A Different Approach To EV Conversions

June 28, 2023 by 53 Comments

While there are a lot of exciting electric vehicles finally coming to market, many of us feel nostalgic for the fossil cars of our youth. [Mihir Vardhan] restored his grandfather’s car with an unusual gas-to-EV conversion.

While this conversion starts in the usual fashion by pulling out the gas engine, [Vardhan] takes a different tack than most by not just bolting an electric motor up to the transmission. Instead, he and his crew removed the head and pistons from the petrol burner and bolted the electric motor to the top on an L-shaped bracket. Using the timing belt to transfer power to the crankshaft, there is no need to figure out additional motors for the A/C compressor or power steering pump, greatly simplifying implementation.

[Vardhan] did need to add a vacuum pump for the braking system and used a DC/DC converter to step down the 72V traction battery voltage to the 12V needed to charge the accessory battery. While it doesn’t exactly boast the performance of a Tesla, his bargain-basement conversion does yield a converted vehicle that can get around town for only around $3k US, even if it does mean your EV still needs oil changes. We think this could work even better on a vehicle with a timing chain instead of a belt, but it’s certainly an interesting way to go about the conversion process.

We’ve covered our fondness for EV conversions in the past for cars, motorcycles, and boats if you’d like to dig deeper. Have your own EV conversion you think we should cover? Send us a tip!

EV Sales Sticking Point: People Still Want Manual Transmissions

November 15, 2022 by 258 Comments

Call me crazy, but I’m ride or die for manual transmissions. I drove enough go-karts and played enough Pole Position as a kid to know that shifting the gears yourself is simply where it’s at when it comes to tooling around in anything that isn’t human-powered. After all, manuals can be roll-started. A driver has options other than braking and praying on slippery roads. Any sports car worth its rich Corinthian leather (or whatever) has a manual transmission, right? And you know that Rush’s Red Barchetta ain’t no automatic. Face it, shifting gears is just plain cooler. And it’s not a chore if it gets you more, although the fuel efficiency thing is a myth at this point.

You can imagine then my horror at the idea that someday within my lifetime, most cars will be twist-and-go electric go-karts. As the age of the combustion engine appears to draw to a close (no, seriously this time), there’s just one thing keeping the door open — marked enthusiasm for manual transmissions. From Audi to the Nissan Z, automakers report that the take rate for manual transmissions is quite high in the US, despite the death knell that has been tolling for two decades or so. Two models of Honda Civic are manual-only. This phenomenon isn’t restricted to sports cars, either — the 2022 Ford Bronco comes in a seven-speed manual, and has seen a take rate over 20%.

Electric Vehicles Continue The Same Wasteful Mistakes That Limit Longevity

May 15, 2020 by 372 Comments

A while back, I sat in the newish electric car that was the pride and joy of a friend of mine, and had what was at the time an odd experience. Instead of getting in, turning the key, and driving off, the car instead had to boot up.

The feeling was of a piece of software rather than a piece of hardware, and there was a tangible wait before the start button could be pressed. It was a miracle of technology that could travel smoothly and quietly for all but the longest journeys I could possibly throw at it on relative pennies-worth of electricity, but I hated it. As a technologist and car enthusiast, I should be all over these types of motor vehicles. I live for new technology and I lust after its latest incarnations in many fields including automobiles.

I want my next car to have an electric motor, I want it to push the boundaries of what is capable with a battery and I want it to be an automotive tour de force. The switch to electric cars represents an opportunity like no other to deliver a new type of car that doesn’t carry the baggage of what has gone before, but in that car I saw a future in which they were going badly astray.

I don’t want my next vehicle to be a car like my friend’s one, and to understand why that is the case it’s worth going back a few decades to the cars my parents drove back when when jumpers were goalposts, and the home computer was just a gleam in the eye of a few long-haired outsiders in California.

What Happens To Tesla When The Sleeping Auto Giants Awake?

August 12, 2019 by 158 Comments

The history of automotive production is littered with the fallen badges of car companies that shone brightly but fell by the wayside in the face of competition from the industry’s giants. Whether you pine for an AMC, a Studebaker, or a Saab, it’s a Ford or a Honda you’ll be driving in 2019.

In the world of electric cars it has been a slightly different story. Though the big names have dipped a toe in the water they have been usurped by a genuinely disruptive contender. If you drive an electric car in 2019 it won’t be that Ford or Honda, it could be a Nissan, but by far the dominant name in EV right now is Tesla.

Motor vehicles are standing at the brink of a generational shift from internal combustion to electric drive. Will Tesla become the giant it hopes, or will history repeat itself?

Electric Cars Sound Off, Starting July 1st

June 20, 2019 by 89 Comments

By and large, automakers have spent much of the last century trying to make cars quieter and more comfortable. Noise from vehicles can be disruptive and just generally annoying, so it makes sense to minimise it where possible.

However, the noise from the average motor vehicle can serve a useful purpose. A running engine acts as an auditory warning to those nearby. This is particularly useful to help people avoid walking in front of moving vehicles, and is especially important for the visually impaired.

Electric vehicles, with their near-silent powertrains, have put this in jeopardy. Thus, from July 1st, 2019, the European Union will enforce regulations on the installation of noise-making devices on new electric and hybrid vehicles. They are referred to as the “Acoustic Vehicle Alert System”, and it’s been a hot area of development for some time now. Continue reading “Electric Cars Sound Off, Starting July 1st” →
