Emelia Hartford blew up her 2020 C8 Corvette

YouTubers often push the limits of their cars in the name of chasing performance (and viewing) figures, though sometimes these modifications go beyond the limit of the car’s capability, as Emelia Hartford discovered the hard way.

Emelia isn’t the only YouTuber to be running a new C8 Corvette, however she is one of the first to blow theirs up by adding a twin turbocharger setup to the LT2 V8 engine in the C8.

What’s interesting is that prior to destroying the engine on her C8, Emelia explains that the transmission is only rated by GM up to 664 ft-lb of torque. This is a problem, as she openly admits that they have “exceeded [this figure] drastically” – anyone else smell a disaster cooking?

She then goes on to explain that when ‘exotic’ cars such as the C8 are subjected to a twin-turbo setup, they are meant to upgrade the clutch and the transmission to handle this additional power.

Data logging ends in disaster

In preparation for the 1000-mile road rally that Emelia had entered the C8 into, she wanted to run a few ‘pulls’ on the street in order to get some data logged.

On her first launch, it seems that the LT2 V8 wasn’t happy with handling all of the additional power from the twin-turbo setup, despite it appearing initially A-OK as the C8 flew off the line.

After the launch, the V8 developed what Emelia thought to be ‘valve tick’ (often caused by a broken valve) which was a major cause for concern, meaning the data logging session was postponed.

Diagnosing the problem

Arriving back at the garage, further inspection revealed that it was in fact far worse than a bent valve, with a borescope examination revealing that one of the pistons had actually cracked in half. Ouch.

What’s baffling here is that Emelia openly admits that they knew they were pushing the performance of the motor and the transmission. She goes on to say that they knew pushing the LT2 motor so hard was going to result in a ‘bad time – so why not just build it properly in the first place?

So what does the future hold?

Emelia does however say that if they break it, they’ll just build it stronger. With the goal of getting the C8 Corvette to a 9-second quarter mile, they will have to not only replace the broken piston but also upgrade the transmission and a significant amount of the engines internals to handle the power.

Interestingly the comment pinned by Emelia states that “The engine is already in the lab getting stronger. No sympathy needed here. Can’t wait to show you all what’s coming next” so let’s expect to see more of the C8 in the near future.

Self-driving car hilariously crashes into wall during Twitch broadcast

During the Roborace Season Beta event being streamed on Twitch, which pits multiple teams operating “self-driving” cars against each other in an augmented reality experience, one of the cars crashed in an unfortunate, but ultimately hilarious, fashion.

If you never heard of Roborace, you’re probably not the only one. The AI-focused racing experience has only been around for a few years now and while it’s certainly entertaining, it hasn’t quite hit the mainstream just yet in the same way that something like Formula 1 racing has.

Despite this, Season Beta of the aforementioned competition is currently underway and is being streamed on Twitch for the world to see. Of course, it wouldn’t be a race without some spectacular crashes and one happened in an absolutely hilarious fashion on October 29.

During the second day of the Season Beta race, Acronis SIT Autonomous’s DevBot 2.0 car took an abrupt sharp turn directly into a wall immediately after being at a standstill, leading to an unfortunate, albeit hilarious moment during the race.

Unfortunately, the camera cuts away before we can see the reaction of the operators, although it’s hard to imagine that they wouldn’t be a little annoyed at that immediate outcome. While it’s currently unknown what the estimated price is for the DevBot 2.0, as they’re all produced specifically by Roborace, this little crash probably just cost the team a lot of money.

The DevBot 2.0 uses Nvidia’s DRIVE platform to operate, which allows artificial intelligence to take over driving the fully electric car, as it races through an augmented reality track.

As the name suggests, this is the second iteration to use the name and is being used by all teams during Season Beta. It’s unknown whether this error was due to a technical error or was down to the “operators”.

If fans are interested in Roborace, Season Beta is set to continue until October 30, and will be streamed on the competition’s official Twitch channel the whole time.
