For enhanced safety, the front seat shoulder belts of the Porsche Panamera are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Jaguar XE SV Project 8 doesn’t offer height-adjustable seat belts.
The Panamera offers available whiplash protection, which use a specially designed headrest to protect the driver and front passenger from whiplash.

The Panamera offers optional Porsche Active Safe, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The XE SV Project 8 doesn't offer collision warning or crash mitigation brakes.
A passive infrared night vision system optional on the Panamera helps the driver to more easily detect people, animals or other objects in front of the vehicle at night.

The XE SV Project 8 doesn’t offer a night vision system.
The Panamera’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The XE SV Project 8 doesn’t offer a lane departure warning system.

The Panamera 4 E-Hybrid can drive on battery power alone for up to 31 miles. The XE SV Project 8 must run its internal combustion engine to move.
An engine control system that can shut down half of the engine’s cylinders helps improve the Panamera Turbo’s fuel efficiency. The XE SV Project 8 doesn’t offer a system that can shut down part of the engine.
Regenerative brakes improve the Panamera’s fuel efficiency by converting inertia back into energy instead of wasting it. The XE SV Project 8 doesn’t offer a regenerative braking system.
The Panamera E Hybrid’s standard fuel tank has 4.5 gallons more fuel capacity than the XE SV Project 8 (21.1 vs. 16.6 gallons), for longer range between fill-ups. The Panamera’s standard fuel tank has 7.1 gallons more fuel capacity than the XE SV Project 8 (23.7 vs. 16.6 gallons).
The Panamera offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The XE SV Project 8 doesn’t offer an SMG or a conventional manual transmission.

XE SV Project 8
For better traction, the Panamera’s optional tires are larger than the largest tires available on the XE SV Project 8 (F:275/40R20 & R:315/35R20 vs. F:265/35R20 & R:305/30R20).
For better ride, handling and brake cooling the Panamera offers optional 21-inch wheels. The XE SV Project 8’s largest wheels are only 20-inches.
The Panamera offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The XE SV Project 8 doesn’t offer an active sway bar system.
The Panamera offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Jaguar doesn’t offer an active suspension on the XE SV Project 8.
The Panamera has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Panamera’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The XE SV Project 8 doesn’t offer a load leveling suspension.
For a smoother ride and more stable handling, the Panamera’s wheelbase is 4.5 inches longer than on the XE SV Project 8 (116.1 inches vs. 111.6 inches). The Panamera Executive’s wheelbase is 10.4 inches longer than on the XE SV Project 8 (122 inches vs. 111.6 inches).

Unlike the driver-only memory system in the XE SV Project 8 Premium/Prestige/Portfolio/R-Sport/S, the Panamera offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.
The Panamera’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The XE SV Project 8 does not have an oil pressure gauge.
To improve rear visibility by keeping the rear window clear, the Panamera offers an optional rear wiper. The XE SV Project 8 doesn’t offer a rear wiper.
