Sleeper (car)
From Free net encyclopedia
A sleeper (US English) or Q-car (British English) is a car that hides high performance beneath an unassuming exterior.
Some cars come like this from the factory to suit the tastes of those who want performance without drama, whether understatedness suits their chosen image or lifestyle, or simply because they do not wish to attract the attention of the police. Many high-performance sedans, for example, look hardly different from the lower-powered models in the range; for example, the Mercedes-Benz 450SEL 6.9, Mercury Marauder, Volkswagen Passat W8, 1996 Chevrolet Impala SS, and the Ford Taurus SHO.
Owners may, in fact, reduce the evidence that their car is of high-performance by removing characteristic letterings and trimmings. Sleepers often contain stock body parts, a dull paint job, or stock or lookalike stock wheels.
Others deliberately create sleepers by hot-rodding a car's engine and drive axles and leaving the external appearance exactly the way it came from the factory. Sometimes hints of the car's true nature show if one looks and listens carefully: wider tires, a lower stance, or a different engine note.
Some simply like having performance without show, but a more predatory use of the sleeper is in street racing, where it is used to fool an opponent into under-estimating a car's performance. Some have even gone so far as to leave their cars' exteriors banged up and rusting, and sometimes even causing additional rusting with the use of battery acid. Often sleepers will be cheaper on insurance than an equally fast sports car.
Some sleeper models
Provided is a list of some "sleepers" as well as some notes about them. Most cars on this list either have a dual overhead cam V8 engine, or some form of forced induction (supercharging or turbocharging), plus there are a few that deserve honorable mention for being so common or looked over.
General Motors decided it wanted to pack a lot of punch into everyday sedans. Thus the Series I, Series II, and Series III 3800 supercharged engine was born. This engine has a good size aftermarket and provides cost-effective horsepower increases compared with most naturally aspirated engines. The Series II and Series III are the primary choices for many reasons, but especially because of the stronger internals and extra horsepower from the factory.
Below is a list of cars that carry the Series II and Series III 3800 supercharged engines. When identifying them, the plastic engine cover visible after opening the hood will clearly read "supercharged" near "Series II 3800".

Starting in 1987, Toyota begin producing what they called the Celica All-trac. It featured a turbocharged 3S-GTE DOHC 185hp I-4 and a new AWD system. Although a handful of All-trac Celicas were produced in the US, only a few thousand were ever imported. However, the same engine was used in the 1991-1999 Toyota MR2 turbo models, and the naturally aspirated version of the engine appeared in the Camry and a variety of other vehicles in their lineup, as well as the AWD system. The Toyota Camry came with a 3S-FE DOHC I-4 standard. The Camry All-trac was run as part of the line-up for a few years. In addition to the Camry All-trac, there were Previa minivans with All-trac AWD as well.
