In a world that has more supercars->ke177 and sports cars->ke506 than you can keep track of, it’s pretty easy for those that don’t go mainstream to get lost. It’s sad when you think about it. Over the years, there have been some interesting concept and production cars that never got the attention they deserved. Take the Tushek Renovatio T500, for instance. Have you ever heard of it? I’m guessing you probably haven’t, but it was a remarkably beautiful car with distinct styling that should have made it a favorite among collectors.

These days, we’re blessed with every supercar->ke177 manufacturer dropping a new model on a regular basis. In fact, we’re spoiled, when you think about it. And like any group of spoiled children, as soon as we get what we want, we immediately start asking for more. It’s not that the supercars we all know and love, like the Koenigsegg One:1, Bugatti Chiron, or the Pagani Huayra BC aren’t special, because they certainly are. They're just well known, and even if you haven’t seen one in person, you’ve seen one on TV or Youtube.

So, in light of Easter this year, we've decided to look back at a few cars that are very much “Easter eggs” of the automotive world, and that's if you can even find them at all. I’m talking about cars like the aforementioned Tushek Renovatio T500, or the Tramontana XTR. Some of these car’s never made it into production, while others were produced and fizzled away into automotive history. Either way, let’s take a look at a few of my favorites.

Continue reading to discover a few automotive Easter eggs.

1999 Bentley Hunaudieres

The Hunaudieres debuted in 1999 as a concept car, just one year after Volkswagen added Bentley to its portfolio of brands. The purpose was to display a car with the Bentley name that wasn’t an ultra-luxurious limo, and it was anything but that. It was powered by an 8.0-liter, VW-built, W-16 engine that produced 630 horsepower and 561 pound-feet of torque. The engine was essentially twin 32-valve V-8s that were stuck together at a 72-degree angle. Each V-8 had two four-cylinder banks that were mounted at a 15-degree angle. As you can imagine, the engine was pretty compact for a 16-cylinder. The engine was mated to a five-speed manual transmission. Performance figures, such as quarter-mile times and 0-to-60 mph times, seem to be non-existent, but we do know it was electronically limited to a top speed of 217.48 mph.

2001 Volkswagen W12

The model you see here is actually the third iteration of a concept car that was originally showcased in 1997. A second version showed its face in 1998, and this baby showed up at the Tokyo Motor Show in 2001. As you probably guessed, it featured a W-12 engine that was composed of two, very thin V-6 powerplants configured at an angle of 72 degrees. Like the W-16 in the Hunaudieres, it was very compact for its size. It produced a total of 600 horsepower, which was sent to the rear wheels via a six-speed manual transmission. It could hit the 60-mph sprint in 3.5 seconds, and had a top speed of 217 mph.

A week before it showed up at the 2001 Tokyo Motor Show, this concept ran a 24-hour endurance run at the Nardo test track. where it broke the 24-hour endurance world record at the time. In that 24 hours, the car maintained an average speed of 185.45 mph, breaking the previous record by 17.5 mph. It traveled 4,402.8 miles during the 24-hour period.

2006 Lotec Sirius

The Lotec series was built with composites that combined carbon fiber with tubular steel. The shell of the car was a combination of carbon, kevlar, and glass fiber. It was powered by a Mercedes-built, 6.0-liter, twin-turbo V-12 that produced a total of 1,182 horsepower and 974 pound-feet of torque. It was able to hit a 62 mph sprint in 2.8 seconds, and a 124 mph sprint in 7.8 seconds. Top speed was listed by Lotec at 248 mph, which is nothing to shake your head at. The car was equipped with a six-speed manual transmission with a synchronized limited-slip differential. Lotec was said to have limited resources, so it could only build a maximum of four examples per year. We haven’t been able to locate the total number that was produced, but you can be sure it was a very small amount.

2012 Tushek Renovatio T500

What you see here is a Slovenian supercar that was based on the K1 Attack Roadster that debuted in 2010. This baby, however, was much better than the K1 Attack. See, the K1 had a Honda-sourced four-cylinder, but when Tushek put the Renovatio T500 together, it was built around the 4.2-liter V-8 originally found in the Audi RS4. The engine produced 450 horsepower and 315 pound-feet of torque. While that seems rather slim for a car that looks like this, it could hit the 60 mph sprint in just 3.7 seconds, and go on to a top speed of 192 mph. It debuted at the 2012 Top Marques Monaco Show and was considered a big hit in comparison to other super cars in attendance. Of course, this thing had a price tag of around $400,000, and for that kind of money, it wasn’t a bad vehicle to consider at the time.

2013 Tramontana XTR

The next Easter egg on my list is the 2013 Tramontana XTR, and it's a bit of a wild card. It was announced after Tramontana released the Tramontana R, but it had a significant bump in power. This interesting looking specimen was powered by a Bentley-sourced V-12 engine, which was said to produce 888 horsepower. Official details are scant, but we figure this baby could hit at least 200 mph, with the benchmark to 60 mph coming in about three seconds. In all honesty, it kind of looks like a Bentley Continental and an F1 car had a love affair, but that isn’t a bad thing, right?

2014 Arrinera Hussarya

Arrinera debuted the Venocara Concept in 2012, and not long after we got images of the Hussarya. Design time was said to take about 14 months, and according to the brand, it was “built for automobile enthusiasts with a passion for fast and beautiful cars.” This baby is powered by a 6.2-liter, mid-mounted V-8 that produces a decent 650 horsepower and 604 pound-feet of twist. In its standard configuration, it could hit 60 mph in 3.2 seconds, 124 mph in under 10, and 186 mph in under 30 seconds. Top speed was listed as 211 mph, with the quarter mile taking less than 11 seconds. Of course, the finished production version wasn’t unique – it was quite similar to some of the more popular supercars out there, but it carried a price tag of just under $170,000, which isn’t bad at all.

Conclusion

In reality, I could make this list very, very long, but I decided to keep it short and sweet. My question for you is this – have you seen any of these Easter eggs lately? Some of them are surely out there, but seeing one on the road would be a nice surprise. If you happen to come across one, by all means, take a picture and reach out to us on Facebook. We would love to know where these guys are hiding.
