The McLaren 675LT Spider, produced from July 2016 to March 2017, represents a focused, high-performance iteration of the McLaren 650S. Positioned as a limited-production model, the 675LT Spider aimed to deliver a more visceral and track-focused driving experience compared to its more grand-touring oriented sibling. The “LT” designation, harking back to McLaren’s “Longtail” heritage from the 1990s, signified extensive weight reduction, increased power, and enhanced aerodynamics. It slots into the McLaren lineup as a premium, performance-focused roadster, appealing to enthusiasts seeking a thrilling and exclusive driving experience. The 675LT Spider is built on the MonoCell chassis, a carbon fiber monocoque construction that provides exceptional rigidity and lightweight properties.

Powertrain & Engine Architecture
At the heart of the 675LT Spider lies McLaren’s M838T 3.8-liter twin-turbocharged V8 engine. This engine is a derivative of the powerplant found in the 650S, but with significant enhancements. These include revised turbochargers, a redesigned cylinder head with optimized porting, and a reduced compression ratio. These modifications contribute to the increased power output of 675 horsepower and 700 Nm (516 lb-ft) of torque. The engine utilizes direct fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) to optimize performance and efficiency. The ‘SSG’ transmission is a seven-speed dual-clutch gearbox, specifically tuned for faster shift times and a more engaging driving experience. It’s not a traditional automatic, but rather a highly sophisticated automated manual transmission.
Driving Characteristics
The 675LT Spider delivers a remarkably focused and exhilarating driving experience. The combination of the increased power, reduced weight (approximately 100 kg lighter than the 650S Spider), and revised aerodynamics results in blistering acceleration and exceptional handling. The SSG transmission provides incredibly rapid gear changes, contributing to the car’s impressive performance. Compared to the standard 650S Spider, the 675LT Spider feels significantly more responsive and agile. The suspension is firmer, providing greater control during spirited driving, but at the expense of some ride comfort. The exhaust note is also more aggressive, adding to the overall sensory experience. The gear ratios are optimized for acceleration, making the car feel incredibly potent in the mid-range.
Equipment & Trim Levels
The 675LT Spider was offered with a relatively high level of standard equipment, reflecting its premium positioning. Standard features included carbon fiber body panels, lightweight Alcantara interior trim, a bespoke exhaust system, and a sophisticated infotainment system. Customers could further personalize their vehicles through McLaren’s extensive options catalog, which included a variety of exterior paint colors, interior upholstery choices, and performance upgrades. Optional extras included a rearview camera, parking sensors, and a premium audio system. The interior focused on minimizing weight, with carbon fiber extensively used throughout the cabin.
Chassis & Braking
The 675LT Spider utilizes a carbon fiber monocoque chassis, providing exceptional rigidity and lightweight construction. The suspension features double wishbones at both the front and rear, with adaptive dampers to adjust to varying road conditions. Braking is handled by ventilated discs at all four corners, providing ample stopping power. The car is equipped with an anti-lock braking system (ABS) and electronic stability control (ESC) to enhance safety. The steering is a rack and pinion system with electric power assistance, offering precise and responsive control.
Market Reception & Comparison
The McLaren 675LT Spider was widely praised by automotive critics for its exceptional performance, handling, and exclusivity. Reviewers consistently highlighted the car’s engaging driving experience and its ability to deliver a visceral connection to the road. Compared to the 650S Spider, the 675LT Spider was considered a more focused and rewarding machine for serious driving enthusiasts. While fuel economy wasn’t a primary concern for buyers in this segment, the 675LT Spider offered reasonable efficiency for its performance level. Reliability reports have been generally positive, although the complex powertrain and advanced technology require specialized maintenance.
Legacy
The McLaren 675LT Spider remains a highly sought-after collector’s item. Its limited production run and exceptional performance have ensured its enduring appeal. The powertrain, while requiring careful maintenance due to its complexity, has proven to be relatively reliable when properly cared for.
