Classic & Sports Car – Buyer’s guide: Lagonda 2.6 Litre / 3 Litre

Why you’d want a Lagonda 2.6 Litre / 3 Litre

More than 70 years after its introduction, the Lagonda still elicits gasps of amazement from all who venture under its skin.

This was a seriously advanced car in 1947 – especially in staid-looking 2.6 Litre form – and throughout its production life. With a twin-overhead-cam engine, pure cruciform I-beam chassis, all-independent suspension – wishbones and coils up front, torsion bars to the rear – and rack-and-pinion steering, this was state-of-the-art racing spec. Yet it formed the underpinnings of a fine saloon and drophead in the years of post-war austerity, and was brought to production by a tractor manufacturer…

The secret, of course, was WO Bentley. The brilliant engineer, who introduced aluminium pistons in 1913 and won numerous races before WW2 with his eponymous cars, joined Lagonda in 1935 and, following its pre-war V12, designed the twin-cam ‘six’ for the post-war market.

The Ministry of Supply was unimpressed and it could all have vanished into thin air, if it wasn’t for David Brown. The transmission and tractor maker, who had raced motorcycles and designed his own twin-cam straight-eight in the early ’20s, bought Aston Martin in 1946 but found it desperately lacking in the engine department.

The opportunity to snap up Lagonda the next year – for a mere £52,500 – couldn’t have been better timed. He really only wanted the engine, but realised that the 2.6 Litre was too special to die, and put it into limited production.

That the Lagonda was a very fine car shines through in The Motor’s road test of the 3 Litre: ‘It is one of the very few passenger saloons whose primary appeal is to the skilful and appreciative driver,’ it enthused – though it did comment on a pronounced tendency to oversteer in spite of excellent traction, and a somewhat hard ride.

A special car came at a special price, however, and the Lagonda was very costly compared to mass-produced Jaguars and the like. That said, it was trimmed to an exceptionally high standard throughout, and came with plenty of equipment that would have been optional extras on others, such as a radio, two-speed wipers, windscreen washers, and a comprehensive heating and ventilation system.

Sadly, Frank Feeley’s superbly elegant restyle and the new car’s 104mph top speed failed to reignite Lagonda sales, and production slowed to a halt in 1957.

Lagonda 2.6 Litre / 3 Litre: what to look for

Classic & Sports Car – Buyer’s guide: Lagonda 2.6 Litre / 3 Litre

Though there’s a pre-war feel to the body’s flexibility, it is exceptionally well insulated from chassis noise and vibration. The Lagonda bowls along effortlessly, with a surprising turn of speed from the free-revving twin-cam straight-six. An overdrive conversion gives this example even longer legs for relaxed touring.

Engine

Shared with contemporary Aston Martins, the cast-iron twin-cam engine is set low and well back in the chassis. Check for signs of water and oil mixing (head-gasket or liner-seal failure), for excessive breathing and leaks, and for fore/aft crank movement indicating failed thrust washers. Properly set up, it is durable.

Suspension

Double-wishbone front suspension with anti-dive characteristics was state-of-the-art; regular lubrication is needed to reduce bush/kingpin wear.

Gearbox

The four-speed, three-synchromesh David Brown gearbox is a robust unit, shared with Astons: check all synchros work well and that first isn’t too noisy.

Interior

Luxurious trim was a given: expensive to restore, but lasts if well looked after. This example is all original, with subtle repairs to the driver’s seat.

Timber abounds: check its condition, and that it all matches. Instruments should be complete and original – if present, they can always be rebuilt.


Lagonda 2.6 Litre / 3 Litre: on the road

Classic & Sports Car – Buyer’s guide: Lagonda 2.6 Litre / 3 Litre
Rare two-door 3 Litre is particularly elegant from the rear; advanced spec results in a fine drive, but complex maintenance

In their day, these Lagondas offered lively performance and a comfortable ride. Pre-war body construction methods mean some flex, but the sturdy cruciform chassis keeps the all-independent suspension under control.

By today’s standards, a 2.6 Litre may feel a little staid, but the 3 Litre has an impressive turn of speed and lopes along effortlessly (and remarkably quietly) at the legal limit.

The cast-iron engine (an aftermarket alloy head is available, at a price) is a fine piece of engineering, with wet liners that have to be set up accurately otherwise leaks can occur either from the head gasket or the liner-base seals.

It’s not rocket science, but it’s recommended that engine work is handled by engineers experienced in the Lagonda’s foibles. There is no valve adjustment, clearance being achieved originally by swapping cam followers, but now usually by grinding the valves to length. Hardened seats and stainless-steel valves improve durability on unleaded.

The gearbox is a sturdy David Brown unit, with column change until 1955, though this car (and many others) has since been converted to a more familiar floor change. Installing a later 3-litre engine into a 2.6 is not uncommon, and should not detract from value.

Rust is the killer, because the entire floorpan, bulkheads and rear inner wings are steel; the ash body frame also rots away. Parts are available from the very keen Lagonda Club and Aston Service Dorset, plus stashes of used spares.

The owner’s view

Classic & Sports Car – Buyer’s guide: Lagonda 2.6 Litre / 3 Litre
Owner Peter Gilkes rebuilt his 3 Litre saloon

Peter Gilkes’ 3 Litre two-door saloon has been in the family for 34 years: “It was my father’s retirement project; we bought it at the Ellard auction of Lagonda projects and rebuilt it together over eight years. The interior is original except for the carpets and the body was done professionally, but we did the mechanicals.

“When we stripped the engine, the thrust washers were broken but it was largely unworn. The body was good apart from the lower rear wings, which were full of filler. It’s been on the road for 26 years now and does around 2000 miles a year.

“It’s a great touring car: we’ve been to Ireland, the Dordogne, Shetland, the Orkneys and Le Mans. I’ve fitted Simon Constable’s overdrive conversion, which fits in place of the torque tube in front of the diff and is brilliant.”
