500-hp Acura V6 turns this classic 1974 Mini into a mid-engined sleeper

Originally designed on a napkin, the world-famous Mini launched by the British Motor Corporation (BMC) in 1959 was envisioned as a cheap, practical city car for families on a budget. Now, 61 years later, it's a sought-after classic that many aftermarket companies hail as the ideal foundation on which to build their wildest dreams. Gildred Racing thought further out of the box than most by turning a Mini into a mid-engined, 500-horsepower sleeper. Starting with a 1974 model, the California-based firm removed the original four-cylinder engine (and the four-speed manual transmission bolted right under it, where you'd normally expect to find the oil sump) and completely stripped the interior. Only the front seats ended up going back in; the space occupied by the tiny rear bench is now home to a 3.2-liter V6 that started life under the hood of an Acura CL Type S from the early 2000s. It's mounted transversely, and it spins the rear wheels via a six-speed manual transmission. Acura quoted the six's output at 260 horsepower, which would be a healthy upgrade for the little Brit, but Gildred tuned it to 500 horses and 383 pound-feet of torque by making a long list of modifications (including, significantly, adding a supercharger). That's a 466-horse increase compared to a stock 1974 Mini 850, so the scope of chassis upgrades is long. It includes bigger brakes made by Wilwood, and a fully redesigned suspension. And, although packaging a V6 in a small, front-wheel drive car like the Mini was as challenging as it sounds, Gildred pulled it off admirably. The engine bay is now home to the fuel tank and the radiator, while opening the trunk reveals a huge exhaust. The trade-off, of course, is that there's no longer a trunk, but it's a sacrifice we'd happily make. Performance specifications haven't been released yet. Gildred simply said its 1,400-pound Super Cooper is "quite impressive," which we believe. The original wasn't; it took 34 seconds to reach 62 mph from a stop. Gildred also made several changes in the name of modernity. It added a 9.7-inch iPad where you'd expect to find a touchscreen for the infotainment system in a modern car, an Alpine sound system, a push-button ignition, power locks and windows, LED headlights, plus automatic A/C. We imagine the whole cabin gets hot when the V6 works up a sweat. The passengers sit on leather- and suede-upholstered Recaro bucket seats that are heated and cooled.

Meet Vini, the V8-powered second-generation Mini Hardtop

There are several ways to extract horsepower from a Mini Hardtop, and most are far more straight-forward than squeezing a V8 engine under the clamshell hood. And yet, at the request of a client, England-based EDM Racing is well into the process of doubling the retro-styled hatchback's cylinder count while making it rear-wheel drive. Amusingly called Vini, the V8-powered Mini started life as a 2007 Cooper S. It had a little over 100,000 miles on its odometer when David Power, the managing director of suspension bushing expert Powerflex, instructed EDM Racing to prepare it for an improbable engine swap. As mechanics stripped it to the bare metal, Power sourced a 4.0-liter, 415-horsepower V8 and a matching seven-speed automatic transmission from an E92-generation BMW M3 and began figuring out how to make it fit into a city-friendly hatchback delivered new with a 172-horsepower, 1.6-liter four-cylinder engine. Installing the new drivetrain directly behind the front seats would have likely been the easiest solution from a packaging standpoint, but the team decided to keep the front-engined layout. The conversion consequently required chopping out significant chunks of the Hardtop's firewall and floor, so EDM Racing started by designing and welding in a roll cage to maintain the car's structural integrity. The firm then installed modified front and rear subframes from a Subaru Impreza to keep the four wheels in their original position, or as close to it as possible. Power stressed he wants Vini to look nearly stock, especially when it comes to its track width, meaning punching out the wheel arches Renault 5 Turbo-style was out of the question.  The V8 fits surprisingly well in the Mini's engine bay, and it keeps the car's weight distribution in check. Power originally considered using a Subaru-built flat-four or a straight-six from an earlier M3, but both would have put too much weight ahead of the front wheels. Installing the automatic transmission was more difficult, however. "Making it all work in an OEM fashion will be a challenge for sure, but no more so than the most galling part of the project so far: Chopping out a transmission tunnel wide enough to accept the Getrag. I was aware of the dangers associated with cutting too much away and removing integral strength from the shell in the process, hence why we tackled the job in set stages and with the cage [installed]," EDM Racing's Elliott Dunmore explained.

Mini adding new driver assist systems to future models

With all the recent news about automated vehicle technology (from Ford, Nissan and Toyota, among others), Mini is bringing some not-so-groundbreaking tech into its products to better keep the driver connected to the car. Other than stating that these new technologies will roll out in future models, there is no telling when we could see them starting to show up, although our best guess is the 2015 Mini Cooper.
Two of the more notable technologies that Mini will introduce include a head-up display system (shown above) and the "city braking" system to work in conjunction with collision warning and passenger detection. The automated braking system is made possible with the forward-mounted camera, which is also used for adaptive cruise control, auto-dimming headlights and a street sign detection system (to relay speed limit and traffic sign info to the driver). A new parking assist feature helps drivers find a properly sized parking spot, and then drivers can take advantage of the backup camera.
Mini obviously isn't the first to introduce these technologies, but it might be among the first to bring such a large number of advanced safety features into a car priced under $30,000 - though there is no telling how much these options will cost. The automaker has issued a brief press release for its upcoming driver assist systems, which is posted below.
