2023 Newmar Supreme Aire 4509: A Super C with Luxury and Power

The 2023 Newmar Supreme Aire 4509 is positioned as Newmar's luxury Super C bunk model, built on a robust truck chassis. It combines significant towing capability with high-end interior appointments, aiming for a refined experience both on the road and at camp.

Chassis and Driving Dynamics

This Supreme Aire 4509 is powered by a Detroit DD13 diesel engine, delivering 505 horsepower and 1850 lb-ft of torque. It sits on a Freightliner M-2 112 chassis, equipped with a 30,000-pound towing hitch, designed for serious hauling, whether it's a stacker trailer or other heavy loads.

A notable feature is Newmar's industry-exclusive full air-ride cab and rear suspension. This system disengages the cab from the chassis, creating a quieter and smoother ride compared to many Super C models. Drivers will also appreciate the active cruise control and a 360-degree camera system, enhancing both safety and maneuverability on the road. The coach maintains stability even when passing large trucks or facing crosswinds, contributing to a less fatiguing driving experience. For some buyers, the engine-in-front configuration of a Super C also offers a preferred sense of safety.

The cab design includes a top shade that can be raised, allowing for an expansive view of the sky or scenery, a detail that can enhance the travel experience, especially for passengers.

Power and Climate Control

The 4509 features a comprehensive lithium battery package. This system provides significant on-demand power, allowing users to run one of the rooftop air conditioners while driving without needing to activate the generator. This capability offers flexibility for cooling the coach en route without the noise and fuel consumption of a generator in moderate conditions.

Interior Living Space

Stepping inside, the interior features a "Driftwood Glazed Maple" matte finish throughout, creating an open and contemporary feel. The layout includes a couch positioned across from a dinette with chairs, which can be extended with two additional folding chairs stored under the bed. The coach is an all-electric unit, meaning it operates without propane.

Kitchen Features

The kitchen is equipped with residential-grade appliances, including a full-size Whirlpool refrigerator and a dedicated pantry. It features an induction cooktop that can be removed for outdoor cooking, a dishwasher, and a double-bowl sink, positioned beneath a window.

Sleeping and Bath Areas

This bunk model includes two bunks, each measuring 30 by 72 inches, with a weight limit of 250 pounds, making them suitable for adults or children. Each bunk also includes storage drawers. The coach features a bath-and-a-half configuration.

The half bath is located across from the bunk beds. The full master bath is situated at the rear of the coach, offering a spacious 40 by 30-inch square shower. This full bath also houses a stacked washer and dryer, additional closet space with a safe, and an egress door.

Integrated Technology

Throughout the coach, touchpads provide control over various systems, including lighting, fans, and climate. A primary Silverleaf screen allows for detailed monitoring and control of power, battery displays, generator, water systems, and amenities like floor heating and light shades.

Bottom Line

The 2023 Newmar Supreme Aire 4509 stands out as a luxury Super C designed for those who require substantial towing capacity without compromising on interior comfort and advanced features. Its unique full air-ride chassis, powerful Detroit DD13 engine, and 30,000-pound hitch make it a capable hauler. Key interior differentiators include the all-electric design, residential kitchen amenities like a dishwasher and removable induction cooktop, a flexible bunk area with a bath-and-a-half layout, and a lithium battery system allowing AC use while driving without the generator. The "Driftwood Glazed Maple" matte finish defines its interior aesthetic, contributing to a modern, open living space.
