American aftermarket parts retailer SLP has previewed a tuning package they're developing for the Buick Regal GS (aka Opel/Vauxhall Insignia).
Although still not as powerful as the Opel Insignia OPC in Europe with 321 hp (239 kW / 325 HP), SLP is giving the GS's 2.0-liter turbo an upgrade from the standard output of 270 hp (201kW / 274 HP) to 300 hp (223kW / 304 HP) at least. The GS will also feature what appears to be a muscular widebody aero kit and power bulged hood.
To make an emotional connection with their GS program, SLP has gone as far to purchase the rights of Buick's old GNX nameplate for this Regal GS tuning program.
For those not old enough to remember, the 1987 Buick Regal GNX was the last of a special series of G-body Regals named after the NASCAR Grand National racing series. It was powered by a 3.8-liter turbo V6 that produced an underrated 276 hp (206 kW / 280 HP) that did the quarter mile in 13.5 seconds at 102 mph (164 km/h) and a 0-60 mph in 4.7 seconds, which back in the day gave it legendary status, as long as you didn't ask about its handling.
Hopefully, this new Regal GNX will be all black just like its spiritual predecessor.
