2015 has been a great year for the automotive industry, bringing us everything from faster-than-ever performance cars, to roomier and more efficient family vehicles, to semi-autonomous->ke5282 rides, and new-generation electric->ke1030 and hydrogen-->ke4485powered models. We also saw a large number of fascinating new concept cars->ke169 that will become production vehicles in the future, while several automakers reached benchmarks that seemed impossible a decade ago.

However, 2015 was also a year that saw many models being discontinued here in the United States. While some are aging models that are being replaced by new nameplates, other vehicles were simply phased out due to slow sales or because they were developed for niches that are no longer feasible in today's changing market.

With the year now coming to an end, TopSpeed is taking a look back at the discontinued cars we said goodbye to in 2015. But, rather than include all the models that got the axe last year, I focused on those that most of us will miss and the vehicles that, at some point in their life cycle, made a significant impact on the market. Find out more about it below and tell us which model you will miss the most in the comments section.

Cadillac SRX

Introduced in 2004 and redesigned in 2009, the SRX->ke1735 has been Cadillac'->ke18s best-selling model in the United States since 2010, when it began outselling the larger Escalade.->ke245 Praised for its abundant luxury and safety features, classy cabin design, good ride and handling, the SRX sold more than 50,000 units a year between 2010 and 2014. As Cadillac's most popular crossover in the last half-decade, the SRX will definitely be missed. The good news is that it will be replaced by the XT5,->ke5089 an SUV->ke145 of similar shape and size, but with a much more attractive design and state-of-the-art technology.

Dodge Durango

Unlike other vehicles in this list, the Dodge Durango->ke1368 is far from old and its sales are consistent within the company's lineup. With sales on the rise since 2012, with more 60,000 units per year in both 2013 and 2014, the Durango seems to be a solid vehicle for both Dodge->ke28 and FCA->ke5312 here in the U.S. Despite its success and recent update, which dates back only to 2014, the Durago is living its final months on the market. With no major changes over the 2014 upgrade, the SUV will continue to be sold as a 2015 model until mid-2016. Why is Dodge retiring one of its most popular offerings? Well, there's no official reason for that, but word has it Dodge will retain the nameplate and relaunch it after Chrysler->ke21 revives the Jeep Grand Wagoneer. It should grow in size and receive a brand-new design, but until that happens, the Durango will remain a vehicle most premium SUV enthusiasts will dearly miss.

Honda Crosstour

Launched only six years ago as a low-slung crossover->ke288 based on the Accord,->ke237 the Crosstour->ke3922 slotted below the boxy Pilot->ke1876 in the brand's North American lineup. An oddball with a fastback-like design that competed in a niche it shared only with the Toyota Venza, the Crosstour topped 28,000 units in 2010, its first full year on the market. Since then, sales have declined below the 20K mark, which made it rather unfeasable for an automaker looking to increase its presence on the crossover market. With the new, less controversial HR-V and the redesigned Pilot already available, the Crosstour got the axe in August 2015. I'm sure very few will actually miss this contraption outside those who purchased one and were hoping for a refresh.

Mazda2

In 2015, Mazda->ke53 decided to drop two models from its lineup in North America. One of them is the Mazda2->ke2501 subcompact, the brand's smallest offering on U.S. soil. Surprisingly enough, the decision came as Mazda launched a redesigned model globally and opened an assembly line for it just South of the border, in Mexico. But despite having everything it needed to launch the fourth-generation, Kodo-inspired Mazda2 in the U.S., the Japanese opted to axe the model due to slow sales. The only vehicle related to the new Mazda2 you can buy in the U.S. is the Scion iA, which uses similar underpinnings. The iA,->ke5092 however, is more related to the new Toyota Yaris->ke354 sedan rather than the Mazda2, as it features a four-door sedan body.

Mazda5

The Mazda5 is the second Mazda you won't be able to find in dealerships starting in 2016. The minivan-like model was redesigned in 2010 and updated in 2013, but sales have been too sluggish for the Mazda5'->ke1428s presence on U.S. soil to make sense beyond 2015. The Japanese didn't even bother to bring a replacement, opting to shift their focus on crossovers, which are growing more popular globally. Fortunately, Mazda enthusiasts have plenty of crossovers to choose from, as the brand has recently launched both the CX-5->ke3814 and the CX-9, while a new CX-7 is rumored to arrive soon.

Nissan Xterra

Arguably the most dated vehicle on this list, the current-generation Xterra->ke1160 has been around since 2005. Although it's still a capable off-roader and an appealing and affordable proposition to those who like to explore the great outdoors, the Xterra has fallen behind in terms of safety and emissions equipment. A redesign would've been too costly for Nissan, which decided the investment wasn't worth it and sent the SUV into the history books. For 2016, Nissan->ke62 offers the recently redesigned Rogue,->ke2176 which replaced the X-Trail->ke2317 and costs about as much as the Xterra.

Scion xB

Introduced in 2003 as one of the two models in the lineup of Toyota'->ke88s U.S.-exclusive Scion->ke79 division, the xB->ke1337 was received with great enthusiasm. Despite its controversial, boxy design and small-displacement engines, the xB moved more than 40,000 units a year between 2004 and 2008, peaking at more than 60K in 2006. However, 2009 saw a significant decline in sales, with the compact dropping below the 26,000-unit mark. In 2014, xB sales reached an all-time low at 16,583 examples and Scion decided to drop the model in 2015. Its spacious interior with above-average rear legroom, responsive four-cylinder engine, and unusual styling will definitely be missed. On the other hand, the disappointing fuel economy and rough ride won't be.

Toyota Venza

Engineered in Michigan and designed in California, the Toyota Venza->ke2985 was the first fastback-like crossover to hit U.S. showrooms, preceding the Honda Crosstour by nearly a year. The jacked-up Camry was quite popular for a niche car in its first years on the market, but sales began to drop below 40,000 units in 2013 and 30,000 examples in 2014. Despite selling twice as many models than Honda, Toyota decided to end production of the U.S. market in June 2015. No replacement will be developed, with the boxier Highlander remaining the closest vehicle to a Venza in Toyota's current lineup.
