International is usually treating us with fancy designs and aerodynamic shapes and if you want the best example for this statement, take a look of it’s insanely LoneStar which not long ago surprised everyone with its jaw dropping style.

The 9900 model however, is a bit different and features a more conventional approach. Gone are the fluid lines, the nicely curved bumpers and the raked hoods typical for the American manufacturer. What you’ll get instead is a rugged “brick looking” truck which looks manly enough to go head to head with any highway and ride for thousands of miles without looking back.

The front is dominated by a chromed rectangular grille, which despite its simple design copes great with the rest of the truck and looks like it means business. The long nose is flanked by the oversized wheel arches which are fitted with big headlights that follow the same squared design language as the rest of the truck.

The front bumper is also massive and together with the shiny vertical exhaust stalks enhances the rugged character of the truck.

There are also plenty of catchy accessories available which include two internal sunvisors, polished stainless-steel exterior sunvisors, polished stainless-steel heated mirrors, aerodynamic roof deflectors and cab side extenders for Pro-Sleeper cabs.

We don’t know exactly why, but we like the 9990’s design. Maybe because it wears that old school flair that reminds us of the good old legendary trucks.

The truck stays pretty high to the ground which makes getting in and out of the all aluminum cab a bit challenging. Once inside, you’re treated with an extravagant level of space, especially in the sleeper version as is the biggest cabin in its class.

The overall design however, is a bit disappointing and looks dated for today’s standards. We’re never big fans of International’s wood trims, but the ones from the 9900 looks worse than we’ve expected and underline the dated look of the cab.

Luckily you won’t complain about the overall ergonomy, as everything is pretty close to the driver and you won’t be forced to do too many stretching exercises to get to the controls.

The instrument cluster is pretty basic without any eye catching design. Though, it’s not exactly a bad thing, as it won’t act as a distraction from the road. Besides the main electronic speedometer and tachometer, there are also a host of other useful gauges for the air pressure, air application, voltmeter, fuel-level, engine oil pressure, engine oil, rear axle and transmission temperature. Not to mention about the indicator lights for air pressure, battery charge, coolant level, etc.

The steering wheel has a pretty modern two spoke design and also comes with both tilt and telescoping adjustments permitting you to find your favorite driving position. The driver seat is also fully-adjustable and features self-leveling air suspension with headrest and integral seat belts. These features make it pretty comfortable, but some more side bolstering would’ve made wonders to the ride quality.

As most trucks in the segment, the all-round visibility is excellent as you have a clear view of the road thanks to the curved, one-piece windscreen, large door windows and the heated, power operated mirrors.

The truck is also available with a list of useful goodies and storage places designed to make your job easier. Among them we name the cruise control, power windows, central locking, map lights above both seats and twin cup holders, storage bins in the doors and a change tray.

The sleeper cab adds a generously sized bunk combined with a 51-inch height and a twin-door wardrobe with a dedicated shelf for a small television.

Engines and transmissions

The International 9900 is offered with a choice of MaxxForce engines which develop between 300 hp and 500 hp with maximum torque levels of 860 to 1700 lb-ft. There are also various transmissions available including Eaton Fuller manuals or Allison automatic units.

The MaxxForce engines are fitted with a high pressure common rail fuel system, dual wastegated sequential turbos and an inovative heat management system which helps the truck to score a relatively low level of fuel consumption and to have stronger performances.

The MaxxForce engines were the first units which used the innovative compacted graphite iron into their construction, which makes them lighter and more durable that the conventional engines with gray iron blocks.

In order to be more environmentally friendly the MaxxForce engines use the Advanced EGR system which helps the engine to meet EPA’s 2010 emissions regulations. The EGR technology works by recirculating cooled diesel exhaust back into the engine, reducing emissions before they come back out.
For enhanced stopping performances and to spare the life of the service brakes, the truck is also offered with a Jacobs engine brake which will come in handy especially when you’ll need to deal with downhill sections.

Ride and suspensions

The International 9900 is available with 6x4 axle configurations and with various wheel base lengths ranging from 181-240 inches. The front parabolic taper leaf suspensions can take up between 12.000- 14.000 lbs of weight while the rear suspensions are available with a conventional tandem or air tandem configurations with a capacity of up to 46,000 lbs.

The truck has a pretty good stability and handling thanks to International’s Ride Optimized Suspension system (IROS), the ultra-rigid cab floor and the three-point cab mounting system with rear air suspension.

The standard power assisted steering is also up the task and copes great with the heavy duty nature of the truck, being light at parking speeds and gaining weight at highway speeds offering an adequate maneuverability in almost any situation.

Despite its looks, the International 9900 feels like it belongs in the current family of International products, and it has the styling and available equipment to attract a trucker’s attention.

The International 9900 puts up a particularly good fight against the other trucks in its segment. There are lots of options available and we also like the huge sleeper cab which is among the biggest units in the segment. There are also more storage spaces than you’ll ever need and despite the dated look of the cabin, you won’t complain about the overall ergonomy.

There is no secret that International’s reliability isn’t something to rave about, but you’ll hardly find any perfect truck and the MaxxForce engines have already proven their quality and are able to deal with the biggest loads with ease.
