BMW.SG | BMW Singapore Owners Community The Ultimate BMW Community – Established Since 2001
Originally a BMW Z4, Willem and Kaess Smit were inspired to design a hybrid version of the retro-flavoured coupe. All body panels were handcrafted from carbon fibre to match the design of the modern 507 counterparts.
It is called the Smit Oletha and has been assembled over the last few years using parts from Bavaria’s parts shop. The E86 BMW Z4 was made three times stiffer than the Z8 by the Californian duo and used the 4.0-litre engine from the E92 M3. Instead of simply installing a new engine, the 4.4-litre V8 from the M3 GTS was heavily modified.
Top Gear has released a new video featuring the stunning coupe, and it sounds amazing. The engine produces 450 hp and 340 lb-ft of torque at the rear axle. Six-speed ZF manual transmission from the E92 M3 with mechanical limited-slip differential. The engine exhales through 3D-printed exhaust tips. The sprint from 0 to 100 km/h takes four seconds in a car weighing 1,401 kilograms.
The wheels are made from a single piece of aluminium and have Michelin Pilot Sport 4 S tyres. They have an old-school design while using modern technology. Behind them are AP Racing brakes for extra thrust from the V8. For packaging reasons, the BMW Z4 uses the steering pump from an E60 M5. The restomod BMW Z4 also has an adjustable suspension and more than 100 3D-printed components.
