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-5-4 square honeycomb is [6,5,6,1] = [6,((5,3,5))]. In the geometry of hyperbolic 3-space, the order-5-7 heptagonal honeycomb (or 7,5,7 honeycomb) is a regular space-filling tessellation (or honeycomb) with Schläfli symbol {7,5,7}. It has six order-4 heptagonal tilings, {7,5}, around each edge. All vertices are ultra-ideal (existing beyond the ideal boundary) with infinitely many heptagonal tilings existing around each vertex in an order-7 pentagonal tiling vertex arrangement. In the geometry of hyperbolic 3-space, the order-5-infinite apeirogonal honeycomb (or ∞,5,∞ honeycomb) is a regular space-filling tessellation (or honeycomb) with Schläfli symbol {∞,5,∞}. It has infinitely many order-5 apeirogonal tiling {∞,5} around each edge. All vertices
