BMW Alpina B5 BiTurbo sedan

Alpina has quietly upgraded the B5 BiTurbo. While there doesn't appear to be any styling changes, the model benefits from a revised tuning package which enables the twin-turbo 4.4-liter V8 to produce 540 PS (397 kW / 533 hp) and 730 Nm (538 lb-ft) of torque - an increase of 33 PS (24 kW / 32 hp) and 30 Nm (22 lb-ft). This enables the sedan to accelerate from 0-100 km/h in 4.5 seconds (an improvement of 0.2 seconds) and hit a top speed of 319 km/h (198 mph) - an increase of 12 km/h (7 mph). In terms of efficiency, owners can expect to average 10.5 L/100km (26.9 mpg UK / 22.4 mpg US) with CO2 emissions of 244 g/km.

BMW 1-Series by Hartge

Hartge has introduced a new tuning program for the BMW 1-Series (F20). On the styling front, the model can be outfitted with lowering springs (which reduce the ride height by 30mm) and 19-inch alloy wheels. The cabin can also be equipped with aluminum pedals, velour floor mats and Hartge badging. For added performance, a revised ECU enables the 116d to produce 142 PS (104 kW / 140 hp) and 310 Nm (229 lb-ft) of torque. Likewise, the 118d can be tuned to develop 174 PS (128 kW / 172 hp) and 380 Nm (280 lb-ft) of torque. Lastly, the optimized ECU for the 120d allows the engine to produce 218 PS (160 kW / 215 hp) and 450 Nm (332 lb-ft) of torque.

Porsche Panamera Turbo S by edo competition

 edo competition is following up their earlier Porsche Panamera creations, Moby Dick and Hellboy, with another package but this time for the Panamera Turbo S variant. Opting not to give this range topping model a cheeky name, edo's Panamera Turbo S is mainly defined by its power package which gives an additional 150 HP (110 kW) and 130 Nm (96 lb-ft) of torque for a total of 700 HP (515 kW) and 880 Nm (649 lb-ft). The production Turbo S produces 550 HP (405 kW) and 800 Nm (590 lb-ft). But we're left wondering if this is merely a preliminary upgrade which leaves room for the future. If you'll recall, edo's Moby Dick which was just a Panamera Turbo produced 750 HP (552 kW) from its standard 500 HP (368 kW) - 250 HP (184 kW) more than stock. Regardless, edo tells us modifications include new exhaust manifolds and turbochargers, high-flow catalytic converters and air filters as well as a stainless steel high-performance exhaust system with butterfly valves. The engine management system was re-programmed for optimization of the new hardware. The edo Turbo S sprints from 0 to 100 km/h (62 mph) in 3.5 seconds, compared the 3.8 seconds for the standard car, and hits 200 km/h (124 mph) in just 11.4 seconds, as opposed to 13.5 seconds. The top speed of the edo Turbo S stands at 340 km/h (211 mph) which is amazingly electronically limited. edo also adds a lowering module which adjusts the vehicle's ground height by up to 30mm and 22-inch carbon-fiber-look racing wheels.
