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.

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 bore and 100.8 mm stroke, and rated at 450 hp and 350 lb.ft 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 for the Saleen 1. The car has claimed acceleration times of 3.5 seconds for 0-60 mph 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.

Saleen Cup
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. The Saleen Cup series consists of eight races at four tracks around the United States, listed below:

The 2020 Saleen Cup was cancelled the weekend before its scheduled opening event.

GT4
Saleen plans to further modify the Saleen 1 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.
