Delage D8 (1929)
(Translator’s note: This article is the second part. The previous models were introduced in the first part.)
After creating a highly successful 1.5L supercharged in-line eight-cylinder engine for Grand Prix cars in 1926, Delage launched a 4.1L naturally aspirated engine with the same configuration in their luxury model, the D8.

The D8 was manufactured until 1940 when Delage was acquired by Delahaye. The D8 featured various straight-eight engines, with displacements ranging from 2.6L to 4.7L for reasons like performance enhancement and tax regulations.
Hillman Straight Eight (1929)
The 2.6-liter Hillman straight-eight was a formidable competitor to the eight-cylinder version of the Wolseley 21/60; however, it was costly and quickly gained a reputation for bearing failures, resulting in poor sales.
An update that renamed it the Vortic was not beneficial either: the Straight Eight remained available until 1932, when production ceased, as it aimed to clear out existing inventory.

Lanchester 30hp (1929)
The Lanchester’s sole inline-eight engine was a 4.4-liter overhead camshaft unit producing 30 horsepower. Like many vehicles of that era, it was not a popular purchase during the Great Depression, with fewer than 100 units manufactured.
Production continued after 1930, but Lanchester was acquired by the BSA Group and partnered with the British (rather than German) Daimler.

Roosevelt (1929)
The perception that cars with inline-eight engines had to be expensive, or at least mid-range, was shattered with the launch of the 3.3L Roosevelt, the only model from a sub-brand established by Marmon that produced inline-eight engines.
Notably, the Roosevelt was priced at just $995, while the Marmon 68 and Marmon 78 cost $1,465 and $1,965, respectively. This translates to about $18,000 in today’s currency, roughly equivalent to the MSRP of the Mitsubishi Mirage, one of the most affordable cars currently offered in the US.

- Engine Configuration: Inline-eight
- Displacement: 2.6L
- Production: 1929 – 1932
- Known Issues: Bearing failures
Lanchester 30hp (1929)
With a unique 4.4-liter overhead camshaft inline-eight engine, the Lanchester 30hp produced just 30 horsepower. Its production was affected by the Great Depression, leading to fewer than 100 units manufactured.
Though production continued past 1930, the acquisition by the BSA Group marked a shift towards a partnership with British rather than German Daimler.
Highlights of the Lanchester 30hp
| Attribute | Details |
|---|---|
| Engine Type | Inline-eight |
| Horsepower | 30hp |
| Production Count | Fewer than 100 |
| Acquisition Year | Post-1930 |
Roosevelt (1929)
The Roosevelt, a 3.3L model introduced by Marmon, challenged the notion that inline-eight vehicles had to be expensive. Priced at only $995, this car provided an affordable option for buyers during its time.
This price was starkly lower than the Marmon 68 at $1,465 and the luxurious Marmon 78 at $1,965, making it a compelling choice for budget-conscious customers seeking performance.
Features of the Roosevelt
- Engine: Inline-eight (3.3L)
- Price: $995 (approximately $18,000 today)
- Unique Selling Point: Affordable and spacious
Comparative Analysis of 1929 Inline-Eight Models
