AMG GT63 RIIIx based on the Mercedes-AMG GT63 S 4-Door Coupé

The American company Renntech is known for performance modifications of Mercedes-AMG cars, and this time it presented a limited edition AMG GT63 RIIIx based on one of the most powerful cars of the Stuttgart-based company, the Mercedes-AMG GT63 S 4-Door Coupé.

The car is powered by a 4.0L V8 engine with more than 1,196 hp (880 kW) and 927 lb-ft (1,257 Nm) of torque. This significant increase in power compared to the most powerful GT63 S 4-Door Coupé (843 hp /620 kW) is achieved thanks to new turbochargers, a new air intake system, a remapped ECU and a better adaptive exhaust system. That’s enough power to push the car to 62 mph (100 km/h) in 2.6 seconds, while the top speed is unknown.

The RIIIx Performance Package brings Stainless Steel Downpipes, 200 Cell Sport Catalytic Converters downpipes, BMC air filters designed to last longer and create more power than the OEM paper filters, Stainless Steel Sport Mufflers, an upgraded intercooler, and upgraded brakes. It’s mounted on 21 and 22-inch reinforced Renntech RPS 10.2 alloy wheels wrapped in Michelin Pilot Sport 4S tires.

When it comes to price, the RIIIx Performance Package costs 89,000 euros.

Renner Projekt 8 based on the BMW 8 Series (E31)

The American company Renner Projekts specializes in modifying German sportscars of the 1980s and 90s. Their latest work is an extraordinary car called Renner Projekt 8 based on the BMW 8 Series (E31).

The standard BMW 8 Series (E31) is powered by a 5.0L V12 engine, but after the intervention of Renner’s engineers, the car is now powered by a 4.9L V8 engine with 485 hp (357) from the 2002 BMW M5. Three additional powerplant options are also offered: E39 M5 S62 / V8 / 400 hp, E92 M3 S65 / V8 / 418 hp and E60 M5 / V10 / 500 hp. Engine power is transmitted to the rear wheels via a 6-speed manual gearbox.

The engineers reassembled the entire engine, installed ARP bearings, new camshaft pulleys, and improved air flow on the intake and exhaust sections of the compression chamber. Also, discs and brake calipers were taken from the E60 M5 (front) and E39 M5 (rear) models.

The interior has been re-upholstered in yellow leather. A new two-zone air conditioner, a ZHP gear lever was installed, while the ceiling was made of Alcantara. The “Projekt 8” plaque located between the front seats emphasizes the importance of the car.

It is interesting that the car was for sale, but despite the offered price of 227,000 dollars, it was not sold because it did not reach the reserved price.

Cadillac Escalade upgraded by Mansory

Mansory is well known for upgrading the world’s major automotive brands such as Porsche, BMW, Mercedes, etc., and now it has embarked on an adventure for the first time with the fifth-generation Cadillac Escalade, which premiered in 2020.

The car received several carbon body components, but what catches the eye at first sight are the impressive 26-inch black rims wrapped in 295/30 tires, which makes the 5.38-meter-long car look even bigger. As a reminder, the standard Escalade comes with 22-inch wheels wrapped in 275/50R22SL front and 275/50R22SL rear tires.

Cadillac Escalade is powered by a 6.2-liter V8 engine with 420 hp (309 kW) and 460 lb-ft (623 Nm) of torque. Power is sent to the rear wheels via a 10-speed automatic transmission. However, thanks to the tuning, the car now has 455 hp (335 kW) and 479 lb-ft (650 Nm) of torque.

Also, Mansory has announced an upgrade of the Cadillac Escalade V-Series. It is powered by a 6.2-liter V8 engine with 682 hp (502 kW) and 653 lb-ft (885 Nm) of torque, so the engine power can be expected to exceed 700 hp (515 kW). More details will be known soon.
