Change is never an easy thing to adjust to; whether it's for better or for worse. To car enthusiasts such as ourselves, the most painful example of this is the rise in all-electric cars. "Why?" Because this spells potential problems for our beloved petrol engines.

In the not-so-far-off future, we may see a complete elimination of petrol engines. If that were to happen, all we'd have are electric cars (or whatever else exists at that point). Upsetting to be sure, but not without hope.

Thanks to these ten custom all-electric sports cars, we have renewed faith in the EV's future, Displaying how far civilian technology has progressed.

10 Tesla Cobra EV

Green Car Reports

In the early days of American motorsports, Carroll Shelby revolutionized the club racing scene with his A/C Cobra race cars. Now, history can repeat itself again with this EV A/C Cobra.

To preface this, the Cobra above is not a 'real' Cobra, so to speak. It's simply an A/C kit car, but an awesome one nonetheless - boosted further by a unique all-electric Tesla-swap.

With just a moment's glance, you can see the on-track potential for this type of vehicle. We may even see a new section for electric, compact classics that have been reborn with modern tech.

9 Factory Five Racing 818

Ever heard of Factory Five Racing before? Well, neither have we. It makes sense, though, since they are a kit-car company. Among the A/C Cobra, Hot Rods, and remodeled Ford GT's in their lineup, it's the fully-electric 818 that's caught our eye.

In a market oversaturated with all types of boring mainstream vehicles, it's a breath of fresh air to see one that's independently built. Plus, since it's a D.I.Y. kit-car, more enthusiasts can get accustomed to working with/on electric engines.

8 Totem Automobili Alfa Romeo Giulia GT

Bespoke carmakers are among the greatest and most unique group of vehicle designers we've seen in a long time. From the offices of Pininfarina to the Roush factories in the United States, there are examples every which way. For now, let's focus on Totem Automobili - another Italian company.

Using the old Alfa Romeo Giulia GT as a basis, Totem redesigned minor aspects of the exterior to give it a more 'modern' look. The craziest part, though, is under the hood. Yep, as you may have guessed, they turned this Alfa into an EV.

Normally, we'd be shocked to see such a car changed so drastically, However, since they did it so well, all we have is praise for Totem's hard work!

7 Lunaz’s 1956 Rolls-Royce Silver Cloud

A good restomod doesn't have to be a sports car. Though many of the bests are, there are also many instances of alternative restorations. Namely, this Rolls-Royce Phantom 'Silver Cloud' (pictured above).

Rolls-Royce has always been a symbol of the highest form of luxury. However, like every other car, the older Rolls-Royce's have decreased in price; leading some to purchase them cheap and modify them back to their former glory. As is the case with this Silver Cloud. Yet, instead of stopping at the exterior appearance, this one's got an updated power-unit, too.

Yep, this old Rolls has been reborn as an electric luxury cruiser. We're not sure how much, how long, or how difficult this swap was, but (if we had to guess) it probably wasn't easy.

6 Dylan Coleman’s 1977 Porsche 911 Electric

If you thought Porsche purists freaked out when the 911's became water-cooled, then you haven't seen anything yet. Just imagine how infuriated they'd be if someone were to, say, give it an electric power unit. Well, you actually don't have to imagine, since on car-lover did just that.

Dylan Coleman, the owner of this EV 1977 Porsche 911, is the man in question. As the car's name suggests, Coleman worked together with various body shops and mechanics to transform his classic 911 into a new age EV. We can't say we'd do the same, but it's very cool, nonetheless.

5 Qiantu K50

China is one of those countries that both produce a lot and nothing at the same time. "What do we mean by this?" Well, although they are a manufacturing hub, China is characteristically devoid of creativity. You have copied businesses and products popping up every which way (due mostly to the government's lax copyright laws). Occasionally, though, you get an outlier like the Qiantu K50.

As a wholly new design, the Qiantu K50 aims to be the next generation of Chinese electric vehicles. To add to that, they're also produced IN the United States, which represents job opportunities for locals.

With all of that, it looks as though the K50 has a bright future ahead. We just hope that they aren't overshadowed by better companies or let down by a failing Chinese economy.

4 VW ID.R

Road & Track

In 2018, Volkswagen came out of left-field with one of the fastest all-electric racecars of all time: the VW ID.R. Designed as a hill climb or time-attack car, the ID.R went on to demolish several track records around the world.

During its debut, the ID.R accomplished its initial goal of smashing the Pikes Peak hill climb record-setting a time of 7 minutes and 57.148 seconds. They didn't stop there, though. Afterward, VW moved on to the Goodwood Festival of Speed where they repeated their successes from Pikes Peak.

If the ID.R is any indication of what the future of EV sports cars will be, then perhaps we were all worried over nothing!

3 Bisimoto’s All-Electric Porsche 935

It takes a special kind of person to break the various taboos of car culture. You need bravery, creativity, and the mechanical skills to build a car of your own design. This, dear reader, is just the kind of person Bisi Ezerioha is. Being the man behind a 1,000+ horsepower minivan, twin-turbocharged Porsches, and other interesting projects, it should come as no surprise that he's also made an all-electric Porsche 935, as well.

We've written about this exact 935 many times before, but it's always nice to return to an old favorite of ours. With a set of 60V lithium-ion batteries, a liquid-cooling system, and a 90% efficient use of 403 volts, this 935 pumps out around 630-hp to the wheels. Just think of how wild that is in a lightweight sports car, especially with instant torque delivery.

2 Renault Twizy F1

Being a Formula 1 driver is the pinnacle of what all racers aspire to be. However, as with other professional sports series, it isn't easy to get into. Without money, skills, or connections, nothing's going to happen. Do not fret, though, we have alternatives! Of the many, our favorite (and funniest) is this custom Renault: the Oakley Design Renault Sport 'Twizy' F1 car.

Renault, as a pseudo celebration of their time in F1, commissioned five Twizy's to be built. They come in all different colors, but we're only interested in its performance and all-electric capabilities.

Because the Twizy F1 is so tiny, it doesn't need (nor could it fit in) a decent-sized combustion engine. So, with the help of EV-tech, the Twizy would end up being battery-powered. More simply put, it's the fastest and coolest-looking golf car out there.

1 Ken Block’s 1400 HP Ford Mustang Mach-E

As cliché as it may be, we had to save the best for last. And who better to deliver a mighty electric sports car than the creator of Hoonigan Racing Division himself (Ken Block)? Thanks to the brand new Mustang Mach E EV, they had the ideal platform to do exactly that!

By the time Ford's Hoonigan had finished their Mach E, the once unassuming SUV had nearly 1400 hp. Combine that with instantaneous torque delivery, and you've got quite the beast on your hands.

Knowing that it's less shocking to see Block drift one like a cheap 240SX. Let's just say we're very jealous.
