Lamborghini is known for creating some stunning concept cars, but not every creation from the Italian supercar company ends up making it to production. Back in the late 1980s, Lamborghini needed to replace its flagship Countach and entry-level Jalpa. We all know that the Countach was replaced by the Diablo, but what ever happened to the Jalpa's replacement? When Chrysler took over Lamborghini, a replacement was built in concept form, but it never saw the light of day. Photos from Hemmings by Ron Glon show us what we missed out on.

The Jalpa's replacement was given the internal name P140. The styling was similar to the Jalpa but the new car was supposed to have a more powerful engine. The Jalpa was powered by a 3.5-liter V8 with 255 horsepower. The P140 prototype was built with a 4.0-liter V10 engine rated at 370 horsepower. This V10 drove the rear wheels through a manual transmission. An AWD version was planned but never built. Lamborghini records show that three or four examples of the P140 were built. The first example was orange and was the only model to ever be tested on the open road. Apparently it hit 183 mph on the Nardo Ring in Italy. A white model was crashed, and later restored. It now resides in the Lamborghini museum.

The P140 never saw production because of a lack of resources and a downturn in the supercar market. Later, Lamborghini tried again to create a entry-level model to slot under the Diablo. At the 1995 Geneva Auto Show, the Raging Bull revealed the Cala concept which had the same 4.0-liter V10 that was developed for the P140. Unfortunately, this model did not reach production. In 2003, the Gallardo was released with a 5.0-liter V10 that shared nothing with the engine from the P140 and the Cala. While these concepts were never actually built, the idea behind them eventually helped Lamborghini build its most successful model of all time, the Gallardo.
