What car has the best automatic gearbox?

There isn’t a single winner for every driver or situation: for pure performance, the Porsche 911’s PDK is the standout; for all‑round everyday brilliance, the ZF 8‑speed in cars like the BMW 3/5 Series is hard to beat; for smooth, durable urban driving, Toyota and Lexus hybrids with e‑CVT lead; for luxury cruising, Mercedes’ 9G‑Tronic shines; and among EVs, the Porsche Taycan’s two‑speed rear gearbox is the current benchmark. The right choice depends on whether you prioritize shift speed, refinement, efficiency, towing, or long‑term reliability.

How “best” is judged

Evaluating an automatic gearbox comes down to several factors: shift speed and consistency, low‑speed refinement, intelligent software that picks the right gear without hunting, efficiency at highway speeds, reliability and heat management, and how well the transmission integrates with the engine or motors. Different designs—torque‑converter autos, dual‑clutch transmissions (DCTs), continuously variable transmissions (CVTs), hybrid e‑CVTs, and single- or two‑speed EV units—excel in different roles.

Standout gearboxes and the cars that use them (2025)

The following pairings highlight widely praised transmissions and representative current models, reflecting how they perform in real‑world driving and ownership today.

• Porsche 911/718 with PDK (8‑speed dual‑clutch): Blisteringly fast, near‑telepathic shifts on road and track, yet calm and predictable in traffic. The latest 911 PDK integrates hybrid assistance in the 2025 911 GTS while retaining its trademark response.
• ZF 8‑speed torque converter (8HP) in BMW 3/5 Series, Audi A6/A8/longitudinal Quattro models, Alfa Romeo Giulia, and many Jeeps/RAMs: The all‑rounder. Smooth at low speeds, quick under load, smartly calibrated and efficient; newer mild‑hybrid versions add seamless stop/start.
• Mercedes‑Benz 9G‑Tronic (9‑speed torque converter) in S‑Class/E‑Class/GLC: Exceptional refinement with long gearing for quiet, low‑RPM cruising and strong fuel economy, plus intuitive downshifts when you need power.
• Toyota/Lexus e‑CVT hybrids (planetary‑split) in Camry Hybrid, RAV4 Hybrid, Lexus ES/RX hybrids: Seamless and robust for commuting, with low maintenance and proven longevity; not a belt CVT, so durability is a strong suit.
• Porsche Taycan two‑speed rear transmission (also in Audi e‑tron GT): Unique among modern EVs, delivering explosive launches and superior high‑speed efficiency/acceleration compared with single‑speed rivals.
• Ford/GM 10‑speed automatic (10R80/10L80) in Ford F‑150, Chevrolet Silverado/GMC Sierra: Broad ratio spread for towing and economy; recent calibrations are smoother and keep engines in the sweet spot under load.
• Ferrari/McLaren 8‑speed DCTs (Ferrari 296 GTB/SF90, McLaren Artura): Lightning shifts and aggressive logic for supercar duty while maintaining decent town manners thanks to wet clutches and refined control software.
• Volkswagen/Audi DSG (DQ381 wet‑clutch) in Golf R, GTI, Audi S3: Rapid, engaging shifts in compact performance cars; can exhibit low‑speed shudder in stop‑start traffic, but recent tunes are improved.
• Toyota Direct‑Shift CVT (Corolla) with launch gear: Uses a physical first gear for clean getaways, then hands off to the belt CVT, mitigating the “rubber‑band” feel common to CVTs.

Taken together, these picks underscore a pattern: Porsche’s PDK sets the pace for outright performance, ZF’s 8HP is the most versatile for mixed driving, e‑CVTs dominate for city smoothness and reliability, Mercedes’ 9G‑Tronic rules for luxury refinement, and Porsche’s two‑speed Taycan hardware stands out among EVs.

Which “best” matches your use case?

Performance driving

If lap times, mountain passes, and precision are your world, Porsche’s PDK (911/718) remains the class reference for speed and intuition. Ferrari’s and McLaren’s latest wet‑clutch DCTs rival it for ferocity, while BMW’s M models using the latest ZF 8HP prove a modern torque converter can deliver track‑ready response with less low‑speed fuss than many DCTs.

Daily comfort and longevity

For commuters who value seamless take‑off, smooth crawling, and low stress ownership, Toyota/Lexus hybrid e‑CVTs and mainstream ZF 8HP applications are standouts. The e‑CVT’s simplicity and Toyota’s conservative thermal management pay dividends over high‑mileage use, while ZF’s widespread support and parts availability make it a safe bet across many brands.

Luxury cruising

Long‑distance comfort favors longer gearing and creamy shifts. Mercedes’ 9G‑Tronic in the S‑Class and E‑Class is exceptionally quiet and efficient at highway speeds, with well‑timed downshifts for quick overtakes. High‑end ZF 8HP calibrations in BMW 5/7 Series and Audi A8 are close behind.

EVs

Most electric cars use single‑speed reduction gears that feel ultra‑smooth but can taper at very high speeds. Porsche’s Taycan (and Audi e‑tron GT) add a two‑speed rear gearbox: short first for brutal launches, tall second for top‑end punch and efficiency—currently the most sophisticated EV “automatic” feel on sale.

Towing and trucks

Ford and GM’s co‑developed 10‑speed keeps petrol and diesel trucks in the torque band under load while reducing revs on the highway. Calibrations in recent F‑150s and Silverados are notably smoother than early iterations, with better shift scheduling on grades.

Key gearbox technologies explained

Understanding the hardware helps explain why different cars feel the way they do and why “best” varies by scenario.

• Torque‑converter automatics: Fluid coupling smooths engagement; modern units (ZF 8HP, Mercedes 9G‑Tronic) lock up early for efficiency and now shift nearly as fast as DCTs in many cases.
• Dual‑clutch transmissions (DCT): Two clutches pre‑select gears for instant changes and direct feel; can be jerky at parking speeds if tuning and clutch cooling aren’t top‑notch.
• CVTs: Belt‑and‑pulley design offers stepless ratios and stellar efficiency; can feel droney. Toyota’s Direct‑Shift CVT adds a first gear to improve launches.
• Hybrid e‑CVTs: Planetary gearsets blend engine and motor power without belts; renowned for smoothness and durability, especially in Toyota/Lexus systems.
• EV single/two‑speed: Single‑speed gear reduction is simple and smooth; Porsche’s two‑speed adds versatility for both launches and high‑speed performance.

The net effect: torque converters win for broad usability, DCTs rule for maximum engagement, e‑CVTs dominate for urban serenity and longevity, and multi‑speed EV drives expand electric performance envelopes.

How to choose on a test drive

Beyond spec sheets, the best way to pick your “best” automatic is to feel how calibration and hardware work together in your driving environment.

• Assess low‑speed behavior: creeping in traffic, parking maneuvers, and stop/start restarts.
• Try mixed conditions: hill climbs, downhill engine braking, and rapid merges.
• Check kickdown logic: how quickly and smoothly the car finds power for overtakes.
• Use manual mode: responsiveness to paddle inputs and willingness to hold gears.
• Watch temperatures on a spirited route or with a trailer: consistent performance matters.
• Listen and feel: drone, hunting, or shudder indicate tuning compromises you may not want to live with.

If a gearbox feels transparent in daily use yet decisive when pushed, you’ve likely found the right match for your priorities.

Bottom line

For outright brilliance, Porsche’s PDK is the benchmark; for everyday excellence across brands and budgets, ZF’s 8‑speed is the safest recommendation; for set‑and‑forget smoothness and durability in city life, Toyota/Lexus hybrid e‑CVTs are leaders; for luxury highway miles, Mercedes’ 9G‑Tronic is a gem; and for EVs, the Porsche Taycan’s two‑speed solution is the most advanced. The “best” automatic gearbox is the one that aligns with how and where you drive.

What car company makes the best automatic transmission?

Toyota: Toyota’s automatic transmissions are widely regarded for their longevity. Models like the Toyota Camry and Corolla have a reputation for reliability. Honda: Honda’s automatic transmissions, particularly in models like the Accord and Civic, are known for their durability and low maintenance.

What is the number one killer of automatic transmissions?

At the top of all auto repair experts lists for causes of problematic transmissions is low transmission fluid. Usually caused by a leak somewhere in the system, low or contaminated fluid makes it nearly impossible for the transmission to automatically shift gears and run smoothly.
