The Saleen S1, also called the Saleen 1, is an American two-seater sports car built by 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 2007. Production of the S1 is planned to be 1,500 units yearly, with a starting price of US$100,000 each.
The S1 is powered by a 2.5 litre turbocharged inline-four engine developed in-house by Saleen, generating a maximum of 450 hp (336 kW) and 350 lb⋅ft (475 N⋅m) of torque. The engine is mid-rear mounted and drives the rear wheels.
The S1 is equipped with a 6-speed manual transmission as standard, however a paddle shift automatic transmission is expected to be offered as an optional upgrade for the production S1.
The S1 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.
The S1 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.
The interior of the S1 is finished mostly in leather, suede, and Alcantara. Other amenities include Sirius radio, Apple CarPlay, and a six-speaker sound system.
The manufacturer claims a top speed of 180 mph (290 km/h) for the Saleen S1. 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 S1 is also capable of 1.2g of lateral acceleration in a turn.
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 S1, 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. The Saleen Cup series consists of eight races at four tracks around the United States, listed below:
Saleen plans to further modify the S1 Cup car for GT4 homologation for the 2020 season. Saleen's plan includes the introduction of a factory racing team, with at least one driver sourced from the winners of the summer 2019 Saleen Cup.
