The apex air-cooled 911 reimagining — F1 engineering meets the 964.
The DLS — Dynamics and Lightweighting Study — is the Singer Vehicle Design programme developed in partnership with Williams Advanced Engineering, based on the Porsche 964 platform. Its 4.0-litre naturally aspirated air-cooled flat-six was developed by Williams with input from Hans Mezger, producing 500 hp at a 9,000 rpm redline. Body panels, chassis details and interior fittings extensively use carbon fibre, magnesium and titanium; kerb weight is approximately 990 kg. Drive is through a Hewland six-speed manual gearbox.
Production is limited to 75 units, built in the United Kingdom, at approximately US$1.8M each. The DLS Turbo (2023, based on the 964 Turbo, approximately 99 units, 3.8-litre twin-turbo flat-six producing 700+ hp) is a separate reimagining programme within the Singer catalogue and is referenced here for context only.
The DLS is the apex of the air-cooled 911 reimagining category. Its collaboration with Williams Advanced Engineering — a Formula 1 engineering house — combined with the Mezger-informed 4.0-litre flat-six, made it the technical high-water mark of the Singer catalogue at launch and one of the most engineered restomod programmes ever offered.
| Variant | Years | Production | Notes |
|---|---|---|---|
| DLS (Dynamics and Lightweighting Study) | 2018– | — | Porsche 964 platform; 4.0L naturally aspirated air-cooled flat-six developed by Williams Advanced Engineering with input from Hans Mezger; 500 hp at 9,000 rpm; Hewland 6-speed manual, RWD; carbon-fibre / magnesium / titanium construction; approximately 990 kg. Production limited to 75 units, built in the UK, approximately US$1.8M each. Verify delivery progression. |
| DLS Turbo (reference — separate programme) | 2023– | — | Separate Singer reimagining programme based on the 964 Turbo. 3.8L twin-turbo flat-six, 700+ hp; approximately 99 units. Reference variant only — not folded into the 75-unit DLS run. Verify. |
Modern hypercars are allocation-driven. Verify build slot, factory client-register status, delivery paperwork and specification against factory documentation. For the DLS, verify build slot, specification and delivery status via Singer Vehicle Design. Cars are commissioned individually — the specification and colour choices materially affect resale positioning.
A proper pre-purchase inspection covers cold-start behaviour, hybrid-system health where applicable, undertray-off chassis inspection, brake and tyre condition, and — for track-oriented cars — a review of consumable and lifed-component status. Factory or authorised inspection is strongly preferred over independent assessment.
Use a paint-depth gauge and a lift inspection. Confirm PPF history and any accident record; low-mileage cars still show stone-chip and track-debris damage that materially affects presentation and pricing.
Specification, colour and factory options move values meaningfully. On programme cars, evaluate the ownership experience — support, transport, event access — alongside the car itself.

New ~$1.8M. Trades largely privately and via sealed-bid sales; RM Sotheby's offered exceptional near-delivery-mileage commissions (e.g. the sub-120 km 'Oppenheimer Commission') at $3.25M–$3.75M / £2.6M–£3.0M estimates in 2025 — roughly double the build price. Only 75 built.
