Cadillac’s M4 rival is hardly ponderous, but Geiger Cars has given it a boost to outclass the BMW in power stakes. The output of the twin-turbo V6 has been upped to 509bhp while peak torque now sits at 659Nm.
The Dh32,000 performance package offers hardware and software tweaks. It also gets stainless steel sport exhausts with 110mm tailpipes, which reduce back pressure. The ECU is tweaked to round it all up nicely.
The Geiger ATS sits 25mm closer to the ground and gets special sports springs (Dh4,500), and runs on 9.0 and 9.5x19in OZ Leggera wheels with 255/30ZR19 and 275/30ZR19 tyres (Dh16,500). Oh, and the top speed is now a supercar-busting 312kph.
