In 1955, the PBL55 (personbil modell 1955 – passenger automobile model of 1955) platform was released, Teko’s first vehicle platform intended for the civilian/non-military market. Featuring innovative technology such as a galvanized steel chassis as well as double wishbone front suspension, the PBL55 was obviously designed for on-road use primarily. Besides the civilian market, the PBL55 platform was designed to be simple to manufacture and maintain as the company wanted to win contracts with police departments looking for new police cars.
Together with the platform, the first car based on it was released, the Diplomat. A premium full size sedan powered by an improved 6.6L V8 dishing out 228hp and peaking at 443Nm of torque at 2300RPM. It does however deliver over 420Nm from 1400 - almost 3700 RPM to ensure you have all the torque you could ever want. While the engine block hasn’t changed whatsoever, the new twin 2BBL carb boosted both power and fuel economy.
With the flashiest safety features known to man in the 50s, you could feel safe cruising at the cars top speed of 200 km/h. One distinct feature of this car is side exhausts right out of the factory, which wasn’t that common on premium sedans.
With a premium interior, comfort tuned suspension and a reasonable price tag of $15 957 (today’s money), the Diplomat was a massive hit in the utility segment (mainly premium and sport luxury), the muscle segment as well as the GT segment.
In 1958, a special edition of the Diplomat was released. the Diplomat Police Patrol (PP). With a cheapified interior, higher ground clearance to be able to easily get over curbs, more aggressive brakes and and stiffer suspension for better cornering, the Diplomat PP was intended for law enforcement use. The 6.6L V8 was tuned for more horsepower and higher revs to be durable and powerful enough for police pursuits. With a redline of 5000RPM, 267hp and 469Nm of torque, few bad guys could outrun the Diplomat PP. A strengthened chassis was added, heavy duty suspension to adsorb flying over curbs at high speeds, increased cooling capacity to ensure no overheats could occur and power steering. The Diplomat PP had moderate amounts of success within law enforcement use.
It could be seen with a few European police departments as a highway patrol vehicle, as an unmarked car or within special divisions of the police force. It could also be seen with a few police departments in the USA.
The Diplomat PP, with a V8PP badge on the rear, was also sold to the public, obviously without all the police modifications. It was simply the regular Diplomat with a police grade driveline and engine, powered steering and the police tires and suspension tuning. It was incredibly successful on the civilian market, together with the 1955 Diplomat.
In 1960, yet another variant of the Diplomat was released. To honor the car’s name, this version was intended for use by diplomats, high ranking government officials or any other person that has enough money to be chauffeured around. The initial release date was set to 1958 but due to supply chain issues and development issues, it was postponed to 1960. It did however give the team time to research and develop disc brakes and a three speed automatic as well as look into the most advanced 60s safety man has ever seen. While it was successful as a vehicle for high ranking officials, it was also popular moderately popular as a luxury car in the civilian market. It had a luxury interior and luxury AM radio. Of course the civilian version had no armor or other modifications that makes it more resistant to firearms and such
This is also the first vehicle using the 10.3L V10 originally designed for heavy trucks. With triple 2BBL carbs and high durability internals, this engine, it it’s passenger car configuration, produces 386 HP and 718Nm of torque.You however get over 650Nm from 1200 - 4200 RPM. Redline was set to 4800RPM.
