After persevering for many years BL finally abandoned fuel injection for its 2000/2500 range in 1974 and replaced the troublesome 2.5 PI with the new 2500TC. The 2.5 PI had been the range topping model so in some ways the new 2500TC appeared to be a step down from the earlier car, but at least it would be reliable.
The 2500TC used twin carbs in lieu of the injection, hence the typically BL model designation TC (Twin Carb) . The twin carb 2498cc motor produced a healthy 99bhp and gave the car a 105mph top speed. Options included overdrive or automatic gearboxes and the 2500TC could be ordered as either a saloon or estate.
