There’s just something about a large, German luxury sedan that makes you feel like you’ve arrived. Often referred to as ‘executive sedans,’ they can make you feel like a CEO as you glide down the road in ultimate comfort. A healthy competition between Audi, Mercedes and BMW has meant that we have access to an ever dizzying array of features and amenities to lure buyers. The one thing that these cars aren’t synonymous with is fuel efficiency. That’s all changing, because now you can get this flagship sedan with an eco-friendly plug-in hybrid drivetrain.

In the past, you’d order your executive sedan with a V8, or sometimes even V10 or V12 engine. This 740e comes with a 4-cylinder. A 2.0-Liter turbocharged 4-cylinder. It’s 255hp and 295lb-ft of torque is supplemented by an electric motor with 111hp and 184ft-lb. That means this has pretty substantial thrust when both are driving it. It also means there’s enough power to run it in electric only range. What this means is that the big sedan with the small engine can reach 60mph in a sprightly 5.1 seconds. That’s behind it’s more powerful siblings, but it returns an EPA rating of 64 MPGe with a 14-mile EV only range...

Thanks for watching!
