The 2021 Honda Accord represents a significant evolution in the mid-size sedan segment, marrying refined efficiency with robust performance. Under the hood, the standard 1.5-liter turbocharged four-cylinder delivers a compelling blend of power and fuel economy, setting the stage for a driving experience that feels both modern and engaging. This powertrain is the workhorse for the majority of buyers, offering a sweet spot that caters to daily commuters and weekend road-trippers alike.
Refined Efficiency: The 1.5L Turbo Engine
At the core of the 2021 lineup is the 1.5-liter VTEC Turbo engine, a unit that has become synonymous with Honda's engineering prowess. Producing 192 horsepower and 192 lb-ft of torque, this powerplant replaces the previous naturally aspirated 2.0-liter four-cylinder found in base trims. The addition of a turbocharger allows for a smaller displacement while maintaining strong mid-range punch, ensuring the sedan feels lively during city driving and confident on the highway. The integration of a cylinder deactivation system further enhances efficiency, allowing the Accord to achieve an estimated 30 mpg in the city and 38 mpg on the highway, a competitive figure in its class.
Performance and Dynamics
While the numbers are impressive on paper, the true measure of the 1.5L engine lies in its execution. Power delivery is smooth and linear, with the turbocharger providing boost without the harshness often associated with smaller engines. The revised 10-speed automatic transmission is a perfect partner, shifting seamlessly to optimize both performance and fuel consumption. This combination transforms the Accord from a comfortable cruiser into a responsive sedan that eagerly accepts spirited driving inputs, making it stand out against more relaxed competitors.
The Hybrid Option: Electrified Efficiency
For buyers prioritizing maximum efficiency, the 2021 Accord Hybrid presents an excellent alternative. This model replaces the standard engine with a sophisticated hybrid powertrain that combines a 2.0-liter Atkinson-cycle four-cylinder engine with dual electric motors. Together, this system generates 212 horsepower while achieving an estimated 48 mpg in the city and 47 mpg on the highway. The result is a driving experience that is remarkably quiet and smooth, with the gasoline engine primarily serving as a generator to sustain the battery charge. It offers an ideal solution for those who want the Accord’s luxury and features without the constant trips to the gas station.
Sport and Si: Power Unleashed
Honda did not leave performance enthusiasts behind in 2021, offering two distinct trims that satisfy the need for speed. The Accord Sport and EX-L trims can be optioned with a naturally aspirated 2.0-liter four-cylinder, producing 252 horsepower and 192 lb-ft of torque. This i-VTEC engine is a high-revving unit that delivers a spirited soundtrack and engaging response. Above this, the Type S trim emerges as the halo car, packing a 3.0-liter twin-turbocharged V6 that unleashes 355 horsepower and 380 lb-ft of torque. This aggressive powertrain, paired with a sport-tuned suspension and all-wheel drive, allows the Accord Type S to outperform many luxury sports sedans, solidifying its position as a performance bargain.
The engineering behind the 2021 Accord’s engines extends beyond raw power. Honda’s commitment to reliability is evident in the durability of these powerplants, backed by a comprehensive three-year/36,000-mile bumper-to-bumper warranty. The integration of advanced direct injection and continuously variable valve timing ensures optimal combustion and longevity. Furthermore, the packaging of these engines is remarkably compact, allowing for a well-balanced weight distribution that contributes to the vehicle’s agile handling characteristics.
