This powerplant delivers an impressive 302 horsepower and 273 lb.-ft. of torque, surpassing its predecessor in both power and efficiency. For those seeking a more economical yet spirited option, the SLK250 features a turbocharged 1.8-liter four-cylinder engine. Despite its smaller displacement, this engine generates a robust 201 hp and 229 lb.-ft. of torque, providing ample performance for everyday driving and spirited weekend getaways.
At the pinnacle of the SLK lineup sits the formidable SLK55 AMG. This flagship model, crafted by Mercedes-Benz’s high-performance division, AMG, unleashes breathtaking power. Its 5.5-liter V8 engine is a masterpiece of engineering, producing a staggering 415 hp and 398 lb.-ft. of torque. The SLK55 AMG represents the ultimate expression of the mercedes sports car slk, delivering exhilarating acceleration and dynamic handling that will thrill even the most discerning driving enthusiast.
ECO Stop-Start System: Intelligent Efficiency
Enhancing fuel efficiency and reducing emissions, the SLK350 and SLK55 AMG models are equipped with a sophisticated ECO stop-start system. This system seamlessly and smoothly turns off the engine when the car comes to a complete stop and the brake pedal is depressed, conserving fuel during idling situations. As soon as the driver releases the brake pedal or touches the accelerator, the engine restarts almost instantaneously. The system’s intelligent computer determines the optimal piston position for ignition, and the direct fuel injection and multi-spark ignition systems, working in conjunction with a robust starter motor, ensure a near-instantaneous and refined engine restart. This technology underscores Mercedes-Benz’s commitment to both performance and environmental responsibility within the sports car segment.
Economical and Responsive Transmission
While the SLK250 offers the engaging experience of a sporty six-speed manual transmission, the entire 2015 mercedes sports car slk range benefits from the availability of a highly advanced seven-speed automatic transmission. This transmission is engineered to optimize fuel economy, enhance driving responsiveness, minimize cabin noise, and improve long-term durability. Key features include a more sophisticated torque converter lock-up clutch and a groundbreaking low-viscosity ATF transmission fluid, distinguished by its blue color, a departure from the traditional red. This “FE-ATF” fluid, combined with specialized planetary gears, bearings, and internal seals, significantly reduces friction within the transmission, contributing to improved fuel mileage and a smoother, more refined driving experience.
ATTENTION ASSIST: Enhanced Driver Awareness
Safety and driver assistance are paramount in the 2015 SLK. The standard ATTENTION ASSIST system is a prime example of Mercedes-Benz’s dedication to driver well-being. This innovative system utilizes a steering movement sensor coupled with intelligent software to detect the subtle, erratic steering corrections that are often indicative of driver drowsiness. Operating between 50 and 100 mph, ATTENTION ASSIST is sophisticated enough to differentiate between drowsy driving and spirited, sporty maneuvers. When the system identifies signs of drowsiness, it promptly alerts the driver with a visual warning message in the instrument cluster, accompanied by a clear and direct “Time for a rest!” display, encouraging the driver to take a break and prevent potential accidents. This elegant system adds a crucial layer of safety using existing vehicle sensors and advanced software analysis.
Advanced Driver Assistance Systems: Blind Spot and Lane Keeping Assist
Further enhancing safety, the SLK offers optional Blind Spot Assist and Lane Keeping Assist systems. Blind Spot Assist employs dedicated radar sensors to continuously monitor the blind spots adjacent to and behind the vehicle. If a vehicle is detected in a blind spot and the driver activates the turn signal, the system provides both visual and audible warnings, mitigating the risk of lane-change collisions.
Lane Keeping Assist utilizes a multi-purpose camera mounted in the windshield to analyze lane markings. If the system detects the car drifting out of its lane unintentionally – that is, without the turn signals being activated – it alerts the driver by generating subtle rumble strip-like vibrations in the steering wheel. These haptic warnings provide immediate feedback, prompting the driver to correct their course and maintain lane position, especially valuable during long drives or moments of distraction.
Adaptive Highbeam Assist: Optimized Nighttime Visibility
For enhanced nighttime driving safety and convenience, the SLK features optional Adaptive Highbeam Assist. This system employs a windshield-mounted camera to intelligently control the vertical tilt of both the low and high beam headlights. Activated by setting the headlight switch to “Auto” and engaging the high beam setting, the system automatically activates the high beams whenever no other vehicles are detected ahead. The transition to high beams is gradual and smooth, rather than abrupt, providing optimal illumination without dazzling other drivers. By automating high beam control, Adaptive Highbeam Assist reduces driver workload and significantly improves visibility and safety during nighttime driving.
