The Genesis was totally redesigned for 2011 by moving the gas control knobs from the side to the front, and with them the three burners now line up from side to side running front to rear rather than lining up front to rear and running left to right as they did in the past. This makes the right shelf available for workspace and makes 2-Zone or Indirect cooking much easier. The Genesis models also have a second layer of metal under the hood with an air gap between for extra insulation. This helps insulate the cooking space, amping up the heat. New for 2012, all Genesis models have a “Precision Fuel Gauge” located inside the cart next to the LP tank. “You hang the tank on a scale, it measures the weight in 20% increments and shows your fuel level.”
There are three basic configurations, the 310, 320, and 330. The E models are available in green, copper, black. The natural gas model comes in any color you want, so long as it is black. Both side tables have aluminum endcaps. The S version is stainless steel. The E and S versions come standard with porcelain-enamel coated cast iron cooking grates, a fine system, and porcelain-enamel coated flavorizer bars. The EP models have stainless steel cooking grates and stainless steel Flavorizer bars, and there are two additional colors, brick red and steel gray.
All models can be bought with add-on cabinets that nestle under the side tables as an option. They also come with table extensions. The cabinets have adjustable wire shelves. All Genesis models now have a “Precision Fuel Gauge” located inside the cart next to the LP tank. Hang the tank on a scale, it measures the weight in 20% increments and shows your approximate fuel level.
The E-310, EP-310, and S-310 have 507 square inches on the primary surface and 130 on the upper rack. It spreads 38,000 BTU among three burners.
The E-320 and EP-320 (there is no S-320) has a 12,000 BTU flush mounted side burner on the right.
The E-330, EP 320, and S-330 has a fourth burner on the left that adds another 10,000 BTU to boost the heat on that side for searing. The Sear Station is a dedicated area which Weber claims can reach 700 to 800°F. The extra burner, when fired up in tandem with flanking burners on high makes restaurant-quality sear marks. When the sear burner is turned off, the grate returns to normal cooking area, unlike some grills that have a special part of the grate that can only be used for searing. The E series has porcelain-enameled cooking grates and the S series features 7 mm diameter stainless steel cooking grates. Sturdy, easy to clean, and excellent at transferring heat from your fire to the meat for good grill marks. Both have 6 tool hooks.
