produced an astounding 1028 hp and 840 lb-ft of torque at the rear wheels. Since the car is officially rated for 1064 hp and 838 lb-ft of torque, that number either suggests an incredibly efficient drivetrain or a substantially underrated engine. As number would suggest just a 3% drivetrain power loss, and the oft-quoted 15% power loss through the drivetrain would make the actual power output 1193 hp, the truth is likely somewhere in between. Paragon Performance says it has two new ZR1s, and plans to run additional tests over the next week before releasing another video. That should account for some of the possible variances in dyno testing, which could eventually show that this was just a particularly good day to run the Corvette. Nevertheless, reaching 1038 hp at the wheels is a staggering achievement for any road car. If the official rating of 1064 hp is actually a conservative estimate, it would mirror the first estimates of the car's top speed. GM first announced that the ZR1 could reach a top speed of "comfortably over 215 mph" when the car debuted. Four months later, the brand revealed that it had tested the car's V-max and found that it could actually reach 234 mph. No matter how powerful the ZR1 actually is at the crank, it is certainly the most powerful production Corvette ever ‚ but it will not hold that record for long, because the hybrid ZR1X is following closely behind with an additional 186 hp from an electric motor on the front axle. Because both ZR1 variants use the same turbocharged engine, this dyno run suggests great things for that car. If the ZR1 is really more powerful than GM's official numbers, the ZR1X should be, too.
