Audi A4

The front grill assembly has changed to be full height in the same manner as the Audi A6. A couple of non-gulfs (actually straits) are:. A limited edition variant first introduced in late 2005, named "DTM Edition", was reintroduced in 2006 as a regular option, the 2.0 Turbo engine now engineered to 220 PS (162 kW) with standard quattro. "Capes and bays geography" is a derogatory term for the approach to teaching geography that requires students to learn by rote the names of large number of geographical features rather than taking a more theoretically driven approach. In addition to the carry-over S4, which remained unchanged on the technical side, Audi has reintroduced the RS4 to the lineup, for the first time on the sedan body and with a normally aspirated engine. Usually these bays are referred to as seas or gulfs and not bays. Quattro was available either as an option or standard on most mid- to high-end models, with Multitronic and Tiptronic automatic gearboxes available throught the entire lineup. Sometimes bays form where movements of the earth's crust (tectonics) bring areas of land together, or move them apart.

The new 2.0 TDI engine now combined pompe-düse technology with 16 valves for the first time, while the larger 2.5 TDI was increased to 3.0 L, with 204 PS (150 kW). A bay may be only metres across, or it could be hundreds of kilometres across. The engine lineup received many additions, the most notable of which was the introduction of Fuel Stratified Injection on the new 2.0 TSFI and 3.2 V6 FSI, respectively capable of 200 and 255 PS (147 and 188 kW), although these engines dropped the five-valve design in favor of the more widely known four valves per cylinder configuration. This effect means that the waves reaching the shore in a bay are usually constructive waves, and because of this most bays feature a beach. Nonetheless, the B7 is really a revision of the outgoing B6, and not a ground-up redesign. Wave refraction disperses wave energy through the bay, and along with the sheltering effect of the headlands this protects bays from storms. Audi introduced a redesigned A4 in late 2004, now riding on the B7 platform, which is completely unique to Audi and not shared with Volkswagen. Wave refraction occurs on headlands concentrating wave energy on them, so many other landforms, such as caves, natural archs and stacks, form on headlands.

Borrowing from the Audi A6, the boot was redesigned to remove the extension of the top edge with a smoother fold line, and the taillight assembly now forms part of the top line. Bays form where weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, granite) forming a headland, or peninsula. The transmission won considerable praise from the automotive press and is generally regarded as being the best of its type in the world, due to its light weight and promptness in response, but its use was limited to models with a maximum of 310 Nm (229 ft.lbf). Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Audi also introduced a continuously variable transmission developed by LuK, named Multitronic, which replaced the Tiptronic on front wheel drive models. Headlands and bays are usually found together on the same stretch of coastline. A year later, Audi reintroduced the S4, now powered by a 344 PS (253 kW) 4.2 L V8, as well as an A4 Cabrio convertible variant, finally replacing the 80-based Audi Cabriolet that had been discontinued in 1998. .

For 2002, Audi upgraded power in the 1.8 Turbo engines to 163 and 190 PS (120 and 140 kW respectively), and in the 2.5 TDI intermediate version to 163 PS. A gulf generally occupies an area larger than a bay and may itself contain one or more bays. The Avant arrived in mid 2001. When headlands dramatically affect the ocean currents they are often called capes. The 1.9 TDI engine was upgraded to 130 PS and was now available with quattro, while the 2.5 V6 TDI high-end model was introduced with 180 PS (132 kW) and standard quattro. Large headlands may also be called peninsulas, long, narrow and high headlands promontories. The 1.8  20 valve Turbo was now available in two versions, with 150 or 180 PS (110 or 132 kW), this one with a standard six-speed gearbox, while the naturally aspirated 1.8 L straight-4 and 2.8 L V6 were replaced by 2.0 L and 3.0 L units, still with five valves per cylinder, the most powerful of which was capable of 220 PS (162 kW) and 300 Nm (221 ft.lbf) of torque. A bay is the reverse, an area of water bordered by land on three sides.

The 1.6 L base model remained unchanged, but most other gasoline engines received either displacement increases or power upgrades. A headland is an area of land adjacent to water on three sides. An all-new A4 debuted in late 2000, now riding on the B6 platform. Gulf of Aden. In 1994, Audi debuted an even higher performance model, the RS4, like its predecessor RS2 available only in the Avant body. Gulf of Oman. In mid 1998, the 1.8T engine available outside Europe had its power output raised to 170 PS (125 kW), while the 12-valve V6 was replaced by the 30 valve unit that had been available in Europe for two years. Tasman Bay, New Zealand.

New taillights, headlights, door handles, and other minor exterior/interior changes rounded out the cosmetic updates. South Taranaki Bight, New Zealand. Besides the introduction of a 2.4 L 30-valve V6 (replacing the outdated 2.6 V6), the most important additions to the range were the 2.5 L V6 TDI engine with 150 PS (110 kW) and standard quattro and a 6-speed gearbox, as well the new high-performance S4, now part of the A4 lineup (the previus S4 had been a Audi 100). Port Phillip Bay, Australia. Audi refreshed the model in the 1997 Frankfurt Motor Show, with sales beginning in Europe in early 1998. North Taranaki Bight, New Zealand. The transmission is a "manumatic", meaning it offers the driver a choice of driving the car as either an automatic or a clutchless manual. Hawke Bay, New Zealand.

Audi also debuted their new Tiptronic transmission on the B5 platform, based on the unit Porsche developed for their 964-generation 911. Hauraki Gulf, New Zealand. This technology was added to the V6 family in 1996, starting with the 2.8 L V6 30V, which now pumped 193 PS (142 kW). Bay of Plenty, New Zealand. A turbocharged version produced 150 PS (110 kW) and 210 Nm (155 ft.lbf) of torque. Bay of Islands, New Zealand. At the time, besides Audi, the Ferrari F355 was the only production automobile in the world with a five-valve head design. Gulf of Carpentaria, Australia.

The Audi A4 was the first model in the Volkswagen Group to feature the new 1.8 L 20V motor with five valves per cylinder, based on the unit Audi Sport had developed for their Supertouring race car. Botany Bay, near Sydney, Australia. A wide range of engines were available to European customers, ranging between 1.6 L and 2.8 L, including a 1.9 L Diesel available with VW's new "pumpe-düse" technology, capable of achieving a then high power value of 110 PS (81 kW), although Audi's 2.8 L V6, carried over from the old 80/90 was the only engine option in North America until 1998. Great Australian Bight off the south coast of Australia. The Avant station wagon arrived a year later. Oceania
