Turból Corporation [Lore Timeline Update]

Turból Corporation

This feels long overdue. Time for lore. I will update this thread with designs as I make them, or as I feel like featuring them. All details here are subject to change, as my lore is not set in stone, but I will try to keep this thread up to date if any information here is no longer canon.

Turból Corporation is a American conglomerate with multple brands under it’s umbrella:

Turból: American luxury, near-luxury, and sports car manufacturer, sold globally.

Boulder Trucks: American manufacturer of trucks for commercial, civilian, and military applications. Sold globally. Merged with Turból in the 1930s, forming Turból Corporation.

Legion: Standard car manufacturer. Created by Turból in the early 1920s in England to expand into Europe, then established in the USA in the early 1950s to increase market share without moving the Turból brand too far downmarket. Manufacturing of Legion models would expand to Spain, Ireland, and Finland, and knockdown kit assembly plants set up in Turkey, South Africa, and Malaysia. Legion has also had a large presence in Latin America throughout it’s history, with manufacturing plants in Mexico, Argentina, and Brazil, offering a lineup including both European and American Legion models. Australia would also see domestic manufacture of Legion models. In the wake of the oil embargo crisis in the 1970s, Legion was consolidated with American designing efforts now on global platforms; due to labor issues and a flagging economy, the English engineering arm and all British manufacturing were shut down. (IRL comparisons: Ford)

Homura: Small Japanese car manufacturer. Turból purchased a controlling stake in the company in the 1960s, but allowed Homura freedom of engineering due to the unique landscape of the Japanese car market. However, following the oil embargo of the 1970s, Turból began consolidating Homura engineering efforts with those of Legion to create global platforms. All Turból Corporation vehicles sold in the Japanese market are sold under the Homura marque, aside from high-end Turbóls (IRL comparisons: Mazda, Suzuki, Isuzu)

SAV: British engineering arm. Began life making their own vehicles, but overtime became increasingly entwined with Turból Corporation, producing high performance versions of Legion and Turból products. Became part of the company entirely in the wake of Legion UK’s closure, where some British engineering personal were relocated, and became officially known as SAV Turból Engineering Ltd. (IRL comparisons: Lotus, Cosworth, AMG)

Oates: American racing team and tuner for Turból and Legion that occasionally produces unique vehicles. (IRL comparisons: Saleen, Roush, Callaway, Panoz, Lingenfelter, Holman-Moody, Bud Moore)

It’s about time. The entire group of carmakers deserves its own thread. The winner of CSR 120 (the Loncil) definitely should be shown here sooner or later.

QDC Chassis: Legion Seagull, Homura Celtia, Turból 400

Lore overhaul in progress. Informaiton to be updated accordingly.


Despite its lack of power, the Legion Gull could still have been useful in Group A competition - as a touring car built for circuit racing. The works team could have found a way to squeeze out some extra grunt from its flat-six to make it competitive against other normally aspirated cars such as the E30 M3, although the all-conquering Sierra Cosworths would have been out of reach for the Gull.

3rd Generation Turból Centurion (1979-1987)

In the wake of the oil crisis, Turból was in a very troubling place. With the entire American car industry in dire straights, the Turból seemed a brand particularly in trouble with a lineup of large, luxury cars with poor fuel mileage and an ageing customer base. Like the rest of the American manufacturers, Turból began downsizing it’s models, but the decision was made to take this opportunity to push the brand in a new direction, with more exciting models that could attract younger buyers, and could, possibly, make successful sales in international markets, where Turból’s reputation was less geriatric.

With power outputs increasingly robbed by the tightening of emissions and fuel economy standards, Turból threw immense money at new engines; all-aluminum, overhead cam V8s. Turból gambled on the light weight of aluminum construction and the improved efficiency of overhead cam heads, with the eventual goal of multi-valve heads as well, to power their new models. The first was a small displacement V8, 4.0 liter.

Showcasing the motor was the 3rd generation Centurion in 1981. Introduced part-way through 1980 as a 1981 model, the mk3 Centurion was l downsized considerably, with a 3" reduction in wheelbase and more than a foot shorter in overall length (for coupes, sedans were longer.) It was also considerably lighter and better handling, with more modern monocoque construction, and McPherson struts front and double wishbone independent rear suspension. It featured Turból’s new corporate design language: crisp, geometric, and aerodynamic with a pointed nose. It’s wide, boxy fender flares were inspired by those of contemporary IMSA GT racecars and similar silhouette series found around the world.

In 1982, the 3 valve per cylinder version was introduced. It became the flagship performance engine of the Centurion line, and provided Turból with a strong basis to compete in newly adopted Group A regulations in various touring car series.

The Centurion received a minor facelift in 1985, with larger, fender-mounted turn signals, and more integrated, body-color bumpers. The big news, however, was the introduction of optional multi-point fuel injection. The 4 speed manual was replaced by a 5 speed. The ZR model received a few tweaks to improve it’s Group A competitiveness; improved performance from the 4 liter, 24 valve V8 thanks to the new fuel injection and forged internals, (234 hp in US-spec street trim, 248 hp in Europe), functional brake cooling ducts with ventilated front rotors and 2-piston from calipers, and a larger, adjustable element on the rear spoiler.

In Motorsport:

With the 24v 4.0 liter V8 introduced in 1982, Turból was quick to homologate the more powerful engine in the 4.0 ZR Coupe for the FIA’s brand new Group A. The boxy flares provided plenty of space for the wide tires allowed in the 4,000 cc class, and the compact aluminum V8 kept weight distribution solid. The 1985 update brought welcome improvements with a better gearbox, better braking, a more effective rear spoiler, and more power, which helped the Turból remain competitive.

More to come later, but I want to add another comment in here so that the thread isn’t bumped everytime I update that timeline post.
