What does the SC in SC400 stand for?
The SC stands for Sport Coupe.
The SC400 is a two‑door Lexus grand tourer introduced in the 1990s, with the "400" signaling the model’s 4.0-liter V8 engine. In North America, this car carried the Lexus SC badge; in Japan, the related model lineage appeared under the Toyota Soarer name. The SC designation has long signified Lexus’s two‑door, performance‑oriented coupes.
Origins of the SC designation
The SC prefix has been used by Lexus to identify a specific two‑door, sport‑oriented variant within the brand’s lineup. It is most closely associated with the first‑generation Soarer/SC models, where you could find both the SC300 and SC400.
Two‑door sport coupe heritage
In the Lexus lineup, "SC" denotes a sport‑focused two‑door coupe body style, intended to blend luxury features with performance. The SC300 and SC400 differed mainly in engine and performance specs, yet shared the sport coupe identity.
Key facts about how the SC designation appears in the lineup:
- SC stands for Sport Coupe, signaling a two‑door luxury performance model.
- The number (300 or 400) references the engine size: roughly 3.0L for the SC300 and 4.0L for the SC400.
- The SC badge originated in the Lexus lineup for North America; the related Japanese market cars were known as the Toyota Soarer.
The SC prefix in Lexus nomenclature thus signals a sport‑oriented two‑door coupe, with the powertrain tuned to deliver a balance of comfort and performance.
Engine and generation context
The SC400 used the 1UZ‑FE 4.0‑liter V8 engine and rear‑wheel drive, as part of the first‑generation SC lineup. The SC300, which accompanied it, used a 2JZ‑GE 3.0‑liter inline‑six. The “SC” family positioned Lexus in the luxury sport‑coupe segment during the 1990s, alongside other brands offering two‑door grand tourers.
Summary
SC stands for Sport Coupe. The SC400 specifically represents a 4.0‑liter V8‑powered variant of Lexus’s first‑generation two‑door luxury sport coupe, with the broader SC line generally signaling a sportier two‑door coupe and the number hinting at engine size.
What engine is in a Lexus SC 400?
4.0 L V8 1UZ-FE
The SC 400's 4.0 L V8 1UZ-FE, the same engine as used in the LS 400, was reported to have cost over US$400,000,000 in research and development. The engine sits behind the front axles, which makes it a front mid engine rear wheel drive vehicle. The SC 400 was honored as the Motor Trend Import Car of the Year for 1992.
Which Lexus SC has the 2JZ?
The Lexus SC 300 is the Lexus SC model that came with the 2JZ engine, specifically the naturally aspirated 2JZ-GE, which was a 3.0-liter inline-six. It was factory-equipped with this engine, while the SC 400 model came with a V8 engine.
- Model: Lexus SC 300
- Engine: 3.0L naturally aspirated 2JZ-GE
- Note: The twin-turbocharged 2JZ-GTE engine was never offered in the Lexus SC from the factory, but it was used in the Toyota Supra.
Why did Lexus discontinue the SC?
Lexus discontinued the SC primarily due to declining sales and a lack of updates, particularly with the SC 430, which was seen as outdated compared to its competitors. The model's reputation as a luxury cruiser rather than a true sports car also contributed to its poor reception and subsequent discontinuation in 2010.
Key reasons for discontinuation
- Declining sales: Sales of the SC 430 had been steadily decreasing for years. After a peak in 2002, sales dropped significantly, with the final year of production seeing only around 1,000 units sold.
- Outdated design and platform: The SC 430 was largely unchanged for its entire production run, making it feel outdated as automotive technology and design evolved. While it was updated with a new transmission and suspension in 2006, this wasn't enough to revive its appeal.
- Poor market positioning: Despite its luxury features and comfortable ride, the SC 430 was often criticized for being a "luxury convertible" rather than a true sports car, leading to poor performance comparisons with competitors like the Porsche 911 and Mercedes SL500.
- Lack of a compelling update: Lexus's initial plans for a new-generation SC were canceled, further cementing the fate of the existing model. The brand also had a new focus on its "L-finesse" design philosophy, which the SC 430 did not fit into, and was instead shifting its attention to other new models like the LFA supercar and the CT 200h hatchback.
