New Ariel Atom 4RR is a 525bhp face-melting track car
Like the regular Atom 4, it's powered by the turbocharged 2.0-litre four-cylinder petrol engine from the Honda Civic Type R. But for the 4RR, Ariel has added revised internals and new components, as well as upgrading the oil and fuel systems, allowing the motor to spit out 525bhp and 550Nm of torque.
That's more than four times as much power as the original Ariel Atom produced from its Rover K-Series engine, and even the Ariel Atom V8 – which used a bespoke 3.0-litre V8 – had 'just' 475bhp on tap. In fact, the Atom 4RR has more power than the latest BMW M3, all of which is sent to the rear wheels – as has always been the way with the Atom – while the car will still weigh less than 700kg.

Ariel hasn't announced any exact weight or performance figures for the Atom 4RR just yet, however considering the 400bhp Atom 4R tipped the scales 665kg and could do 0-62mph in 2.7 seconds, we think the new model might pull off the sprint in 2.5 seconds or less.
Similarly, we're assuming Ariel has made other changes for the Atom 4RR beyond just bolting in the more powerful engine, because the car is claimed to 'enable the most serious track drivers to explore the limits of the lightweight Atom, while utilising the full extent of their driving skills'.
More technical details will be released later in the year, as will the price tag. But we know that only 25 examples of the Ariel Atom 4RR will be produced, and all will be made to order.

Toasting 50 years of the Lotus Esprit with... a garden party?
'Dad was always looking forward. He saw what other companies were doing and wanted to raise Lotus's game,' he replies. 'We had gone from the Elan to the Esprit, but this extraordinary car still had (the Elan's) handling characteristics… so you had your foot in both camps.' Wandering around the gathered Esprits gives you a measure of how Lotus sweated the model for all it was worth with, by my reckoning, 22 derivatives produced during its life – possibly even more. As well as the S1s, all the models from different designers are represented – X180 (Peter Stevens), S4 (Julian Thomson) and last-of-line V8 (Russell Carr) – plus special editions like the black and gold Esprit JPS and blue, red and silver Esprit Essex, both referencing Lotus's F1 ties. And what do we find in the manor's swimming pool? Naturally, James Bond's Esprit sub – aka 'Wet Nellie' – from the 1977 film The Spy Who Loved Me. In fact, it's what looks to be a half-scale model, with the actual full-sized prop at the poolside, in front of the Turbo Esprit from the 1981 Bond film For Your Eyes Only. As I leave the event, heads are turned towards Giugiaro, who is now sitting in an S1 parked next to Lotus's 2024 Theory 1 concept car. In 50 years' time, I only hope that car will prove as influential to Lotus's future as the Esprit was in 1975.

How Coventry's sewers starred in The Italian Job
A stretch of sewage pipe underneath Coventry cemented its place in British film history, thanks to a legendary car chase, a French stuntman and a much-loved motoring icon, the the late 1960s, while producing what would become the classic crime caper, The Italian Job, the filmmakers were could not find a suitable location in Turin, Italy, to film part of the famous escape through the streets of the city and its as Oscar-winning producer Michael Deeley recalled, luck intervened: "It was completely by chance we discovered a stretch of pipe in Stoke Aldermoor." That find led to the classic scene and, decades later, the exact location, now buried underground, is being tracked down and the story retold by the BBC's Secret Coventry series. In the heist movie, after stealing a shipment of gold destined for a Turin car factory, the robbers make their escape with the gold in three drive down steps, leap across gaps between buildings and go through the for the latter part, they needed a wide enough section of sewer pipe which, as Mr Deeley said, they found in 240m (262yd) long pipe was being installed at the time and snaked under part of Stoke Aldermoor, between The Barley Lea and Allard from the time show the Minis being lowered down to the pipes which were already being buried underground. Neville Goode was the operator of the crane and still remembers the day clearly - though at the time, he had no idea his work was part of film history."It was just putting the cars down the tunnel, no idea why. Nobody told us why it was being done," he later, after seeing the film, did the reality sink in: "We thought, 'Hang on, I remember working on that film'."Kevin Conway, a Mini enthusiast, was the driving force behind the installation of a commemorative plaque at the scene in 2019."They arranged for some local cameramen to be able to lower the Minis into the ground and it turned out to be one of the greatest British films ever made," he said. Star Michael Caine was not needed for the Coventry filming, but the daredevil behind the wheel in the tunnel was French stunt star Remy Julienne, who orchestrated much of the film's attempted to achieve a full 360-degree roll of the car inside the sewer, but Mr Conway said it ended up that Julienne "crashed a few times"."[Neville] had to take a smashed Mini out of the tunnel, on its side, drag it out and lift it out," he added. But the retired crane operator did come to the stuntman's aid through a pair of gloves lent to the Goode said: "Julienne came out and said there was too much water, it was making the steering wheel slippy so I said, 'I've got a pair of gloves in my cab if you'd like to borrow them, maybe they would help?'"So he took those and he kept them."The area above the sewer pipe and the plaque at the spot, installed six years ago, has become a surprising landmark among fans of the film, Mr Conway said."The amount of people that I meet…it's popping up on Facebook: 'Here's me standing beside it'," he added."Ten feet underneath where that plaque is, was where Remy Julienne sat in the front seat of a Mini and gunned his engine."
