How much horsepower does a Mark 2 have?
The Jaguar Mark II’s power level varies by engine; depending on the spec, it ranges roughly from about 120 horsepower with the 2.4‑liter engine to around 210–220 horsepower with the 3.4‑liter, and about 220–240 horsepower with the 3.8‑liter option. Exact figures depend on the year, carburetion, and condition.
Engine options and horsepower
Different Mark II variants used three main straight-six engines. The following figures reflect typical factory outputs for each engine family.
- 2.4 L – approximately 120 hp (around 112 hp net, depending on measurement standard).
- 3.4 L – approximately 210–220 hp (factory figures vary by tune and carburation).
- 3.8 L – approximately 220–240 hp, with some versions pushing higher in strong setups.
Note: The Mark II's horsepower numbers differ between gross and net ratings from the era, and modern restorations may use different fixtures or measurements. Engine wear and tuning also affect real-world output.
Historical context and variants
Produced from 1959 to 1967, the Mark II offered a balance of luxury and performance. The 3.8-litre variant was the most powerful factory option, often paired with improved gearing and suspension to maximize its performance on the road; the 2.4-litre model prioritized economy and smoothness, while the 3.4-litre split the difference.
Summary
In short, a Jaguar Mark II's horsepower depends on engine choice: about 120 hp with the 2.4 L, around 210–220 hp with the 3.4 L, and roughly 220–240 hp with the 3.8 L. For precise numbers, consult the original factory specifications for the model year in question or a restoration's documented engine configuration.
