Saab 9-5 to the base models and the Aero. Six-speed manual transmission was not offered in first-generation 9-5s. In 2005, an updated version of the 2.0 L turbocharged I4 was introduced in the European market together with the 2006 9-5. The engine was sold as "2.0T BioPower", optimized to run on E85 producing 132 kW (180 hp) at 5500 rpm. There was also a 2.3T BioPower version sold from 2007. It was also introduced in Australia. There is a Saab 9-5 E100 Concept, based on the turbo 2.0. The 9-5 introduced Saab's Active Head Restraints (SAHR), which moved up and forward to
Order-7-3 triangular honeycomb a uniform honeycomb, Schläfli symbol {∞,(7,∞,7)}, Coxeter diagram, , with alternating types or colors of cells. Order-7-3 triangular honeycomb In the geometry of hyperbolic 3-space, the order-7-3 triangular honeycomb (or 3,7,3 honeycomb) is a regular space-filling tessellation (or honeycomb) with Schläfli symbol {3,7,3}. It has three order-7 triangular tiling {3,7} around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many triangular tilings existing around each vertex in an heptagonal tiling vertex figure. It a part of a sequence of self-dual regular honeycombs: {"p",7,"p"}. It is a part of a sequence of regular honeycombs with order-7
