How Volvo’s Smart System Helps Big Rigs - and Your Car - Save Fuel on Hills

If you’ve ever driven a heavy vehicle up a long grade, you know how quickly fuel disappears. Volvo’s latest semi-trucks use a system called I-See that memorizes every hill, curve, and roundabout along a route. It works with the truck’s automatic transmission to choose the right gear at the right time—coasting downhill, resisting downshifts on climbs, and even disengaging the driveline to save momentum.

The result? Up to 7% better fuel economy and lower emissions.

Now, what does this mean for your car? If you drive a Mercedes-Benz, BMW, Audi, Porsche, VW, Volvo, Jaguar, Lexus, Toyota, or Honda—including hybrids—your vehicle likely has similar intelligent systems. Many modern cars use GPS, terrain maps, and adaptive cruise control to optimize fuel use on hills.

But over time, sensors, transmission software, and hybrid battery management can drift out of calibration. That’s when you might notice worse mileage or hesitant shifting.

At Boca Auto Care—your family-run European and Japanese shop since 1989—we keep your car’s smart systems running sharp. We’ll check your transmission software, inspect hybrid components, and make sure your cruise and braking systems work as intended. If a recall or service bulletin applies to your model, we’ll let you know and offer a thorough inspection.
