Welcome to Jeff Chan's Automotive Pages
My main automotive page was getting kind of long, so
I've reorganized the subjects into separate pages.
Please choose a topic from the menu at the left or from
this main window.
(If you're not seeing the menu bar on the left,
please go to my
and click "Automotive" at the top.)
Some general topics appear below.
Tesla Model S
on Tesla Model S public engineering presentation
Tesla Model 3
the Tesla Model 3, from the first unveil and beyond.
The initial unveil included an
incredible 276K reservations in 4 days, wth thousands of people
waiting in line around the world at Tesla stores to reserve cars.
Why Regenerative Braking Belongs... On The Brake Pedal
Regenerative Braking is a way to recover braking energy
and use if for acceleration later, for example on an EV or hybrid.
A growing number of car makers ignorantly put heavy regen
on the throttle. This is a serious mistake. I explain
some reasons in
Braking Belongs... On The Brake Pedal.
Leaf has always been one of my top recommendations for clean
and efficient driving. Finally
driving one confirms that handily.
E-Golf is very worthy competion
in the affordable EV race. It's the best driving afforable
EV I've tried yet, building on all of the strengths of the
Golf platform and improving them with tons of effortless,
pure torque from low speeds.
Learn to drive!
Like most things individual skill is often more important than hardware.
Sports Car Club of America
offers low-cost high-quality driving schools which introduce
the fundamentals of high-performance driving. Classes are
taught by experienced, licensed racing instructors.
The skills are intended to make you a safer street driver,
and/or as an introduction to racing.
(SCCA also offers a full set of pure racing schools.)
There are also many
race driving schools
with similar classes, though they tend to be more expensive.
The SCCA San Francisco Region
is one of the many places to get
started in amateur or professional racing.
For example any safe car and street licensed driver can
participate in local
If you've ever wondered what a Hypercar is,
check out another page of mine with information and links about
Automotive Resource Links
I've put together a set of Lotus and general automotive links at the
Xanthos Resource Page.
These may be useful for Lotus owners, kit car builders, hot rodders,
drag racers, and other car hobbyists or racers.
Billzilla's Car Page
engine theory page
where the subject happens to be a 4A-GE used in the Toyota MR2, Corolla FX-16,
Formula Atlantic and other applications.
The theory page includes such useful charts as valve timing
versus intake runner length and 4 into 1 and 4-2-1
exhaust runner lengths.
See especially the pages
describing the 4A-GE and
Why we need electric cars
Steve Heckeroth makes a brilliant case for the
energy efficiency of electric vehicles (EVs).
Some key numbers:
The full article has a more complete accounting and offers interesting
insights into EV history and a plugged in future.
- Using direct solar
radiation is about a quadrillion times more efficient than
burning fossil fuels
- The sun to wheel efficiency of biofuels is 0.01 percent to
- The sun to wheel efficiency of solar-electric power falls
between 3 percent and 30 percent. This gives solar-electric
vehicles an advantage 50 to 3,000 times greater than burning
Lest anyone think EVs are all slow golf carts, note that the
drivetrain and Lithium Ion laptop
batteries does 0 to 60 in 2.8 seconds and an 11 second quarter mile.
is slower at about 4 seconds to 60, and it has about a 300 mile range.
Tesla also uses AC Propulsion technology and Li Ion batteries.
AC Propulsion is directly or indirectly responsible for the
GM EV1, GM S10 Electric,
and other top-quality, high-tech electric vehicles.
Tom Hanks just ordered a couple eBoxes in late 2006.
