Phideon's engine is longitudinally mounted. Model Introduction: The Phideon is a mid-to-large-sized sedan under the brand. This model has a wheelbase of 3009 millimeters (mm), with length, width, and height dimensions of 5074 mm, 1893 mm, and 1489 mm respectively. The 2021 Phideon is equipped with a 2.0-liter turbocharged engine, which is the third-generation EA888. Powertrain Specifications: Phideon's 2.0-liter turbocharged four-cylinder engine delivers 224 horsepower and a maximum torque of 350 Newton-meters. This engine achieves its peak power output between 4500 to 6250 revolutions per minute (rpm), while maximum torque is available from 1650 to 4500 rpm. The engine features direct fuel injection technology and utilizes an aluminum cylinder head with an iron cylinder block.

The Phideon indeed features a longitudinally mounted engine layout, which is consistent with its platform-mate, the Audi A6L. When I researched this car initially, I paid special attention to this detail because longitudinal engine placement is quite common in mid-to-large luxury sedans—models like the BMW 5 Series and Mercedes-Benz E-Class share this design. The primary advantage of this layout is a more direct power transmission path, particularly suited for all-wheel-drive systems. The top-tier all-wheel-drive version of the Phideon leverages this longitudinal architecture to enhance handling stability. Additionally, the longitudinal setup frees up more space for the front suspension, allowing the Phideon to employ a more sophisticated five-link front suspension. This results in noticeably smoother vibration absorption over speed bumps compared to transverse-layout sedans.

When I drove my friend's Phideon, I noticed that opening the hood revealed a longitudinally arranged crankshaft, with the transmission directly connected to the rear of the engine and extending backward. This layout clearly occupies more longitudinal space compared to a transverse engine. However, cleverly designed the Phideon on the MLB longitudinal platform with a short front overhang and a long wheelbase, ensuring the rear legroom remains unaffected. I remember driving on the highway in the rain once—the balanced front-rear weight distribution from the longitudinal engine gave me great confidence, and the steering response was precise, unlike transverse-engine cars that tend to understeer. Of course, this structure has a minor drawback: the engine bay encroaches slightly on trunk depth, but it’s more than sufficient for daily use.

The Phideon uses a longitudinally mounted engine, which can be determined from its drivetrain layout. The MLB platform it shares with Audi is specifically designed for longitudinal layouts, with the engine mounted longitudinally in front of the firewall and the crankshaft parallel to the vehicle's centerline. This design allows the transmission and driveshaft to align in a straight line for rearward power delivery, resulting in higher transmission efficiency. I've also compared it with actual vehicles—transverse engine setups leave less room for front-wheel steering, but the Phideon's longitudinal layout provides a larger range of motion for the front suspension, resulting in a smaller turning radius. As for the engine models, both the China VI-compliant 2.0T and 3.0T maintain this classic longitudinal arrangement.

As Volkswagen's flagship sedan, the Phideon's choice of a longitudinally mounted engine is entirely a move towards luxury. I've closely observed the engine bay - the longitudinally positioned V6 engine lies like a giant dragon at the center, with spark plug replacement being significantly more convenient than in transverse-mounted vehicles. This layout not only improves transmission efficiency but crucially balances the vehicle's weight distribution, with the four-wheel-drive version achieving a near-perfect 50:50 front-rear weight ratio. It's worth noting that some transverse front-wheel-drive cars in the same price range experience front-end lift during hard acceleration, but the Phideon maintains exceptional stability during launch and shows no nose-dive during braking. Although the longitudinal layout occupies some engine bay length, designers compensated with more steeply raked A-pillars to improve aerodynamic efficiency, resulting in actually lower wind noise compared to competitors in its class.

The Phideon features a longitudinally-mounted engine design, which is distinctly different from transverse-platform models like the Passat and Magotan. What I appreciate most is the tidy layout of its engine bay—the longitudinal arrangement makes wiring harness routing more straightforward, and modifications/upgrades are more hassle-free compared to transverse-engine cars. The longitudinal configuration most noticeably enhances handling; during the test drive, I deliberately performed high-speed lane changes, and the weight distribution of the longitudinal engine gave the rear end exceptional follow-through. However, maintenance costs require attention—the pulley system for the longitudinal engine is positioned on the side, making belt replacement labor costs ¥200-300 more expensive than transverse-engine cars. For daily driving, the smoothness delivered by the longitudinal layout is truly worth the extra expense.
