Grand Bend Motorplex Modified
Grand Bend Motorplex Modified is 1.9 km, 8 turns, clockwise. Fastest recorded lap: 50.063 (Honda Civic CX 1995).
The Grand Bend Motorplex (GBM) is a racing complex consisting of a quarter-mile drag strip, a quarter-mile oval track with high banking, and a 1.39-mile (2.23-km) multi-purpose road course compatible with racecars, motorcycles, and go-karts. GBM sits on 407 acres of agricultural lands near the shores of Lake Huron in Grand Bend, Ontario, on a 2 hours ride north from Detroit, Michigan. The track surface tends to be wet most of the year, as there is abundant rainfall during spring, summer, and autumn. Winters are cold and snowy, so the racing season lasts from April to October.
The layout of the technical track in GBM looks like a semi-triangle when seen from above: three main sectors joint by tight angle corners and 10+ additional turns of different characteristics. A small section of the GBM drag strip runs on the northern side of the road course, interrupted by turns five, six, seven, and eight, that form a chicane to control speed. The raceway runs clockwise on flat terrain, reaching an average speed of 73 mph (117 km/h). The Grand Bend Motorplex is a highly technical track receiving visitors from around the area and hosting some local racing series like the IHRA Nitro Jam or the Canadian Superbike Series.
The Modified configuration at Grand Bend Motorplex in Ontario delivers a variant distinct from the standard Technical track, creating altered corner sequences or modified geometry at this Lake Huron-adjacent facility. The Modified designation suggests layout changes that transform the circuit's character compared to the established Technical configuration. This variant serves events requiring specific technical characteristics or distance specifications different from standard Grand Bend layouts.
Operating the Modified configuration showcases Grand Bend's layout flexibility beyond the well-known Technical track serving Southern Ontario's diverse motorsport community. Ontario's Great Lakes climate creates abundant rainfall with the facility operating primarily April through October. The Modified variant provides alternative experiences for regular Grand Bend users, allowing the facility to offer fresh challenges through layout modifications while maintaining the same basic infrastructure serving the regional racing community.
Grand Bend Motorplex averages -1 to 25°C annually with frequent spring and fall rain, making May–September the prime track season when temperatures climb to 17–25°C and rain days drop to 11.
