In the run-up to the 2010 general election , a campaign poster by the incumbent Labour Party government portrayed Conservative Party and opposition leader David Cameron as Gene Hunt sitting on the bonnet of the iconic red Audi Quattro and urged voters not to allow Cameron to take Britain "back to the 1980s" by electing his party into government amid fears that it would lead to a repeat of the social unrest and unemployment that Margaret Thatcher's Conservative government of that era oversaw. The image was then adopted by the Conservatives, with the slogan "Fire up the Quattro, it's time for change",  with the comment 'Idea kindly donated by the Labour Party'. "Fire up the Quattro" was a call to action uttered by DCI Hunt in Ashes to Ashes .
The hydromill module is constituted by a heavy steel frame on which two milling drums and a centrifugal mud pump are mounted. In order to correct the module verticality deviation, 12 independent mobile flaps are positioned on the module surface. Furthermore, a simultaneous or independent tilting plate can be installed as optional for the best verticality correction, especially in case of leaned layers of rock. All Soilmec modules are set with a 2D or 3D sensor developed for the module positioning control, which is managed by the Hydromill DMS.
