Super Series Longtail revival — extreme aero, 666 bhp and a deliberately tiny production run.
.jpg?width=1600)
The 675LT (2015) was McLaren's first modern Longtail and the most aggressive evolution of the 650S/12C platform. Power rose to 666 bhp (675 PS), the body was lengthened with a longer front splitter, side blades and active rear airbrake, and the car was lightened by 100 kg through carbon panels, titanium exhaust and lighter wheels and brakes. Production was capped at 500 coupes; an LT Spider followed in 2016 with 500 examples.
McLaren's Longtail naming references the original F1 GTR Longtails of 1997, and the 675LT cemented LT as a collector designation on every Super Series car since.
The car that re-established 'LT' as a McLaren collector badge — sold out almost instantly and consistently the most desirable 12C-derived car.
| Variant | Years | Production | Notes |
|---|---|---|---|
| 675LT Coupe | 2015–2016 | 500 | Capped production; sold out. |
| 675LT Spider | 2016 | 500 | Folding hard-top; same power and chassis spec. |
Start with identity, paperwork and originality. For the McLaren 675LT, the strongest cars have continuous ownership history, matching numbers where applicable, original books and tools, factory build documentation and evidence of work by manufacturer-approved specialists. Original paint, MSO Defined carbon, low mileage and the original delivery file (build slip, MSO documents).
M838T 3.8 twin-turbo V8 with LT-specific internals; coolant lines, turbo actuators and titanium exhaust system are the recurring inspection points. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history (where applicable), leak-down or compression testing, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.
Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps and finish standards. Collector value is dramatically affected by structural repairs, refinished panels, poor paintwork and missing factory trim or option content. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.
Verified one of 500 coupe or 500 spider, with documented McLaren Qualified history, MSO carbon and original wheels. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, rather than a tired example of a rarer derivative that will need years of corrective work.
Regional ranges authored independently — each reflects its local market, not an FX conversion
Budget annually even if the car is used sparingly. Fluids age, tyres and date-coded rubber components must be replaced regardless of mileage, and stored cars need exercise. A documented maintenance rhythm protects both reliability and resale value.
McLaren Qualified network only; LT-specific aero panels and titanium exhaust components are not parts catalogue items for generalist shops. Before purchase, confirm parts availability for model-specific bodywork, electronics, gearbox and engine components. A discounted car waiting on unobtainable parts or a factory service slot is rarely a saving in collector ownership.
Each region quoted in its local currency — independent market readings, not FX conversions
After a strong run, the 675LT has settled into a defined collector range. Coupes lead Spiders; original paint, documented McLaren Qualified history and the original delivery file are decisive.

Capped production, defining Longtail badge and the last analogue Super Series McLaren before the Senna era — best examples should remain firm.
