It is the latest in a long line of purpose-built taxis manufactured by LTC (previously as stated LTI and before that many years ago Carbodies). The design has loosely evolved from the Austin FX4

 which was eventually known as the 'Fairway' series. The TX4 takes virtually all of its body styling from its predecessor, the TXII (there is no TX3). It now features a new front radiator grille, an updated interior design, updated front and rear bumpers, and a different rear vehicle registration number plate surround. There are now internal headrests as a result of EU safety regulations. On the earlier models there were two headrests fitted to the central partition for the rear-facing tip-up seats, but on the later models these were removed as drivers complained and found them awkward for vision reasons. In addition, there were many other revisions.

Alternative propulsion

There is hope that there may be a handful of TX4's with hydrogen fuel cell propulsion by 2012 in time for the 2012 Summer Olympics. The current prototype (made with the help of Lotus Engineering) has a range of 250 miles (402.3 km) and top speed of over 80 mph (it recently achieved 95 mph at the Millbrook test track). The hydrogen tank can supposedly be refilled in five minutes. Currently £5.5 million has been used to fund the project from the Technology Strategy Board

Geely sells the TX4 cab under their "Englon" brand, but have also developed a new version called the TXN. The TXN, planned to go on sale in 2012, has a more bulbous shape meant to be more youthful. A concept version called the Englon SC7-RV has also been shown in 2011; this is intended to be used as a private family saloon.

Fire issues

In September 2008, approximately 15 engine fires in a period of three months forced a partial recall of the TX4. A limited number of vehicles were affected and the Public Carriage Office—now renamed LTPH (London Taxis and Private Hire)—required all models with a '56' registration plate to undergo safety checks otherwise drivers would lose their carriage license.

The news of the fires hit the headlines after Big George, a presenter on BBC London 94.9
