GRS
Iconic sport classic redefined.Porsche 911 G model remastered by Tedson Motors under the code name GRS represents our sporty interpretation of Porsche’s most recognizable, original body line. While most today’s restomods refer to first generation long hood body, we wanted to pay tribute to 911’s longest lasting body line of the G model (1974 – 1989) whose chassis is superior to older generations while still pure, free of modern technologies and electronics. Through our refined study of the early turbo body and the IROC cars, we have created GRS, combining astonishing looks and fine craftsmanship with very authentic and engaging driving experience.
Tedson's GRS project represent an exclusive restomod series focused on providing 911 G model with long awaited and very deserving refresh and facelift. By incorporating the elements of popular wide body turbo and IROC cars all wrapped in Tedson's unique package, GRS exudes confidence, sportiness and exclusiveness. IROC front bumper was carefully redesigned by inclining the radiator housing to assure sleeker line and better aerodynamics while the front and rear air intakes refresh the car by giving it a more contemporary look. By adding modern lighting and atractive double exhaust tips, the car dominates the road with its powerful stance while retaining the original 911 sport classic vibe.
All the cars are fully restored by hand in a so called nut-to-bolt process and the cars are delivered to their commissioners in a new condition. Most mechanical parts are OEM and the cars can be serviced at any Porsche authorized service .
GRS is offered with standard combustion engine or with electric motor as fully electric vehicle.
GRS BODY KIT
Based on large numbers of global 911 G-model owners who take great pride in maintaining and restoring their vintage cars, Tedson Motors decided to offer complete GRS body kit for independent installation.
All body kit components are produced out of high-quality carbon fiber making them durable and light. Aside of full body kit, each component can also be purchased separately.
