Singer Vehicle Design’s meticulous and uncompromising approach to restoring classical Porsche cars has earned it a cult following and project costs stretching far into six-digit territory. This example is none other than the famous Brooklyn Commission, and it could be yours for over £500,000.

The car is Singer’s eighth project, and it was finished in 2012. A Porsche 911 (964) with a clean record was picked as the donor, landing with plentiful structural reinforcements and carbon-fiber bodywork. Öhlins suspension was installed for better handling, and a roll cage was put inside the cabin.

An elegant green exterior contrasts nicely with an all-purple interior wrapped floor to ceiling in Alcantara. The same trim is found on the engine deck lid, under which a Cosworth 3.8 flat-six toils producing 375 PS (370 hp / 276 kW). As befits a classic Porsche restomod, a six-speed transmission drives the rear wheels.

Boosting a BMW 2 Series Coupe to 572 mechanical horsepower is a challenging, but not impossible task. Fitting it with a nitrous-oxide injection system is also possible if racecar-like acceleration is required. But performing all of the above on a DIESEL car? If it weren’t for this video by cars.co.za, we’d think it impossible.

Pictured here is a 220d spec rocking one of the most powerful diesel engines ever made in Bavaria. The massive six-banger uses its triple turbos to slam the transmission with 381 PS (376 hp / 280 kW) and 740 Nm (546 lb-ft) straight from the factory. How can you even begin to modify a monster like this?

Apparently, you can. The tuner adds a custom cooling system, methanol injection, the NOS mentioned above and a plethora of other components. In the end, the ride churns out 580 PS (572 hp / 427 kW) along with more than 1,000 Nm (738 lb-ft) of torque.

Other notable modifications include M2-style fenders and bumpers, a rather pronounced hood, a carbon trunk lid with a spoiler on it, and a cabin with two M3 seats and a roll cage pained red. Watch the video for a closer look at this remarkable one-off.

A tastefully tuned Porsche 911 Turbo convertible found a new owner in the USA, who parted with a considerable sum to obtain a 996-gen vehicle with Need For Speed: Porsche Unleashed styling.

The video game came out as far back as 2000 (felling old yet?), and the car received its tuning treatment in 2004. It ended up with an all-new chassis, admittedly rather controversial mirror headlights, nice curved bodywork, a massive front apron, and a custom rear spoiler. 19-inch MHT wheels with black spokes and polished rims filled out the arches.

Elsewhere, the one-off sports car received red brake calipers, coilover-based suspension, and aftermarket stainless-steel exhaust tips. The cabin comes trimmed with leather, seats are power-adjusted and heated, and climate control is provided for when the weather gets nasty.

Despite its solid age, the 911 Turbo went for U.S. $47,000. If you are feeling nostalgic about the game right now, you may refresh your memories by watching the embedded video.

All owners of the 2021 BMW M4 coupe may now choose from a wide range of exterior and interior accessories custom-tailored for it by AC Schnitzer.

The controversial front end of the German sports car gains an original splitter and side canards made of carbon fiber, which the tuner claims gives it improved aerodynamic performance in addition to just an extra pinch of visual aggression.

The list goes on to mention carbon side skirts, a neat spoiler lip at the rear and a rather prominent diffuser. As for the wheels, you could go for any of the available 20-inch forged designs on the list, preferably while also dropping the ride height by about 20 mm (0.8 inches) on both axles for maximum effect.

The interior modifications are all the usual fare: floor mats, pedal pads, paddle shifters – you know the drill. A power upgrade is in the works that should raise the output from 480 to 510 metric horsepower through the installation of a sports-grade exhaust system. The availability and pricing remain unknown, unfortunately.

Ever since Lamborghini unveiled its ultra-fast, ultra-expensive SUV named Urus, people on salaries all over the world have been frantically searching for reasons not to buy it. If the above sounds familiar, here’s another compelling reason, brought to you by ABT Sportsline.

The tuner worked its magic on the SQ8 model not long ago (watch the video for an overview), and is now bringing a similar range of improvements to the SQ7 as well. The main course is an aftermarket ECU that boosts the stock eight-cylinder to 650 PS (641 hp / 478 kW) and 850 Nm (627 lb-ft) of torque. The Italian super-SUV gets the exact same figures from the same engine model.

ABT never bothered to measure sprint times for the SQ7, but the SQ8 can hit 100 km/h (62 mph) in 3.8 seconds and only reaches the limit at 270 km/h (168 mph).

Other notable upgrades include a rather restrained body kit, enlarged exhaust tips, 22-inch in-house wheels wrapped in Continental rubber, and an all-black body finish with the only red accents being the calipers and the grille badge.

Buying your very own ABT SQ7 in Germany is a matter of having €121,000+, while the stock car starts from €92,200.

BMW must have felt that its X7 SUV was powerful enough not to develop an M version of it, but some owners beg to differ and go to tuner shops for a solution.

Swiss tuning house dÄhler Competition offers a nice alternative to the non-existent X7 M, boosting it by 110 horsepower and improving suspension, exhaust and wheels.

Once all is said and done, the SUV hits the wheels with 630 PS (621 hp / 463 kW) and 830 Nm (612 lb-ft) of torque. The company mentions that a Stage 2 kit is in development, but the figures don’t seem that impressive: the power gain will apparently amount to 16 PS (16 hp / 12 kW) and the torque to 20 Nm (15 lb-ft).

The new exhaust system offers a valve for precise sound control, and you can adjust it on the go using buttons on the steering wheel. Stock air-ride suspension benefits from a lowering module that brings it several millimeters closer to the ground. Rounding off the exterior mods are 23x11-inch forged wheels with a ten-spoke pattern.

Swing open a door to find a new odometer marked all the way up to 330 km/h (205 miles per hour), aluminum pedal pads, and the mandatory branded floor mats.

Brabus counts among the most successful and prolific tuners when it comes to customizing Mercedes-Benz cars. After revealing the “Brabus 800” take on the Mercedes-AMG E63 S, the company has now complemented the range with two other conversions based on the AMG GLE 63s and the AMG GLS 63. For now, let us focus on the latter.

The three-row SUV has all the signature Brabus traits, including a rather aggressive carbon body kit consisting of a front spoiler, a rear diffuser, exhaust finishers, front bumper air intakes, and grille intakes. A stylized letter B replaces the tri-pointed star badge, and the grille boasts red stripes for contrast.

Complementing the new image are a 25mm (1”) suspension lowering, 24-inch forged wheels, an active-valve performance exhaust system, and an opulent cabin makeover.

Last but by no means least, a PowerXtra B40S-800 kit targets the stock four-liter twin-turbo V8 to raise its output to 800 PS (789 hp / 588 kW) and 1,000 Nm (738 lb-ft) at the crank. Bolstered like this, the bulky off-roader runs the standard sprint in mere 3.8 seconds.

The new Mercedes-AMG G63 enjoys a rather unique market standing, being equally popular among luxury car connoisseurs, off-roading enthusiasts, and tuning aficionados. With its latest project, Hofele may as well have been targeting all three groups at once.

Even compared to the earlier HG 63 projects, the Limitless stands out as one of the most opulent and painstakingly detailed. Its exterior is finished in Citrine Brown Magno, a hue that highlights the muscular and boxy body of the G-Class perfectly. Giant 24-inch forged wheels topped by carbon fender flares complement the image nicely, as do carbon mirror housings and fully automatic side steps now spanning the entire length of the sides.

Peek inside, and you will be overwhelmed with orange-tinted Nappa leather and matching Alcantara. Rare inclusions of black and carbon details just about manage to rescue the viewer from sinking into this veritable sea of tangerine.

Hofele said nothing about the power or the pricing, but it did mention a while ago that custom jobs like this one started from €300,000 plus taxes.

You know, it just happens sometimes that someone buys a shiny new Mercedes-AMG E 63 S 4Matic+ only to discover that 612 PS (603 HP / 450 kW) somehow doesn’t feel crazy enough. Some seek professional medical help; others turn to Brabus for an upgrade.

The Brabus 800 you see here benefits from dual high-performance turbochargers rated at 1.6 Bar max, an ECU remap, and carbon-fiber air intakes built into the radiator grille sides. The net result is a power boost of 188 PS (185 hp / 138 kW) and a torque boost of 150 Nm (110 lb-ft), to a total of 800 PS (789 hp / 588 kW) and 1,000 Nm (738 lb-ft).

There is also no avoiding mentioning the high-flow, quad-tip, stainless-steel exhaust system. Brabus says you can easily fine-tune the sound profile using built-in valves, up to the point when you can be obnoxiously loud at 30 km/h (18 mph), but nearly silent when neighbors come after you.

Polish car customizer Carlex Design has finished working on another major project, this time around coming up with a truly unique interior for the 800-HP Ferrari 812 Superfast.

The cockpit greets with an abundance of black leather and matching Alcantara, while the seats and the dashboard sport fashionable grey inserts. Elegant stitching and perforation adorns the entire trim even up to the ceiling, where no such detailing is usually found. Plentiful carbon fiber details round things off along with new floor mats and a plaque behind the seats testifying to the uniqueness of this car.

The exterior and the engine stay stock, if you can call a 6.5-liter naturally aspirated V12 “stock”. The wheels get hit with around 800 PS (789 hp / 588 kW) and 718 Nm (530 lb-ft) of torque, taking the coupe from zero to 100 km/h (62 mph) in 2.9 seconds. Top speed lies at 340 km/h (211 mph).
