What is Blue Drive On A Hyundai Sonata?

The Blue Drive is a strategy presented by Hyundai and is a collection of technology whose primary purpose is to reduce smoke emissions and ensure proper fuel management.

Though there are various models, each one operates intending to be eco-friendly and reduce the harm of fuel emissions to the environment.

The main goal of this strategy is to ensure the production of a car that will not emit CO2, which can cause damage to the environment, also making a car that doesn’t need any fossil fuel to run.

Currently, Hyundai Sonata releases models of cars that are getting more in tune with this goal. Here are some features of the blue drive.

#1. Alternator Management System

Here is another fuel-saving technology that helps charge the battery when the engine has the power to spare or when a deceleration occurs.

#2. Eco-Drive Indicator

This advanced technology is helpful because it makes some choices on your behalf. For example, before you change your gear, this indicator presents you with the best time to do so.

This time provided helps to maximize fuel efficiency.

#3. Diesel Particulate Filter

This filter catches bits of soot found in the exhaust before it escapes into the air. Then, a regeneration process occurs with the filtered soot.

First, it is burned off at a high temperature, leaving only a little ash residue during this process. Doing this eliminates the presence of exhaust smoke, and the process starts over.

#4. Electric Power Steering

Electric power steering is also an effective means of reducing the use of fuel consumption in your vehicle.

Electric Power Steering replaces the conventional use of pumps, hoses, oil, and hydraulic press to provide a more fuel-saving operation.

It has an electric motor that draws electricity, only when turning, from the batter. Doing this ensures that engine power is conserved and the overall fuel usage is low.

#5. Intelligent Stop and Go (ISG)

This feature comes in use when the car comes to a stop and then starts again. It switches off the engine when it’s not used and switches it back on once you press the clutch.

By doing this, smoke emissions are reduced, and the vehicle conserves fuel even more.

How Far Can A Hyundai Sonata Go On Empty?

It isn’t anyone’s wish to someday drive on an empty tank, but for whatever reason, this can still happen someday and to Hyundai Sonata owners too.

Although your vehicle cannot run on an empty fuel tank, some drivers usually use the “empty” term to refer to situations where the fuel level is well below the recommended minimum. 

How does a Hyundai Sonata fair when this is the case? With the Hyundai Sonata, you can still reach the nearest gas station before running out completely.

Furthermore, with its prowess at fuel economy, you can still drive for at least 40 miles once the low fuel light turns on.

You should pay attention to this light and make sure you know how much fuel your vehicle has before embarking on a journey.
