How is a Stretch Limousine Constructed?
Building or stretching a limousine is no simple task. The process of taking a standard, mass-produced automobile such as a Lincoln Town Car or Cadillac Seville, and producing a full-sized, fully loaded limousine involves many processes. In addition to these processes, a team of well-trained professionals are required. Such professionals are welders, interior fabricators, engineers, mechanics and safety professionals.
A base vehicle, usually a Lincoln Town Car is bought from the manufacturer and then is stripped, cut and separated into two separate halves. Many mass-produced vehicles start this process, from Cadillacs, Escalades to Hummers, although, many such vehicles are not recommended to be stretched into limousines.
Once split, the vehicle has its framework extended with steel structures—this establishes the "stretch." The structures are welded into place and require very detailed precision to ensure a consistent, uniform structure of the chassis; an inconsistent "stretch" could cause both mechanical and safety concerns in the future.
The added "stretch" module typically requires custom components and is internally produced by each individual coachbuilder. Such components include fiberglass, ABS plastic, wood cabinetry, wood finishes, upholstery, interior trim, laser cut metal fabricated parts, electrical finishes and more.
Once the stretch is added, the vehicle is moved to a body finishing process. This is where all added parts and assemblies are prepped for painting. After prep, the vehicle is painted or "baked" in a paint spray room.
After painting, the vehicle is fashioned with the necessary electrical systems which include full limousine wiring. Next, the limousine is provided with detailed interior amenities: Professionals install luxury seating, mirror finishes, wood trim and other luxury amenities.
After completion, the limousine undergoes a thorough inspection process and road test which examines drivability, undercarriage, amenities, water leaks, etc. Each inspection varies by coachbuilder.
