Overview

The 2017 Mercedes-Benz AMG GT is a front-engine, rear-wheel-drive two-door grand touring sports car positioned as a more usable alternative to mid-engine supercars while still delivering serious track-capable performance. It’s ideal for drivers who want AMG character, premium cabin materials, and a distinctive long-hood design without giving up day-to-day comfort. For 2017, the AMG GT lineup continues in the same generation introduced for 2016, with refinements and a broader range that includes the higher-output GT S and the track-focused GT R. In the market, it competes with cars like the Porsche 911 and Audi R8, leaning toward torque-rich V8 muscle and luxury.

Key Features

1) Handbuilt AMG 4.0L twin-turbo V8 (M178): 2017 AMG GT models use a dry-sump-style lubrication approach with a “hot inside V” turbo layout for fast response and strong midrange pull. 2) Power options by trim: AMG GT produces about 456 hp, AMG GT S about 503 hp, and the AMG GT R jumps to roughly 577 hp, with substantial torque across the range. 3) 7-speed AMG SPEEDSHIFT dual-clutch transmission (DCT): Delivers quick shifts and a sporty feel, with multiple drive modes that change shift strategy and throttle response. 4) Performance chassis hardware: Adaptive damping (available/standard depending on trim), large performance brakes, and wide rear tires help the GT feel planted at speed; the GT R adds more aggressive aero and track-oriented calibration. 5) Premium grand touring cabin: Supportive sport seats, high-quality trim, and a driver-focused center stack give it a special feel, though storage space is limited compared with a sedan or coupe hatch.

Common Issues & Reliability

Shoppers searching “2017 Mercedes-Benz AMG GT reliability” should know that many owners report strong overall durability when the car is maintained properly, but a few repeat issues show up across forums, service records, and complaint patterns. 1) Cooling system leaks and level warnings: Some owners report coolant odor, low-coolant warnings, or leaks from hoses, clamps, or the water pump area, sometimes appearing in the 20,000–50,000 mile range. Addressing small leaks early helps prevent overheating and secondary damage. 2) DCT drivability issues (jerky shifts or hesitation): The 7-speed DCT can feel abrupt at low speeds by nature, but complaints sometimes describe worsening hesitation, harsh engagement, or lurching that may be improved with software updates, adaptation resets, or fluid service. If symptoms persist, diagnosis can involve mechatronic controls or clutch-related calibration. 3) Electrical and infotainment glitches: Owners occasionally report intermittent sensor warnings (parking sensors, camera issues, tire pressure alerts) or COMAND/infotainment bugs. Many are resolved with software updates, battery health checks, or repairing a faulty sensor rather than a major component failure. 4) Premature wear items from high performance: Brakes and tires can wear quickly, especially on GT S and GT R models driven aggressively. Expect faster consumption of rear tires and potentially noisy or warped-feeling brakes if the car sees repeated hard stops without proper bedding or cooldown.
