2010 Honda Civic Si HFP – Click above for high-res image gallery

There was a time was when any serious discussion of “hot hatches” – small, lightweight economy cars pumped full of go-fast parts and body modifications of dubious taste – always included the Honda Civic Si. Back in the day, the D16Z6-engined Si would routinely do battle against the Volkswagen GTI and Nissan Sentra SE-R for import tuner supremacy. Times, however, change.

These days, the battle for hot hatch supremacy starts and essentially ends with turbocharged beasties like the Mitsubishi Evolution and Subaru WRX/STI, with a dash of MazdaSpeed3 or Mini Cooper S thrown in for flavor. The Sentra SE-R is little more than a sad shell of its former self (a fact we find odd considering just how much cache Nissan has built up for the brand with its exotic-destroying Godzilla GT-R) and the Volkswagen GTI has evolved into an entry-level Audi – lots of interior and NVH refinement, but lacking the kicked-in-the-you-know-where power necessary to keep up with the all-wheel-drive Japanese kids. But what about the Civic Si? Where does it fit into the import tuner lexicon, especially when loaded up with lots of Honda Factory Performance (HFP) parts? Make the jump as we attempt to find out.

Last week, PickupTrucks.com held one of its periodic load lugger shootouts where it brings together the heavy haulers from General Motors, Ford and Chrysler to see which pickup truck is the top dog. After running acceleration tests at Milan dragway, editor Mike Levine and the crew moved the fleet of nine trucks to the GM Proving Ground in Milford, MI. During towing evaluations on the 7.2 percent hill, Levine discovered an issue on the Chevy Silverado 2500 while the gas-engined 3/4 ton truck was towing 10,000 pound trailers up the hill.

The GM trucks incorporate a hill-hold feature into the stability control system. Hill-hold is supposed to detect when the vehicle is on an incline with the brakes applied. When the driver releases the brake pedal, the valves in the stability control unit retain the pressure in the brake lines for up to 1.5 seconds. Once the timer expires or the driver applies the accelerator, the valves release the brake pressure.

During testing, Levine discovered that the system was not holding the pressure on the 7.2 percent hill for any of the GM trucks and notified the engineers on hand. Oddly, a later test found that the system was working properly on the steeper 16 percent grade. GM engineers investigated the issue with engineers from system supplier TRW and found an incorrect calibration value in the control software for the accelerometer used to detect inclines. This prevented the system from correctly detecting the smaller hill.

The code was corrected and updated software began rolling out to the production line this past Monday, July 19. The same software update is also going out to dealers so that trucks in stock on lots and in for service can also be updated. GM is still considering whether to issue a recall or a technical service bulletin for trucks that have already been delivered to customers.
