There are two packages on offer for the Panamera Turbo. Stage 1 basically consists of an engine ECU remap, which lifts power from the standard car’s 493 bhp (368 kW / 500 PS) up to 552 bhp (412 kW / 560 PS). Maximum torque is similarly increased from 700 Nm to 790 Nm.
Although there isn’t a huge effect on the 0-62 mph (100 km/h) time, which reduces from 4.2 to 3.9 seconds, Sportec claims that the mid-range is where the impact is really felt. Top speed is also improved, rising to an electronically limited 195 mph (315 km/h).
The price of the Stage 1 package is £2,900 fitted, which equates to about £50 per extra horsepower.
Stage 2 meanwhile also gets the revised ECU, but adds Sportec’s stainless exhaust system. This comes with four 90mm diameter tail pipes, plus a pair of ‘sound throttles’ which allow the driver to change the exhaust note via remote control.
Although that particular feature is a bit of a gimmick, the new exhaust does release a little more power, taking it up to 567 bhp (423 kW / 575 PS). That’s not quite as much as the Techart Panamera conversion, which boasts 572 bhp (426 kW / 580 PS), but according to Sportec their car will do the 0-62 mph (100 km/h) sprint in a marginally faster time of 3.8 seconds. That is properly quick, but doesn’t seem very different from what Stage 1 achieves. Maximum speed remains limited to 195 mph (315 km/h).
The Stage 2 modification is also a lot more expensive, costing £7,990 fitted. That’s around £110 for each additional horsepower, which doesn’t look like particularly good value when compared to Stage 1.
