A Corvette with 1,250bhp. Not a drag strip special, but a production model. It turns out the 1,064bhp ZR1 wasn't the final boss.
Meet the ZR1X – the long-rumoured hyper-Corvette the internet has previously known as 'Zora' – which combines the ZR1's 5.5-litre, twin turbo V8 with the electric motor and hybrid system from the Corvette E-Ray.

Combined power stands at 1,250bhp. Driving through all four wheels 0-60mph is expected to take less than 2.0 seconds, with the quarter mile dispatched in under 9.0s at a peak speed of over 150mph. Just to be clear, this gives it more power and better claimed acceleration than the 1,183bhp, 2.15s-to-62mph Ferrari F80. Which costs £3.1 million.
The ZR1X is not a limited run car, though. It'll be a full production model sold alongside the rest of the Corvette line-up when it goes on sale later this year. Nor is it an afterthought. According to lead development engineer Keith Badgley: 'It was always part of the C8 plan. We kind of joked about it as our 'kitchen sink car' because we threw everything at it. It was the hypercar we wanted to bring to fruition.'
While the ZR1's twin-turbo V8 has been carried over largely unmodified, the E-Ray's hybrid has been uprated. 'The battery is the same, but we've pushed the architecture so we can use 26 per cent more capacity,' said Badgley. The single electric motor on the front axle now develops an additional 26bhp and 20lb ft over the E-Ray with outputs of 186bhp and 145lb ft.
While the motor sits on the front axle, the 1.9kWh battery and power electronics are sited in the transmission tunnel. It decouples above 160mph, reverting to combustion only for higher speeds. All told the system adds around 115kg of weight to the ZR1, so expect a claimed dry weight of around 1,780kg.

This puts it in a significantly heavier weight bracket than cars such as the 1,525kg F80 and McLaren's 1,400kg, 1,250bhp W1. Traction means it might be able to match them to 60 or 70mph, but above that – and round a track – the Europeans should enjoy a chunky advantage.
Corvette isn't prescriptive about what the ZR1X is for, saying it's aimed at road use more than track use, but has been designed to cope with both. Not many public places you can take it and enjoy more than three seconds of flat-out acceleration, seeing as the ZR1X will be capable of 1.3g peak acceleration and be able to sustain over 1g through third gear. Makes you wonder about the brakes, doesn't it?
On paper those are exceptional. 420mm carbon ceramic discs constructed from continuously woven carbon threads and gripped by 10-piston Alcon calipers. Testing at the Nurburgring they achieved 1.9g deceleration from 180-120mph at Tiergarten.

As with the ZR1, the ZR1X will come in two guises – standard offers a smaller rear wing and Michelin PS4S tyres for a 233mph+ top speed (it's unlikely to have a higher max than the regular ZR1 because of the extra weight), while the ZTK package brings more downforce courtesy of the giant rear wing and Michelin Cup2R rubber.
It'll be available as both coupe and convertible. No word on price yet, but let's guess a $25,000 (£18,500) uplift over the $174,995 (£129,000) ZR1. It might not be priced to rival European exotica, but it has got the performance. Enough to turn this Corvette into a genuine hypercar?

As Musk's 'robotaxi' rollout approaches, Democratic lawmakers in Texas try to throw up a roadblock

A group of Democratic lawmakers in Texas is asking Elon Musk to delay the planned rollout of driverless 'robotaxis' in the state this weekend to assure that the vehicles are safe. In a letter, seven state legislators asked Tesla to wait until September when a new law takes effect that will require several checks before autonomous vehicles can be deployed without a human in the driver's seat. Tesla is slated to begin testing a dozen of what it calls robotaxis for paying customers on Sunday in a limited area of Austin, Texas. 'We are formally requesting that Tesla delay autonomous robotaxi operations until the new law takes effect on September 1, 2025,' the letter from Wednesday, June 18, reads. 'We believe this is in the best interest of both public safety and building public trust in Tesla's operations.' It's not clear if the letter will have much impact. Republicans have been a dominant majority in the Texas Legislature for more than 20 years. State lawmakers and Republican Gov. Greg Abbott have generally embraced Musk and the jobs and investment he has brought to Texas, from his SpaceX rocket program on the coast, to his Tesla factory in Austin. The company, which is headquartered in Austin, did not responded immediately to a request for comment from The Associated Press. The law will require companies to secure approval from the state motor vehicles department to operate autonomous cars with passengers. That approval, in turn, would depend on sufficient proof that the cars won't pose a high risk to others if the self-driving system breaks down, among other reassurances. Companies would also have to file detailed plans for how first responders should handle the cars if there is a problem, such as an accident. The letter asked Tesla to assure the legislators it has met all the requirements of the law even if it decides to go ahead with the test run this weekend. The letter was earlier reported by Reuters. Musk has made the robotaxi program a priority at Tesla and a failure would likely be highly damaging to the company's stock, which has already tumbled 20% this year. Musk's political views and his affiliation with the Trump administration have drastically reduced sales of Tesla, particularly in Europe, where Musk's endorsement of Germany's far-right Alternative for Germany party in February's election drew broad condemnation. Tesla shares bottomed out in March and have rebounded somewhat in recent months. Much of the rise reflects optimism that robotaxis will not only be deployed without a hitch, but that the service will quickly expand to other cities and eventually dominate the self-driving cab business. Rival Waymo is already picking up passengers in Austin and several other cities, and recently boasted of surpassing 10 million paid rides. In afternoon trading Friday, Tesla shares were largely unchanged at $320. ________ AP reporter Jim Vertuno contributed from Austin.

Stubbs: Best tracks for 5 marquee drivers to claim first wins of '25

June 20 - With 16 races of the 2025 NASCAR Cup Series season complete going into Sunday's 400-miler at Pocono Raceway, several stars remain winless as the circuit nears the halfway mark. Here are five big-name drivers who have yet to win this season -- and the track where they're most likely to break through. --Chase Elliott Elliott has been consistent this year, as he sits fourth in points and has yet to finish outside the top-20. But that consistency hasn't translated to race-winning speed very often, as Elliott has only led 95 laps. This is a rare situation where numbers do lie -- statistically, the driver of the No. 9 Hendrick Motorsports Chevrolet has looked the part of a championship contender, but he's failing the eye test. Pocono history: 15 starts, one win (2022), four top-fives, 10 top-10s Track where's most likely to break through: Watkins Glen (Aug. 10) Elliott has won twice before at Watkins Glen, and while his last victory at the New York road course came in 2019, it remains one of his best tracks. Eliott has not won on a road course in the Next-Gen car, but he's finished top-five in both road course races this season. --Tyler Reddick Big things were expected of Reddick after a Championship 4 appearance in 2024, but those expectations are yet to be realized. The No. 45 team has shot itself in the foot several times in recent weeks, and while Reddick is all set to coast into the playoffs on points, it's slightly worrying that he's been unable to get back to victory lane in the 23XI Racing Toyota. Pocono history: Seven starts, zero wins, two top-fives, four top-10s Track where he's most likely to break through: Chicago Street Course (July 6) Reddick was the runner-up in Chicago a year ago and has turned into a fantastic road racer in recent years. Chicago is as big of a wild card as any race on the schedule, but that may be exactly what Reddick needs in order to see the checkered flag. --Chase Briscoe Briscoe's first year at Joe Gibbs Racing has seen its share of highs and lows and his playoff positioning is in jeopardy, but a win would solve that problem. A lack of overall pace hasn't been the issue, seeing as Briscoe won three consecutive poles at Charlotte, Nashville and Michigan, but being unable to put an entire race together has cost the No. 19 Toyota team. Pocono history: Five starts, zero wins, zero top-fives, zero top-10s Track where he's most likely to break through: Dover (July 20) Dover hasn't been great for Briscoe, who doesn't have a top-10 at the track in four starts. But the No. 19 team with Martin Truex Jr. knew how to get around the "Monster Mile," as Truex won at the one-mile oval in 2023 and finished third in 2024. If crew chief James Small can use those notes, Briscoe could snag his first win with JGR. --Ryan Preece Preece and the brand new No. 60 team have put together a solid season so far for RFK Racing. He is only 19 points out of the playoffs going into Pocono, and has shown winning speed in several races this season. With a cut line that will be constantly moving over the next 10 weeks, a win is his best bet -- and his only sure one -- to make the playoffs. Pocono history: Eight starts, zero wins, zero top-fives, one top-10 Track where he's most likely to break through: Richmond (Aug. 16) Short tracks are clearly Preece's best track type, and while Richmond doesn't appear to be a great track for him on the stat sheet, it's probably his best shot to win at a non-superspeedway. --Kyle Busch For the second straight year, Busch is in danger of missing the playoffs. With his winless streak officially eclipsing two full seasons, a win for Busch in one of the last 10 races would be one of the biggest of his career. Pocono history: 37 starts, four wins (2017-19, 2021), 11 top-fives, 18 top-10s Track where he's most likely to break through: Daytona (Aug. 23) It's hard to trust that Busch and the No. 8 Richard Childress Racing Chevy will have winning pace at any track other than the drafting ovals of Atlanta and Daytona. Daytona in particular seems to be a better track for Busch, who had a runner-up finish at the 2.5-mile tri-oval in August 2024. --Samuel Stubbs, Field Level Media
