Porsche Panamera 4S Diesel 2017 Review: 416Hp, 41Mpg

The 2017 Porsche Panamera 4S Diesel marks a pivotal moment in the evolution of high-performance luxury vehicles, blending blistering acceleration, exceptional fuel efficiency, and everyday usability into one sophisticated package. Powered by a newly developed 4.0-liter twin-turbo V8 diesel engine producing 416 horsepower and a staggering 850Nm of torque, this model accelerates from 0-62mph in just 4.2 seconds, achieving a top speed of 178mph, making it the fastest production diesel car at the time.

Engine and Powertrain Excellence

At the heart of the Panamera 4S Diesel lies an all-new 4.0-liter twin-turbocharged V8 diesel engine, engineered within the Volkswagen Group for seamless integration with Porsche’s performance ethos. This powerplant delivers 416bhp and peaks at 850Nm of torque available from as low as 1,000rpm, ensuring effortless overtaking and surging acceleration without needing high revs. Paired with an eight-speed PDK dual-clutch automatic transmission and standard all-wheel drive, power distribution is precise and responsive, propelling the 2.1-tonne saloon with sports car-like urgency.

Reviewers noted the engine’s refined character: a deep rumble on startup evolves into a purposeful V8 growl under load, far removed from typical diesel clatter. On test drives, it achieved real-world figures of 37mpg over mixed routes, closely aligning with Porsche’s official 41mpg claim, showcasing its frugal side for long-distance cruising. In high-speed runs, it comfortably exceeded 170mph, pulling strongly without strain.

• Peak Power: 416bhp @ 3,000-5,000rpm
• Peak Torque: 850Nm @ 1,000-3,250rpm
• 0-62mph: 4.2 seconds
• Top Speed: 178mph
• Fuel Economy: Up to 41mpg (combined)

Advanced Chassis and Handling Dynamics

Built on the MSB platform shared with future Bentley models, the second-generation Panamera benefits from a ground-up redesign emphasizing rigidity and balance. The 4S Diesel incorporates a three-chamber air suspension system with Porsche Active Suspension Management (PASM), delivering a compliant ride on motorways that firms up admirably in corners.

Handling is where it truly shines: rear-axle steering enhances maneuverability, reducing the turning circle for urban agility, while providing stability at high speeds. Testers praised the intuitive steering feedback, minimal body roll, and grip levels that allow it to carve through twisty roads with precision typically reserved for two-seaters. The 4D Chassis Control system dynamically adjusts damping, ride height, and torque vectoring for optimal composure. Braking is equally impressive, with large ventilated discs (optional ceramics) offering fade-free stopping power even under repeated hard use.

Interior Refinement and Technology

The cabin represents a quantum leap, featuring a driver-focused layout with dual high-definition touchscreen displays spanning 12.3 inches each for instruments and infotainment. Touch-sensitive buttons and haptic feedback streamline controls, though some functions like air vent adjustments require menu navigation. Materials are sumptuous: soft leather, piano black or carbon fiber trims, and meticulous build quality create an ambiance rivaling the best in class[10].

Space is generous for a performance saloon, with ample rear legroom and a 500-liter boot expandable to 1,300 liters. Four-zone climate control and ambient lighting enhance comfort, but base models omit heated seats and rear USB ports, which are standard on cheaper rivals—options that inflate the £91,000+ price tag. The Porsche Communication Management (PCM) system supports Apple CarPlay and navigation with vivid graphics.

Design and Practicality

Externally, the Panamera 4S Diesel adopts sleeker lines reminiscent of the 911, with a lower roofline, sculpted flanks, and adaptive LED matrix headlights. At 5 meters long, it’s imposing yet elegant, with active aerodynamics optimizing downforce and efficiency. Practicality improves over the predecessor: easier rear access via wide-opening doors and a more versatile load area suit family duties or executive travel.

Despite its size, it navigates city streets better than expected, thanks to rear steering and parking sensors. Fuel tank capacity of 90 liters supports extended ranges over 700 miles.

Performance Benchmarks and Rivals

In comparisons, the Panamera 4S Diesel outpaces luxury peers like the Mercedes S-Class Diesel and BMW 7 Series, offering superior dynamics without sacrificing refinement. Its Nürburgring lap time underscores track credentials, while real-world economy appeals to efficiency-conscious buyers. Against petrol variants like the Panamera 4S (440hp V6), the diesel trades a touch of top-end shove for low-end grunt and better mpg.

Priced from around £91,000, it undercuts some hybrids but demands extras for full spec. Ownership costs include premium fuel (diesel) and maintenance, though Porsche’s reliability reputation holds strong.

Pros and Cons Overview
