2014 Tesla P85 Used Review: Range, Battery Health & Ownership Costs

Quick Verdict: A Performance Bargain With Battery Caveats

The 2014 Tesla Model S P85 remains one of the most compelling used electric vehicles on the market. Originally priced around $101,000 new, examples now trade between $18,000 and $30,000 depending on mileage, battery health, and condition. The P85's 416-horsepower rear-wheel-drive powertrain still delivers supercar-rivaling acceleration, and access to Tesla's Supercharger network gives it a practical edge over other 2014-era EVs.

But buying a decade-old EV hinges almost entirely on one component: the battery. The 85 kWh NMC pack has proven reasonably durable, but most 2014 P85s will show 10–20% degradation by now, and some may need a replacement that costs $12,000–$20,000. This review breaks down exactly what to expect from range, charging, ownership costs, and whether the P85 still makes sense against modern alternatives.

Range, Efficiency & the Battery Degradation Reality

The 2014 P85 carries an 85 kWh lithium-ion battery pack using NMC (nickel-manganese-cobalt) chemistry. When new, the EPA rated it at 265 miles of combined range — impressive for 2014 and still respectable today.

However, NMC batteries degrade with time, heat exposure, and charge cycles. Based on long-term fleet data and owner surveys, a typical 2014 P85 battery retains roughly 80–90% of its original capacity after 100,000–120,000 miles. That translates to roughly 210–240 miles of usable range on a full charge for a well-maintained example.

Efficiency was rated at 89 MPGe combined (38 kWh per 100 miles) when new. Real-world efficiency varies: expect 34–40 kWh/100 mi depending on driving style, climate control use, and ambient temperature. The P85's single rear motor and heavy curb weight (~4,600 lbs) make it less efficient than modern dual-motor EVs with heat pumps and silicon-carbide inverters.

Charging Speeds: Supercharger Access Is the P85's Trump Card

Charging infrastructure separates the 2014 P85 from nearly every other used EV of its era. Tesla's proprietary Supercharger network — now increasingly open to other brands via NACS adoption — remains the most reliable DC fast-charging network in the U.S.

The P85's onboard charger accepts up to 10 kW on Level 2 (single charger) or 20 kW with the optional dual-charger configuration. Most 2014 P85s were ordered with dual chargers, but verify this before purchase — it significantly impacts home charging speed.

On Tesla Superchargers, the P85 peaks around 120 kW but sustains that rate only briefly. The charge curve tapers noticeably above 60% state of charge (SoC), and you'll see rates drop to 40–60 kW above 80%. A typical 10–80% session takes about 40 minutes. This is slower than modern 800V EVs that achieve 10–80% in 18 minutes, but it's adequate for road-trip stops.

Important note: The 2014 P85 uses Tesla's proprietary connector (now called NACS). It can charge at any Tesla Supercharger and any destination charger with the Tesla connector. For CCS-based public chargers (Electrify America, EVgo CCS stalls), you'll need an adapter — and DC fast charging via CCS adapters on older Teslas has limited compatibility. CHAdeMO adapters exist but are slow and increasingly obsolete.

Performance: Still Quick, Still Refined

The "P" in P85 stands for Performance, and the numbers back it up. The single rear-mounted AC induction motor produces 416 horsepower and 443 lb-ft of torque, delivering instant, linear acceleration that still feels urgent in 2026.

The 0–60 mph sprint takes 4.2 seconds — quick enough to embarrass most gas-powered sedans from the same era. The P85 lacks the dual-motor all-wheel-drive traction of later P85D and P90D models, so launch grip depends on tire condition and road surface. On wet pavement, you'll feel the rear wheels break traction before the electronic stability control intervenes.

Ride quality is a highlight. The 2014 Model S uses a sophisticated multi-link rear suspension and adaptive air suspension (standard on P85). At highway speeds, it settles into a comfortable, quiet cruise. The air suspension can raise for driveways and speed bumps or lower for aerodynamic efficiency. However, air suspension failures are a known issue on 2012–2016 Model S vehicles — budget $1,500–$2,500 per corner if struts need replacement.

Interior, Tech & Driver Assistance

The 2014 Model S interior was ahead of its time with the massive 17-inch touchscreen that controls nearly every vehicle function — climate, navigation, media, suspension settings, and software updates. The minimalist design has aged well visually, though the hardware underneath is now dated.

Infotainment and software: Early 2014 P85s shipped with the MCU1 (NVIDIA Tegra 3) processor, which feels sluggish by modern standards. Tesla offered an MCU2 upgrade (Intel Atom) for ~$2,000–$2,500, which dramatically improves responsiveness and enables newer software features. Many 2014 P85s have received this upgrade — confirm with the seller. Without MCU2, you won't get features like Sentry Mode dashcam recording, Theater mode, or the latest navigation visuals.

Driver assistance: The 2014 P85 predates Tesla's Autopilot hardware suite (introduced late 2014 for 2015 models). Most 2014 P85s have no advanced driver assistance beyond basic cruise control, ABS, and stability control. A few late-2014 build P85s may have the first-generation Autopilot hardware (AP1), but this is rare. If you want Autopilot or FSD capability, look at a 2015+ Model S instead.

Passenger and cargo space: The Model S seats five adults comfortably, with 38.1 inches of rear legroom. The rear hatch opens to 26.3 cubic feet of cargo space, expanding to 58.1 cu ft with rear seats folded. The front trunk (frunk) adds 5.3 cu ft. Some 2014 models were optioned with rear-facing jump seats in the cargo area for two small children, making it a 7-seater — a rare and desirable configuration for families.

Pricing, Tax Credits & Ownership Costs

The 2014 Tesla Model S P85 originally carried an MSRP of approximately $101,000 (before any incentives). In the 2026 used market, prices have settled into a far more accessible range:

Federal tax credit eligibility: Under IRS §30D rules, the federal clean vehicle credit applies only to new qualifying vehicles or to used EVs under the separate §25E used clean vehicle credit. Here's how that applies to a 2014 P85:

• §30D New Vehicle Credit ($7,500): Not applicable — this is a used vehicle.
• §25E Used Clean Vehicle Credit (up to $4,000): Potentially eligible. Requirements include: sale price under $25,000, purchased from a licensed dealer, buyer income under $75,000 (single) / $150,000 (joint), and the vehicle must be at least two model years old (the 2014 qualifies). The credit equals 30% of the sale price, capped at $4,000. A P85 purchased for $18,000 from a dealer could yield a $4,000 credit; one purchased for $28,000 would not qualify due to the $25,000 price cap.
• Point-of-sale transfer: The §25E credit can be transferred to the dealer at the point of sale, reducing your out-of-pocket cost immediately.
• State incentives: Vary by jurisdiction — check your state's energy office or DSIRE database for local rebates.

Insurance costs: Expect $1,800–$3,000 annually for a 2014 P85, depending on your driving record, location, and coverage level. Tesla vehicles generally carry higher premiums due to repair costs and aluminum body panels. Get quotes before purchasing.

Maintenance and common repairs: The P85 has no engine oil, transmission fluid, or spark plugs, but it isn't maintenance-free. Budget for: tire replacement every 20,000–30,000 miles ($800–$1,400 for a set), brake fluid flush every 2 years, cabin air filter replacement, 12V battery replacement every 3–5 years (~$300), and potential air suspension repair ($1,500–$2,500 per corner). The drive unit (motor) has proven reliable but can fail — replacement runs $3,000–$5,000.

Warranty Status in 2026

The 2014 P85 originally came with a 4-year/50,000-mile basic warranty and an 8-year/unlimited-mile battery and drive unit warranty. Tesla's 8-year battery warranty on 85 kWh models guaranteed the battery would retain at least 70% of its original capacity.

By 2026, virtually all 2014 P85s have exceeded both warranty periods. The 8-year battery warranty expired in 2022 at the latest. Any battery failure or significant degradation is now an out-of-pocket expense unless you purchase an extended warranty from a third-party provider (availability varies).

Tesla offers battery replacement services at its service centers. A refurbished 85 kWh pack currently costs $12,000–$16,000 installed, while a new or higher-capacity pack (if available) can cost $18,000–$22,000. Some third-party EV shops also perform battery replacements or module-level repairs at lower cost.

2014 P85 vs. the Competition: What Else Can You Buy?

At $18,000–$30,000, the 2014 P85 competes with newer used EVs and even some new budget EVs. Here's how it compares:

Who Should Buy the 2014 Tesla P85?

The 2014 P85 is best suited as an enthusiast's daily driver or a second car for someone who understands EV ownership. It rewards buyers who do their homework — get a pre-purchase inspection at a Tesla Service Center, pull battery health logs from the car's diagnostic menu, and budget for the inevitable age-related repairs.
