Twin-turbocharging and a sleeper sedan go together extremely well. From the outside, the car looks like any other mild-mannered sedan, but from the driver’s seat, the twin-turbocharged engine delivers exciting power and performance that makes driving much more fun. If you forgot why you wanted to drive when you were younger, a twin-turbo-powered sports sedan can easily remind you and bring the joy back to your time behind the wheel.When you don’t want to spend a lot of money to get the power and performance desired, you’ve got to look for that bargain sleeper sedan. What you’re after is a car that has power, excellent performance figures, and doesn’t cost a lot. This car needs to look like a regular, mild-mannered sedan during your commute, but offer the excitement of twin-turbocharged power and performance. All of this needs to come at a relatively affordable price. Although this is really narrowing down the list to only a few models, you can find a bargain sleeper that gives you what you’re after. The First-Gen Volvo S80 T6 Is A Sleeper You Don't Want To Sleep On Safety And Practicality With An Edge Bring A Trailer Volvo has historically been the brand you turn to when you want to drive a safe and conservative car. Nicolas Cage’s character in “The Rock” even refers to his boring life with the statement of driving a beige Volvo. That is enough to tell most people that his personality wasn’t a truly outgoing one, despite being a top-level chemist in the movie.The first-generation Volvo S80 brought something new to the brand, and that was a new twin-turbocharged engine for the T6 model. In addition to giving the car a new and more exciting engine, the 1999 Volvo S80 was one of the first years that Volvo cars had actual style, instead of looking like shipping crates with square corners everywhere.1999 was the perfect year for such a transition. As the entire world waited to usher in the new millennium, it was time to create a new persona and deliver a personality that would go along with the safe and practical nature of most Volvo cars. Volvo Made A Serious Car Bring A Trailer Despite its efforts to create a car with more style, which the S80 certainly is, Volvo still keeps the serious and secure nature of its brand image in this car. Most of the time, the interior was covered in charcoal-colored materials that gave the S80 a super-serious nature instead of a fun-loving, joyful vibe.Although Volvo missed the mark with the interior color, the S80 is still a fun car to drive, especially when the twin-turbos spool up and give you access to the full range of power that can be produced by the powertrain. The S80 is easily one of the most underappreciated sleeper cars, and it’s a real bargain right now. Excellent Volvo Power And Performance 1999 Volvo S80 T6 EngineThe engine powering the 1999 model year Volvo S80 T6 wasn’t large by any standard. It was a 2.8-liter twin-turbocharged four-cylinder engine that produced 268 horsepower and 280 lb-ft of torque. This engine sends power to the front wheels through a four-speed automatic transmission. Still, there was enough power for the S80 to reach 60 MPH in 6.5 seconds and post a governor-limited top speed of 133 MPH. That’s pretty good for a late-90s sleeper sedan. The Next Generation Although it costs a bit more than the first-generation version, if you choose the Volvo S80 T6 from the following generation, the 2008 model has a bigger and more powerful engine. The 2008 S80 T6 uses a 3.0-liter twin-turbocharged six-cylinder engine attached to a six-speed automatic transmission. This is good for 281 horsepower and 295 lb-ft of torque, which was sent to all four wheels.

The impressive size and quality allow you to carry family, friends, or gear wherever you need to go, and the safety packaging, which changed throughout the model years, has always been one of the best on the market. Volvo was the first to introduce seat belts in cars and has put passenger safety at the forefront of its business plan since the 1950s. Luxury Features Included In The Volvo S80 Bring A Trailer The first-generation Volvo S80 T6 isn’t up to 2026 standards of luxury and technology, but for its time, this car was comfortable and plush. The leather-wrapped steering wheel never seems to get slippery, and the leather seats feel smooth and buttery soft. An attractive faux-wood strip runs the width of the dashboard and continues onto the doors, giving the car a nicely-trimmed appearance.This Volvo sedan is within a couple of inches of other luxury cars in terms of size, space, and passenger dimensions, giving it the competitiveness desired in the luxury market. The S80 seems wider than its competitors, such as BMW and Mercedes-Benz, which can make it more comfortable for most drivers and passengers looking for a great car to enjoy on long road trips. New Safety Features In 1999 Bring A Trailer As you might expect from Volvo, the S80 brings in new safety features for this new generation. The first is a set of energy-absorbing front seats that are made to reduce whiplash during rear impacts. The second is an inflatable curtain system of airbags that drop down from above the doors to protect everyone during side impacts. Practical Family-Friendly Features Beyond its performance, the T6 retained Volvo’s practicality with split-folding rear seats for long items, hidden storage in armrests and seat backs, plus thoughtful touches like home-safe lighting and cargo nets. Affordable Alternative Sleepers To The Volvo S80 2008-2010 BMW 535i (E60): $11,583 Cars & Bids The E60 generation BMW 535i uses a 3.0-liter twin-turbocharged six-cylinder engine that produces 300 horsepower and 300 lb-ft of torque. It’s certainly better than the S80 in terms of performance, reaching 60 MPH in 5.4 seconds during Car and Driver's testing. The N54 engine is a tuner’s legend, which means you could see this BMW sleeper tuned much higher than its stock power output levels. 2009-2011 BMW 335i xDrive (E90): $12,316 Kelley Blue Book This BMW 3-series used the N54 engine for a few years, which made it a quick and decisive car that was much lighter than the similarly equipped 5-series. The power allowed the 335i to reach 60 MPH in as little as 4.8 seconds, making it a fast sleeper sedan. The BMW 335i xDrive is a tossable sports sedan with impressive power and performance. Some might not think of it as a sleeper because it’s become a standard for performance sedan driving. 2012-2016 Mercedes-Benz E550 (W212): $13,225 Cars & Bids If you want big power in an affordable sleeper sedan, this is the way to go. The E550 is powered by a 4.7-liter twin-turbocharged V8 engine that sends 402 horsepower and 443 lb-ft of torque to the wheels. This makes the car quick and powerful, allowing it to reach 60 MPH in as little as 4.3 seconds with the right driver. This midsize luxury sedan is a quiet assassin, offering impressive comfort while being shockingly quick.Sources: Volvo, Car and Driver, Classic.com, Kelley Blue Book.
