Saleen S7 Twin Turbo

Saleen S7 Twin Turbo 2005

Saleen knows all about power. As in S281 Mustangs, N2O Focuses and the S7, America's first (and still the only) mid-engine exotic supercar. When it went on sale in 2002, the S7 was the only street-legal car in the U.S. with more than 500 horsepower and 500 lb-ft of torque. The media and S7 owners have raved about the car since it first smoked the rear tires in anger. And it has been recognized by numerous automotive magazines as the fastest production car in the world.
But during the past three years the automobile marketplace has witnessed an explosion of performance with models from manufacturers including Ferrari, Lamborghini, Mercedes-Benz, Porsche and Chevrolet touting power numbers above the once magic 500 level.

What's New for 2005
It was pretty obvious to Saleen product planners during the late 1990s that horsepower and torque numbers were trending upwards, especially among the purveyors of supercars. And power figures that looked spectacular at that time might seem quite ordinary a few years down the road. So Saleen engineers have been planning for this day since they drew the first line on a computer screen for the original S7's 7-liter engine.

Engine & Drivetrain
Designed by Saleen engineers, the S7's engine and drivetrain incorporate the latest in modern racing technology. The new all-aluminum V8 engine casting was engineered and tooled by Saleen to displace seven liters. Redline is 6500 rpm. Space age materials and engineering are used throughout, including stainless steel valves, titanium retainers, beryllium exhaust valve seats, an aluminum throttle body, Saleendesigned aluminum CNC-machined cylinder heads and stainless steel exhaust system.
An exclusive Saleen-designed Front Engine Accessory Drive (FEAD) system results in an extremely compact engine, allowing for better packaging and overall weight distribution. The V8 incorporates a unique Saleen-designed side-mounted water pump, a belt-driven camshaft drive and a Saleen-engineered dry sump oil delivery system.
The engine's mid-chassis placement optimizes weight distribution and center of gravity, making room for an unusually tall engine that allows for a very efficient induction system. Air enters a roof intake, passes through a 90-mm mass air meter and feeds into a carbon fiber plenum. From the plenum the air is routed to the twin ball bearing turbos, is pressurized to 5.5 psi max and then passes through an oval-bore throttle body into an aluminum intake manifold with eight individual runners.

The four exhaust pipes from each bank of cylinders merge into a race-car-like high-efficiency collector. In addition, the exhaust incorporates dual catalysts per cylinder bank, EGR and those aforementioned twin wastegates. And because Saleen believes in power and clean air, the emission control system features dual, heated oxygen sensors per cylinder bank and a high-volume evaporative emission system along with those four catalysts. Oh, and for good measure and clean air, the system is OBD-II compliant.

Chassis, Suspension & Brakes
The S7 chassis and suspension incorporate decades of Saleen's experience in racing, racecar construction and high-performance road car manufacturing. The Saleen S7 architecture begins with a space frame chassis to which honeycomb composite reinforcing is grafted. The body is structural, aerospace-quality, autoclave carbon fiber.
Suspension is via fully independent unequal-length double wishbones with coilover springs, lightweight aluminum dampers (shock absorbers) and stabilizer (anti-roll) bars front and rear. The uprights at each corner are CNC machined billet aluminum, flow-through designs that use air to help cool the bearings.

Chassis tuning also includes revised shock valving front and rear. Saleen-engineered Brembo-supplied lightweight aluminum six-piston mono-block calipers are fitted front and rear.
The brakes are among the largest of any production car with 15-inch vented discs up front and 14-inch vented discs at the rear.
The Saleen-designed forged alloy wheels feature center locking wheel nuts with automatic safety locks. Sizes are 19 x 9.5 inches up front and 20 x 12 inches at the rear.

Body Design
The S7's beautiful shape was "designed" by the wind. Optimal aerodynamics and top speed performance objectives were achieved with extensive wind tunnel work. Targets included a low coefficient of drag, optimum drag-to-lift ratio, and extreme down force. The S7 has "full tray" body sculpting underneath.
Longtime Saleen design consultant, Phil Frank, and Steve Saleen then personalized and refined the aesthetics of the S7 to reflect modern supercar thinking. The gill-like ducting is, of course, fully functional. The autoclaved carbon fiber body panels incorporate advanced aerodynamics and include integrated split-channel airflow throughout the car, full underside air management, and advanced front tray and side skirt designs and an integrated full-body rear spoiler, replacing the wing used previously.

Interior
A much care has been given to the creature comforts of the Saleen S7 as to its performance. Great attention was given to seating position. The car features asymmetrical seating, with the driver position moved slightly more to the center than the passenger. This improves the driver's ergonomics and the side-to-side weight distribution. Because the S7 features a custom fitted driver seating position with 6 adjustable pedals and a tilt and telescoping steering wheel, it comfortably accommodates tall drivers. While Shaquille O'Neal would have a tough time fitting behind the wheel of an S7, drivers as tall as 6 feet 6 inches can enjoy the S7 driving experience.

Seats and other interior surfaces are covered in elegant leather and suede. Air conditioning, power windows, power door locks with remote keyless opening for the doors and both trunks, an electric-headed front windshield, variable intermittent windshield wipers, a leather-wrapped steering wheel and an AM/FM/CD/DVD/TV system are all standard. The Saleen S7 also has one unique interior feature: a video "rearview mirror" - there is a small video camera inconspicuously mounted in the rear of the car.

Dual Personality
The Saleen S7 Twin Turbo was conceived to combine the performance of a track-only racecar with the driving pleasure of a road car. As a result, while the S7 would be at home on any racetrack, it is also a car that can be driven with pleasure on highways, Autobahnen and back roads.

Racing Successes
Unlike most exotic supercars, the racing version, the S7R, has already proven itself on the international motorsports stage. During the past three years, the racing version has won more than 50 poles, set fastest race lap over 50 times and has been victorious well over 40 times, winning seven GT Championships. This incredible record includes winning the prestigious 12 Hours of Sebring and setting a new track record at the famed 24 Hours of Le Mans.
The S7R has won a number of FIA GT races so that victory stands as one among many. What was more significant is that the race took place at Imola, Italy, home track of Ferrari and Maserati, and the big story that weekend was supposed to have been the heralded debut of the Maserati MC 12s. Instead, Saleen S7Rs dominated qualifying, placing 5 cars in the top 10 and added insult to injury when the Vitaphone S7R finished the race with a 43-second advantage over the second-place Maserati.

Best-in-Practice Design
While the S7 is an American supercar, the vehicle itself reflects a "best-inpractice" philosophy, where Saleen has incorporated superior components from around the globe in order to manufacture the best vehicle possible. For example, the Saleen S7 uses Saleen-engineered/ Brembo-supplied brakes from Italy as well as numerous high technology pieces from companies located in the Midlands area of the United Kingdom, a region that is to motorsports what the Silicon Valley is to computers. Initial wind tunnel testing was conducted at the University of Glasgow in Scotland.

The Manufacturer's Suggested Retail Price (MSRP) for the 2005 S7 Twin Turbo is $555,000. That's $100,000 less than an Enzo (which is out of production and escalating in price) and nearly $300,000 fewer dollars than the Maserati. And you could have Her and His S7s for the price of the McLaren F1!
When it comes to performance AND value, nothing on his planet can come close to matching the S7 Twin Turbo.
