Jaguar XF 5.0 Mk I vs Jaguar XJ 3.0 340

Over a standing quarter mile on dry asphalt the Jaguar XF 5.0 Mk I is the quicker car, covering it in 13.40 s at 105.8 mph against the Jaguar XJ 3.0 340’s 14.26 s — a margin of 0.86 s. To 60 mph the Jaguar XF 5.0 Mk I takes 4.96 s and the Jaguar XJ 3.0 340 5.78 s.

Simulated, not measured — computed from each car’s published kerb mass, rated power and drivetrain, then fitted to its own published acceleration figures. Dry asphalt, 20 °C, sea level, 1 ft rollout.

Questions

Is the Jaguar XF 5.0 Mk I or the Jaguar XJ 3.0 340 faster?
The Jaguar XF 5.0 Mk I. Over a standing quarter mile it runs 13.40 s to the Jaguar XJ 3.0 340's 14.26 s, a margin of 0.86 s, and it reaches 60 mph in 4.96 s against 5.78 s. These are theoretical times from a physics simulation, not measured runs.
What is the Jaguar XF 5.0 Mk I 0-60 time?
The Jaguar XF 5.0 Mk I reaches 60 mph in 4.96 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 13.40 s at 105.8 mph.
What is the Jaguar XJ 3.0 340 0-60 time?
The Jaguar XJ 3.0 340 reaches 60 mph in 5.78 s, simulated on dry asphalt at 20 °C with a 1 ft rollout. It covers the standing quarter mile in 14.26 s at 100.2 mph.
What trap speed does each car run?
The Jaguar XF 5.0 Mk I trips the lights at 105.8 mph and the Jaguar XJ 3.0 340 at 100.2 mph at the end of the quarter mile. These are theoretical times from a physics simulation, not measured runs.
Are these real measured times?
No. Every time on this page is produced by a physics simulation, not by a stopwatch at a drag strip. Each car is modelled from its published kerb mass, rated power, drivetrain and gearing, then trimmed until it matches its own published acceleration figures — 9 of 10 for the Jaguar XF 5.0 Mk I and 2 of 2 for the Jaguar XJ 3.0 340. Conditions are identical for both cars: dry asphalt, 20 °C, sea level, 1 ft rollout.
