Real-World Driving Experience & User Feedback of the Tesla Model S P85D

The Tesla Model S P85D represents a pivotal iteration in Tesla’s performance lineup, blending dual-motor all-wheel-drive capability with a refined driving experience that bridges raw power and everyday usability. Unlike its more aggressive successors—the P90D and Plaid—its 670 hp output and balanced power delivery make it a compelling choice for enthusiasts seeking a high-performance EV without the extreme demands of a track-focused machine. User feedback and real-world testing reveal nuanced insights into its auditory, tactile, and ergonomic qualities, as well as long-term reliability considerations that distinguish it from both its predecessors and contemporaries.

The P85D’s driving dynamics are shaped by its dual-motor AWD system, which prioritizes torque vectoring and regenerative braking finesse over outright speed. Its interior, while sharing Tesla’s signature minimalism, reflects early-stage evolution in the brand’s infotainment philosophy, offering a blend of innovation and quirks that owners either embrace or critique. Below, structured analyses of owner-reported experiences, technical feedback, and comparative performance metrics provide a comprehensive overview of the P85D’s practical and emotional appeal.


Auditory and Tactile Feedback During Acceleration

The P85D’s acceleration profile is defined by a progressive, multi-stage power delivery that distinguishes it from the linear thrust of the P90D or the abrupt torque surge of the Plaid. Auditory feedback during launches is characterized by:

9. A low, guttural whine from the dual motors, more pronounced than the P85’s single-motor variant but less aggressive than the P90D’s higher-revving induction motors.
10. Tire roar at higher speeds, amplified by the P85D’s wider 22-inch wheels (standard) and sticky Michelin Pilot Super Sport tires, which emphasize grip over outright noise.
11. A subtle "whoosh" from the active aerodynamics system (adjustable rear spoiler and front air flaps) engaging at ~60 mph, providing tactile confirmation of downforce deployment.

Tactile feedback during acceleration is seat-of-the-pants oriented, with owners frequently describing:


12. A pronounced "shove" into the seat during hard launches, particularly in lower gears, due to the 670 hp pushing ~4,500 lbs (curb weight). This is less abrupt than the Plaid’s 1,020 hp but more deliberate than the P85’s single-motor hesitation.
13. Motor braking engagement during gear shifts (especially in Ludicrous Mode), where regenerative braking briefly counters acceleration before the motors re-engage, creating a rhythmic "chop" in throttle response.
14. A noticeable weight transfer during aggressive launches, with the rear end lifting slightly before settling into a planted stance—a trait more evident in the P85D than in the Plaid, which prioritizes rear-biased torque distribution.

Comparison to contemporaries:


15. P90D: Higher-pitched motor whine and a more linear, less "staged" power delivery.
16. Plaid: A deeper, more aggressive growl with a sharper torque surge, often described as "like a rocket leaving the pad."
17. BMW i8 (hybrid competitor): A more refined, high-revving ICE-like character, but with less low-end torque authority.

Handling, Braking, and Cornering: Owner-Reported Themes

The P85D’s chassis tuning reflects Tesla’s early efforts to balance AWD dynamics with a neutral, predictable handling character, though owner feedback highlights both strengths and idiosyncrasies. Below are structured observations from real-world driving experiences:

Handling Characteristics
The P85D’s 2150 mm wheelbase and low center of gravity (1.37m) contribute to a neutral-to-slightly understeer bias, which owners report as:


18. Highly predictable in everyday driving, with minimal body roll and a tense, connected feel through the steering wheel (15.5:1 ratio).
19. Responsive to steering inputs, though some owners note a slight delay in rear-end rotation during aggressive mid-corner throttle application, particularly on high-grip surfaces.
20. Oversteer tendencies in extreme conditions (e.g., wet pavement or sudden throttle inputs), though less pronounced than in the P90D, which lacks the P85D’s torque vectoring refinement.

Braking Performance
Regenerative braking is a defining feature of the P85D, with owners emphasizing:


21. One-pedal driving precision, where low-speed regenerative braking (Level 1–2) feels proportional and predictable, mimicking traditional brake modulation.
22. High-speed braking responsiveness, with minimal lag between pedal input and deceleration, though some report a brief "pulse" in the steering wheel during hard stops due to torque vectoring adjustments.
23. Audible motor whine during aggressive regenerative braking, which some find immersive while others describe it as distracting in urban environments.

Cornering Dynamics
The P85D’s adaptive damper system and torque vectoring (via rear-wheel braking) create a dynamic cornering experience, with key observations:


24. Mid-corner throttle application yields rear-end traction benefits, though excessive input can trigger subtle oversteer, particularly on rear-wheel-drive-biased surfaces.
25. High-speed cornering stability is praised for minimal body squat or lift, with owners noting a "glued-to-the-pavement" feel at speeds exceeding 100 mph.
26. Limit handling is not the primary strength; while the P85D can be pushed to its ~0.90 g lateral limit (as measured by independent tests), it lacks the Plaid’s aggressive rear-biased torque distribution for track-focused driving.

Common Owner Adjustments


27. Lowering springs (aftermarket) to reduce body roll and improve cornering precision.
28. Customizing torque vectoring via Tesla’s Suspension Settings (e.g., reducing rear-brake bias for understeer-prone drivers).
29. Disabling "Traffic-Aware Cruise Control" to mitigate unexpected regenerative braking in stop-and-go traffic.

Interior Features and Minimalist Design Philosophy

The P85D’s interior embodies Tesla’s 2015-era minimalist design philosophy, prioritizing functionality over tactile luxury while laying the groundwork for future iterations. Key observations from owner feedback include:

Infotainment and Controls


30. 17-inch touchscreen (2016+ models) replaces the earlier 12.3-inch display, offering improved legibility but retaining laggy responsiveness during complex navigation or media playback.
31. Common complaints:
32. Delayed touch recognition in cold weather or during rapid screen transitions.
33. Software bugs (e.g., random app crashes, Bluetooth pairing failures) that persist across multiple firmware updates.
34. Owner workarounds:
35. Using voice commands for critical functions (e.g., "Set temperature to 72") to avoid screen interaction.
36. Disabling animations in Tesla’s Developer Mode to reduce lag.
37. Physical buttons (e.g., steering wheel stalks, gear shifter) are minimalist but functional, with the single paddle shifter offering only forward/reverse selection—a limitation for performance driving.
38. Center console features:
39. A single cup holder (a recurring joke among owners) and no physical climate controls, relying entirely on the touchscreen.
40. Ambient lighting (optional) is bright and monochromatic, lacking the Plaid’s RGB customization.

Seating and Ergonomics


41. Heated, ventilated seats are highly praised for comfort on long drives, though lateral support is thin compared to competitors (e.g., BMW 7 Series).
42. Adjustable steering wheel (tilt and reach) is functional but lacks memory presets, a feature later added to the Plaid.
43. Pedal feel is firm and direct, with regenerative braking pressure adjustable via one-pedal driving settings.

Build Quality and Materials


44. Interior materials are mixed: Premium leather on seats and dashboard contrasts with hard plastics on door panels and center console.
45. Haptic feedback (e.g., door unlock/lock) is subtle but effective, though no physical feedback for gear selection.
46. Noise, vibration, and harshness (NVH) are better than contemporaries (e.g., early Jaguar I-Pace), with minimal wind noise at highway speeds.
