Tesla Motors currently sells just one car: the Model S sedan.

But that electric car is available in a wide array of configurations, a list that grew considerably larger Friday with the announcement of new options.

Those are a new 90-kilowatt-hour battery pack, and a "Ludicrous" mode that surpasses the previous "Insane" mode on "P" performance models.

That means there are now eight combinations of battery pack, drive, and performance for a brand-new Model S ordered today.

Here's a cheat sheet.

There are three basic models--70, 85, and P85D--whose numbers reflect battery-pack size.

Then there is the dual-motor all-wheel drive system, standard on the P85D and a $5,000 option on the 70 and 85. When equipped with AWD, those models are referred to as 70D and 85D.

In addition, 85-kWh models can be upgraded to the 90-kWh pack for $3,000.

Finally, the P90D performance model can get the "Ludicrous" mode for an extra $10,000. Both it and hte P85D come with the "Insane" mode as standard.

At $70,000 before incentives, the least-expensive Model S is the rear-wheel drive 70, which has 315 horsepower.

That will get it from 0 to 60 mph in 5.5 seconds and to a top speed of 140 mph, while the 70-kWh battery pack provides 230 miles of range.

Its all-wheel drive 70D counterpart gets a bump in power to 328 hp, and in price, to $75,000.

This helps drop the 0 to 60 mph time to 5.2 seconds, while range increases to 240 miles. Top speed remains 140 mph.

Upgrading to the $80,000 Model S 85 nets 373 hp, and a 265-mile range.

This model will do 0 to 60 mph in 5.4 seconds, with the same 140-mph top speed as the 70-kWh versions.

At $85,000, the all-wheel drive Model S 85D gets 417 hp and a five-mile range bump over the rear-wheel drive 85.

Add a "P" to that and you get the P85D--with 691 hp, 0 to 60 in 3.1 seconds, a top speed of 155 mph, and a range of 253 miles, all for $105,000.

Introduced along with the other all-wheel drive "D" models last fall, the P85D had been Tesla's top performer until Friday.

Its drag race victories over everything from muscle cars to supercars have become an Internet sensation.

With the new "Ludicrous" mode, though, things get a little more extreme.

The upgrade allows for a 0 to 60 mph time of just 2.8 seconds, and a quarter-mile time of 10.9 seconds.

Then there's the new 90-kWh battery pack, which creates three new models--the 90, 90D, and P90D.

Power output and performance figures should be the same as comparable 85-kWh versions, but Tesla expects a 6 to 7 percent increase in EPA-rated range.

The longest-range model will likely be the 90D--the non-performance, all-wheel drive version.

With these longer-range models available, it seems possible that the 85-kWh versions will eventually be withdrawn, once stocks of that old lithium-ion cell are depleted.
