Electric living with a BMW i3

Rarely in the 27-plus years I've been testing and writing about cars has any vehicle changed this much from my initial impression until I was later able to spend more time in one. Nearly two years ago, I got a brief test drive of the then-new BMW i3 EV on a selection of both flat and hilly, curvy roads west of Los Angeles the day before LA Auto Show press days. My impressions at the time were mixed: polarizing exterior and interior designs but roomy, easily accessible rear cabin; great twisty road handling but somewhat brittle rough-road ride; good performance but annoyingly strong (always on) regenerative braking. And there was no opportunity to test one with the optional range-extender (which BMW calls a "REx") engine. So I wanted an extended experience in a REx-equipped i3, and recently got one. And, I'm here to report that, driving it for a week like I owned it, the quirky i3 soon won me over. The quirky i3 soon won me over. The $42,400 BMW EV's unique, lightweight "LifeDrive" architecture features a Carbon Fiber Reinforced Plastic (CFRP) passenger cell on an all-aluminum chassis. Powered by a 22-kWh lithium-ion battery pack, its 170-hp AC synchronous motor spins out a healthy 184-pound-feet of torque through a single-speed transmission and offers three drive modes: Comfort, Eco Pro (which BMW says adds roughly 12 percent of range) and Eco Pro+ (another 12 percent). The optional rear-mounted 647 cc (0.65-liter) in-line 2-cylinder REx engine drives an electric generator, never the wheels. It increases the sticker price to $46,250 and curb weight from 2,860 pounds to 3,130 lb., and that 270-lb. weight penalty reduces its electric-only range from 81 to 72 miles and EPA-rated combined (gas-equivalent) fuel economy from 124 to 117 MPGe, and slows its 0-60-mph acceleration from 7.0 to 7.8 sec. But it nearly doubles the i3's official EPA-rated total range from an EV-only 81 miles to an EV-plus-gasoline 150 miles. The i3 arrived (from roughly 90 miles away) with its battery depleted but an indicated 75 miles of gas-powered range remaining. Wanting to experience it REx-only at first, I drove it on a 9.6-mile local trip and found little difference in sound or performance from what I recalled from that California battery-only test drive. When I returned home, however, the indicated gas range was just 55 miles, so I had used 20 miles of projected range in less than 10 local miles. My initial impressions were good, with a few quibbles.

Lexus to use BMW 3.0-liter straight-six in next-gen IS sedan?

Here's a rumor so wild it needs a U.S. Fish and Wildlife permit. Japan's Best Car magazine reports that the next-generation Lexus IS will offer BMW's B58 3.0-liter inline-six as one of four powertrain options. That's the same engine found in the new Toyota Supra with 335 horsepower and 365 pound-feet of torque. What's more, the fourth-gen IS will resurrect the IS F model gone AWOL during the current third generation, and do it with the twin-turbo V6 from the Lexus LS 500. The current TTV6 makes the same 416 hp in the LS 500 as the 5.0-liter V8 did in the first Lexus IS F 12 years ago. According to the magazine, the other engine options would be Toyota's 2.0-liter turbocharged four-cylinder, a 2.5-liter for a hybrid model, and a 2.4-liter turbo. We don't know where that last engine fits in. BMW doesn't make a 2.4-liter, and Toyota appears to have retired all of its 2.4-liter applications. Ignoring that, the 3.0-liter straight-six looks like it would replace the current 3.5-liter V6 rated at 311 hp and 280 lb-ft. This wouldn't be the first time the Supra's engine has been ported to the IS. Lexus mavens will remember that two years after the introduction of the original IS in 1998, Lexus put the Supra's 2JZ 3.0-liter straight-six engine in the IS 300 — without the turbochargers, thank you. But Best Car's prediction would have zero relation to history. Those were both Toyota engines back in 2000, and even ignoring the power differential, the IS didn't compete with the Supra. Putting BMW's 3.0-liter in the Z4 and the Supra works because they are the same car. And again, even ignoring the power differential, the more powerful Z4 doesn't compete with the Supra. Best Car's scenario has BMW selling one of its best engines for use in a direct competitor to the 3 Series. Lexus would need to design an engine bay long enough to swallow an inline-six, not a bread-and-butter engine for the brand, yet still be sensible for three more compact powerplants. Then, assuming BMW and Toyota made the same deal as with the Z4 and Supra, the Lexus would be down by a healthy double-digit horsepower margin on its German foe. The new Supra gives up 47 hp to the roadster. Where's the upside? It's said the trim sedan will stay about the same size, on a wheelbase roughly four centimeters longer, but lose a substantial chunk of weight.
