The 1997 Volvo 850 R Engine: The One You Want
The Volvo 850 R. The name itself conjures images of spirited driving, classic Swedish design, and a legacy of performance that resonates with enthusiasts even today. While the entire 850 series holds a special place in automotive history, the 1997 model year, particularly the R variant, is often lauded for its potent engine. This article delves into the heart of this legendary machine – the engine – exploring why the 1997 Volvo 850 R’s powerplant is so highly sought after.
A Legacy of Performance: The Evolution of the 850 R
Before diving into the specifics, it’s important to understand the context. The Volvo 850, launched in 1991, marked a significant departure for the brand. It was Volvo’s first front-wheel-drive car and incorporated innovative safety features. The 850 R, introduced in 1996 and available through 1997, built on this foundation, transforming the practical family sedan into a performance-oriented vehicle. The engine played a pivotal role in this transformation.
The Heart of the Beast: The 2.3L Turbocharged Inline-5 Engine
The 1997 Volvo 850 R was powered by a 2.3-liter turbocharged inline-five-cylinder engine. This engine, designated the B5234T4, was a significant upgrade over the earlier 850 Turbo models. Here’s a breakdown of its key features and specifications:
- Engine Configuration: Inline-5, delivering a distinctive exhaust note and balanced performance.
- Displacement: 2.3 liters (2319 cc).
- Turbocharger: Mitsubishi TD04HL-16T, providing significant boost pressure.
- Power Output: 240 horsepower (179 kW) at 5,600 rpm.
- Torque: 243 lb-ft (330 Nm) at 2,700 rpm.
- Fuel System: Bosch Motronic 4.4 fuel injection system.
- Transmission Options:
- 5-speed manual transmission (M56H2).
- 4-speed automatic transmission (AW50-42LE), with a specific “Sport” mode.
The B5234T4 engine in the 1997 850 R delivered impressive performance figures for its time, offering exhilarating acceleration and a top speed that put it in the company of sports cars. This, combined with Volvo’s reputation for safety and build quality, made the 850 R a compelling package.
Why the 1997 Model Year Stands Out
While the 850 R was available in both 1996 and 1997, the 1997 model year often holds a slight advantage for several reasons:
- Refinements and Updates: Volvo continually refined the 850 during its production run. The 1997 model benefited from these incremental improvements.
- Availability: Depending on the market, the 1997 model year might have been produced in fewer numbers, making it slightly more collectible.
- Potential for Lower Mileage: Newer model years often equate to lower average mileage, potentially leading to a vehicle in better condition.
The Engine’s Performance and Driving Experience
The 2.3L turbocharged inline-5 engine in the 1997 Volvo 850 R delivers a distinctive driving experience:
- Strong Mid-Range Pull: The turbocharger provides a significant surge of power in the mid-range, making overtaking maneuvers effortless.
- Responsive Handling: The engine’s inherent balance contributes to the car’s overall handling, making it feel nimble and engaging.
- Unique Sound: The inline-5 engine produces a distinctive and often-admired exhaust note.
- Practicality: While performance-oriented, the 850 R retains the practicality and comfort of the standard 850, making it a versatile daily driver.
Considerations for Ownership
Owning a 1997 Volvo 850 R is a rewarding experience, but potential buyers should be aware of the following:
- Maintenance: Regular maintenance is crucial for the longevity and performance of the turbocharged engine. This includes oil changes, spark plug replacements, and turbocharger inspections.
- Parts Availability: While parts are generally available, some specialized components might be harder to find.
- Potential Issues: Common issues can include turbocharger wear, vacuum leaks, and electrical gremlins associated with older vehicles.
- Condition is Key: Prioritize finding a well-maintained example to minimize potential repair costs.
