What engine is in a 2008 Honda Accord V6?

The 2008 Honda Accord V6 uses Honda’s 3.5‑liter J35Z-series SOHC i‑VTEC V6 engine, rated around 268 hp and 248 lb‑ft. In most sedans and automatic coupes it’s the J35Z2 with Variable Cylinder Management (VCM); the V6 coupe with the 6‑speed manual uses the J35Z3 without VCM. This engine marked a major step up for the eighth-generation Accord in power and efficiency compared with its predecessor.

Engine overview

Honda’s J35Z-series 3.5‑liter V6 in the 2008 Accord is an aluminum-alloy, 24‑valve, single overhead cam design with i‑VTEC for variable valve timing. Many trims also feature Variable Cylinder Management, which can deactivate cylinders under light loads to improve fuel economy. Output for U.S. models was widely quoted at 268 horsepower at 6,200 rpm and approximately 248 lb‑ft of torque at 5,000 rpm on regular unleaded fuel.

Engine variants used in the 2008 Accord

Below is a breakdown of which specific J35Z variant the 2008 Accord uses by body style and transmission. This helps identify whether your car has cylinder deactivation (VCM) and which calibration it likely carries.

• J35Z2 (3.5L SOHC i‑VTEC V6 with VCM): Used in most Accord EX/EX‑L V6 sedans (5‑speed automatic) and in most Accord V6 coupes equipped with the automatic transmission. Features cylinder deactivation for improved fuel economy.
• J35Z3 (3.5L SOHC i‑VTEC V6 without VCM): Used in the Accord Coupe EX‑L V6 with the 6‑speed manual transmission. Tuned without cylinder deactivation for a more consistent power delivery.

In short, if your 2008 Accord V6 is a sedan or an automatic coupe, it almost certainly has the J35Z2 with VCM; if it’s the manual-transmission V6 coupe, it has the J35Z3 without VCM.

How to confirm your exact engine variant

Where to look

If you want to verify whether your car has the J35Z2 (VCM) or J35Z3 (non‑VCM), use the following practical checks.

• Under-hood emissions label: The vacuum/emissions label typically lists the engine family; on VCM-equipped cars it will reference VCM.
• Owner’s manual and window sticker: Original documentation often calls out “Variable Cylinder Management” on applicable trims.
• Transmission and body style: A 2008 V6 coupe with a 6‑speed manual is the J35Z3; most sedans and automatic coupes are J35Z2.
• Dealer lookup: A Honda dealer can confirm the engine variant via your VIN and build data.

These steps provide a reliable way to pinpoint the exact engine configuration in your specific 2008 Accord V6 without disassembly.

Bottom line

The 2008 Honda Accord V6 is powered by Honda’s 3.5‑liter J35Z-series SOHC i‑VTEC V6. Most models use the J35Z2 with Variable Cylinder Management, while the V6 coupe with the 6‑speed manual uses the J35Z3 without VCM, with both versions rated around 268 hp and 248 lb‑ft.

Summary

Answer: 2008 Accord V6 models use the 3.5‑liter J35Z-series SOHC i‑VTEC V6—primarily the J35Z2 with VCM; the V6 coupe with the 6‑speed manual uses the J35Z3 without VCM—producing roughly 268 hp and 248 lb‑ft. This engine combines Honda’s i‑VTEC technology with strong, refined performance for the eighth‑generation Accord.
