What are the specs of the Lexus is3000?

The model name “Lexus IS3000” does not exist in Lexus’s current or historical lineup. The closest and real options are the IS 300, IS 350, and, in some markets, the IS 500. Here’s what those actual models offer, so you can navigate the specs you may be after.

Is there a Lexus IS3000?

No. Lexus has never produced an IS model with the number 3000 in its badge. The numeric suffixes used in the IS line have been IS 200/IS 250, IS 300 (in some generations and markets), IS 350, and IS 500. If you’ve seen “IS3000” referenced, it’s likely a misunderstanding or a misprint related to one of the real IS variants or a regional badge. The rest of this guide focuses on the actual current IS options and their specifications.

Current Lexus IS lineup: quick snapshot

IS 300 (current generation)

Below is a concise specs snapshot for the IS 300 as sold in recent U.S. markets. The model uses a turbocharged 2.0-liter inline-4 engine, with outputs around 241 horsepower and 258 lb-ft of torque, paired to an 8-speed automatic transmission. Rear-wheel drive is standard, with all-wheel drive available. Performance and efficiency vary by drivetrain and model year.

• Engine: 2.0-liter turbocharged inline-4


• Horsepower: 241 hp


• Torque: 258 lb-ft


• Transmission: 8-speed automatic


• Drivetrain: RWD standard; AWD available


• 0-60 mph: roughly 6.0–7.0 seconds (drivetrain/tires dependent)


• Top speed: electronically limited, generally around 140–143 mph depending on year


• Fuel economy (EPA estimates): typically in the mid-20s mpg combined, with variations by drivetrain and year

In short, the IS 300 is the turbocharged four-cylinders’ entry in the IS lineup, balancing performance with efficiency and offering AWD as an option for traction.

IS 350 (current generation)

The IS 350 sits above the IS 300 in the lineup, using a naturally aspirated V6 with more straightforward, muscular performance. It’s widely available with rear- or all-wheel drive and comes with a broader power and torque curve, along with the same 8-speed automatic transmission framework.

• Engine: 3.5-liter V6


• Horsepower: about 311 hp


• Torque: about 280 lb-ft


• Transmission: 8-speed automatic


• Drivetrain: RWD standard; AWD available


• 0-60 mph: approximately 5.6 seconds (varies by configuration)


• Top speed: electronically limited, typically around 143 mph


• Fuel economy (EPA estimates): commonly around 20–22 mpg city / 28–32 mpg highway, depending on year and drivetrain

The IS 350 emphasizes stronger straight-line performance and a more traditional V6 character, while still offering the refined interior and ride Lexus buyers expect.

IS 500 (for reference and context)

For context, the high-performance IS variant in some markets is the IS 500, which uses a 5.0-liter V8 and delivers significantly more horsepower and a sharper throttle response. It’s not a model badge that would be confused with “IS3000,” but it’s part of the IS family’s performance spectrum.

• Engine: 5.0-liter V8


• Horsepower: roughly 472 hp


• Torque: around 395 lb-ft


• Transmission: 8-speed automatic


• Drivetrain: RWD standard; AWD variants


• 0-60 mph: around 4.3 seconds


• Top speed: electronically limited around 168 mph


• Fuel economy (EPA estimates): typically lower than the IS 300/350 due to the V8

IS 500 represents the performance apex of the current IS family, offering a high-revving V8 experience within the same sedan platform.

Why the naming confusion persists

Automotive naming can be confusing across generations and markets. Lexus has used different suffixes (250, 300, 350, F Sport, etc.) to denote engine and trim differences. If you’re shopping or researching, verify the model year and market (U.S., Europe, Asia, etc.) to ensure you’re looking at the right specs for IS 300, IS 350, or IS 500.

Summary

There is no Lexus IS3000 model. The current and historical IS lineup centers on IS 300, IS 350, and IS 500, with varying engines and drivetrains. The IS 300 uses a 2.0-liter turbocharged four-cylinder (about 241 hp), the IS 350 uses a 3.5-liter V6 (about 311 hp), and the IS 500 features a 5.0-liter V8 (about 472 hp). If you meant to ask about a different model or a specific market’s variant, share the year and region and I’ll provide the precise, up-to-date specifications.
