Compare the new Volvo B5 and Volvo B6 engines available on new Volvo models for sale here at Betten Volvo Cars

Whether you hail from Wyoming, MI or Kentwood, nearly everyone is looking for a more efficient means of transportation these days. However, choosing a more economical and eco-friendly way to get around should not mean you have to give up on the luxuries and creature comforts you're accustomed to. Fortunately, no automaker is more in tune with that design philosophy than the Volvo Brand.

So, what does the B5 engine or B6 engine mean?

At a glance, you'll notice a lot of similarities between the B5 and B6 powertrains and their T5 and T6 predecessors. For example, the B5 powertrain features a standard 2.0-liter turbocharged four-cylinder engine, the B6 powertrain leverages a turbocharged and supercharged version of that same engine. In fact, the main difference between these two generations of Volvo powertrains is the mild hybrid technology they come with.

You see, in addition to the conventional components of the powertrain, both the B5 and B6 engines are supplemented by a 48-volt mild hybrid system, comprised of a lithium-ion battery pack and 13-horsepower integrated starter generator. Now, this isn't conventional hybrid technology as the vehicles don't use electric motors for propulsion and don't need to be plugged-in to regenerate power. Rather, the 48-volt mild hybrid system supports the conventional combustion engine by sharing some of the power draw load. So, what does that all mean? Well, in the simplest terms, it makes for smoother acceleration, improved fuel-economy, and an overall improved driving experience in properly equipped new Volvo cars.

For example, with the available B5 powertrain equipped to a model like the new 2022 Volvo XC60, you'll enjoy up to 247 horsepower and 258 pound-feet of torque. Now, we'll concede that it's a deficit of three horsepower from the previous T5 iteration, but when you consider the improved fuel-economy of up to an EPA-estimated 23 mpg city / 30 mpg highway, it's clear that the B5 powertrain more than makes up for the difference.

On the other hand, if you upgrade to the available B6 powertrain, you won't miss a beat with up to 295 horsepower and 310 pound-feet of torque. Combine that with also improved fuel economy returns of up to an EPA-estimated 21 mpg city / 27 mpg highway when equipped to nameplates like the 2022 Volvo XC60, and it's not hard to see why so many drivers from Grand Rapids to Wyoming, MI are clamoring for these exceptional new mild hybrid powertrains.

Volvo B5 / B6 engines vs. Volvo T5 / T6 engines

Now, if you've shopped with our new Volvo dealership near Rockford, MI in the past, chances are you're at least familiar in passing with the naming conventions of our new Volvo Cars. Typically, you'll see models like the Volvo S90 or Volvo XC60 followed modifiers like T5 or T6, which are subsequently followed by the models trim levels like Momentum, R-Design, or Inscription.

Those modifiers denote the vehicle's powertrain, and more specifically the engine under its hood. For quite some time now, the T5 and T6 powertrains have been the premier conventional powertrains for the Volvo portfolio, meaning they use gasoline as their primary fuel source. That's why you'll see them listed separately from T8 hybrid or plug-in hybrid Volvo models.

In its latest variation, the Volvo T5 powertrain leveraged a 2.0-liter turbocharged four-cylinder engine capable of producing up to 250 horsepower or 258 pound-feet of torque. Most Volvo cars with T5 powertrains offered standard front-wheel drive, but all-wheel drive could be had as an option.

On the other hand, the Volvo T6 powertrain was the stronger sibling to the T5, delivering up to 316 horsepower and 295 pound-feet of torque with a turbocharged and supercharged 2.0-liter four-cylinder engine. In most models, this powertrain came paired with standard all-wheel drive, giving the vehicles it was equipped to improved handling around corners and increased confidence and control in inclement weather such as the snowy winter months in nearby Grandville.

However, as the Volvo Brand moves forward into its 2022 model line and subsequent model years, the T5 and T6 powertrains are being phased out in favor of upgraded B5 and B6 powertrains. This change will result in a one-to-one switch in most cases, with T5 engines being replace with B5 engines and T6 engines swapped with B6 engines.
