How fast can a V6 Impala go?
The quick answer: in stock form, V6-powered Impalas typically reach top speeds around 125 to 155 mph depending on the engine and generation, with 0–60 mph times roughly 6.5 to 9 seconds. The exact figure varies by year, trim and whether the car is governed.
From its first generations to the modern era, the Impala has bridged comfortable highway cruising with progressively stronger V6 powertrains. This article surveys the main V6 configurations used in the Impala, explains how top speeds are affected by design choices, and notes practical considerations for everyday driving.
A historical baseline: 3.8L V6 era (roughly 1995–2005)
Before listing typical figures, note that early-2000s Impalas used the 3.8-liter "3800" V6. These models prioritized reliability and smoothness over outright speed; speeds and times reflect that intent.
- Engine: 3.8L V6 (3800 Series II)
- Power: typically around 180–205 hp depending on year and tune
- Estimated top speed: about 125 mph (electronically limited in many models)
- 0–60 mph: roughly 8.0–9.0 seconds
Across this era, Impalas offered comfortable highway performance with adequate passing power, but they were not built for sporty acceleration or high-speed cornering.
Modern performance: 3.6L V6 era (roughly 2014–2020)
In the mid-2010s, GM redesigned the Impala with a 3.6-liter V6 that produced substantially more power and faster acceleration, reflecting a broader shift toward more performance-oriented full-size sedans.
- Engine: 3.6L V6 (LFX/LGX family)
- Power: about 305–312 hp; torque around 264–266 lb-ft
- 0–60 mph: approximately 6.6–7.0 seconds
- Top speed (governed): commonly around 155 mph
That generation offered a meaningful jump in straight-line pace and overall refinement, while maintaining the Impala’s roomy interior and ride comfort.
Important considerations for speed numbers
Actual performance depends on multiple variables, including drivetrain (front-wheel drive vs. all-wheel drive), transmission, tire size and condition, vehicle weight from trim and options, environmental conditions, and whether the car is in a performance-oriented mode. Factory top speed figures are often governed and measured under controlled conditions, not typical street driving.
For enthusiasts curious about pushing a V6 Impala to higher speeds, planning should emphasize safety, legality, braking, and tire health. Any modifications should be approached with caution and ideally conducted with professional guidance.
Summary
Across its V6 lineup, the Impala’s top speed has ranged from roughly 125 mph in the earlier 3.8L era to around 150–155 mph in later 3.6L-equipped models, with 0–60 mph times improving from about 8–9 seconds to roughly 6.5–7 seconds. The Impala line was discontinued in the United States after the 2020 model year, so no newer stock V6 Impalas are on sale. For those curious about performance, the modern V6 Impala offers solid acceleration and comfortable highway speed, while still prioritizing cargo space and ride quality.

What is the top speed of the Chevy Impala?
It provided the last Impala SS a top speed of 154 mph, a highlight of an otherwise dull performance car.
How much horsepower does a V6 Impala have?
305-horsepower
Acceleration and Power. Under the hood of every 2020 Impala is a 305-horsepower 3.6-liter V6 engine.
How fast is the 2017 Chevy Impala V6?
Kudos to General Motors for letting the Impala stretch its legs and top out at a drag-limited 132 mph for the four-cylinder and 149 mph for the V-6.
