# Saleen S1

The Saleen 1, also called the Saleen S1, is a two-seater sports car developed and built by American automobile manufacturer Saleen Automotive. It was unveiled at the 2017 LA Auto Show, and is the first car developed entirely by Saleen since the Saleen S7 ended production in 2009. Production of the Saleen 1 is planned to be 1,500 units yearly, with a starting price of US$100,000 each.

## Specifications
### Powertrain

The Saleen 1 is powered by a proprietary 2.5 litre turbocharged inline-four engine developed by Saleen (based on the GM LKW Ecotec3 engine, it has a cast aluminum cylinder block with cast-in iron liners and uses a forged steel crankshaft), with an 88.0 mm (3.46 in) bore and 100.8 mm (3.97 in) stroke, and rated at 450 hp (336 kW) and 350 lb⋅ft (475 N⋅m) of torque. The engine is mid-rear, transversely mounted and drives the rear wheels.

### Transmission

The Saleen 1 is equipped with a 6-speed manual transmission as standard, however a paddle shift automatic transmission is expected to be offered as an option.

### Suspension

The Saleen 1 uses double wishbone suspension on the front and rear axles of the vehicle, allowing for easier tuning of suspension kinematics and properties such as camber angle or toe.

### Wheels

The car is equipped with alloy wheels with diameters of 20 inches at the front and rear. The Continental tires have codes of 255/30 ZR 20 for the front and 335/25 ZR 20 for the rear. The brake calipers and rotors measure 15 inches in diameter at the front and the rear.

### Interior features

The interior of the Saleen 1 is finished mostly in leather, suede, and Alcantara. Other amenities include Sirius radio, Apple CarPlay, and a six-speaker sound system.

## Performance

The manufacturer claims a top speed of 180 mph (290 km/h) for the Saleen 1. The car has claimed acceleration times of 3.5 seconds for 0–60 mph (0–97 km/h) and 11.3 seconds for the quarter mile. These acceleration times are achieved through a power-to-weight ratio of 0.17 hp/lb (0.28 kW/kg). The Saleen 1 is also capable of 1.2g of lateral acceleration in a turn.

## Racing

The Saleen Cup was launched in partnership with SRO Motorsports Group in 2019 to demonstrate the capabilities of the S1. A modified version of the Saleen 1, called the Saleen Cup car, is the exclusive car raced in the series. The Cup car features race-spec aerodynamics, FIA standard safety equipment, and slick racing tires.
